This question is more for the members of the Brotherhood of the Sonosubs.

I just recently have been reading up on all the DIY Sonosubs by "ssabripo" and "steve callas" and "Wild" and many others (forgive me if I did not explicitly mention your username).

In the very near future, I plan on starting my first DIY subwoofer. I unfortunately do not have the option for an IB sub....hence, the next step down would be a Sonosub.

Although I know this will be my first DIY subwoofer, I do not want to start by making one for practice (I do not want to waste my money on something that I don't really plan on using). However, I am hoping the Brotherhood with be able to help me out.

My goal is to have one single amazing Sonosub...for that reason, I am willing to invest in one good driver.

Would you say, that one 18" LMS-5400 is worth is? I only ask because many Sonosub building sporadically have mentioned it but refrain from using it because of its price.

If I see that most will support its purpose, then I plan on ordering one very soon. Please, share your thoughts.

The LMS5400, price aside, is probably one of the best drivers that will be out, bar none! Linear Motor Technology for flat BL vs Displacement characteristics, it has ungodly 40mm Xmax, it can take power out of the wazoo, and it comes in at a tiny 65lbs !!!

However, we've discussed this many times before, that it is not the best driver for an LLT alignment bang for buck, although it will clearly hold its own.

I posted some graphs before, but I can't find them. Willd posted this which is similar:
http://www.avsforum.com/avs-vb/showthread.php?p=9089124&&#post9089124

the LMS5400 will be a very good driver for a sealed or even PR application with tons of power, but as you can see above, it wont be too shabby at all for an LLT design either. As you can see, a 400-500L enclosure, tuned low to 11-13hz, with good power (1500-2500W, as opposed to 700w), and you will have a nice design that will out do the monster ava18 tubes....of course, you will be paying more for driver and amps

hope that helps.

Thanks for getting back and yes that definately helps. Do you have any recommendations as to which single driver would be best suited for LLT sub...once again price aside (well <$1200).

I'm not sure how much under $1,200 it is but the Resonant Engineering XXX 18" may work. http://www.reaudio.com/specs.html#sp_xxx

Also check out the 18" models from Fi Car Audio.

Thanks for getting back and yes that definately helps. Do you have any recommendations as to which single driver would be best suited for LLT sub...once again price aside (well <$1200).
again, you fall into the right category (IMO) for an LMS5400 large EBS alignment (or LLT if you like), since you don't care about price and you want one single sonotube, so I completely understand, and I would whole heartedly suggest the LMS5400 if you can muster it.

if you have capacity for multiple subs, multiple drivers, then obviously that would be a viable option as well, as you could have 2-3 smaller sonosubs with say an RP-L15 or even a tumult 15". If you are not restricted to size, you can also get couple of large sonosubs built on ficaraudio Q18's with modified Q (scott will do that for ya) and that would be fairly close to what the ava18 sonotubes would be.

but again, you are the perfect candidate (as I was, before landing the new ava18 drivers) for an large sonotube with the LMS5400 18" driver. Tune it as shown above to 400-500L, with a tuning of 11-13.5 , and add some nice power, and you will be in so much business it wont be funny.

Ssabripo,

My room is 20' x 30' where the HT is to one side and a bar is on the other side.

Why I would want only one sub:

1) Because its less work, building one as oppose to two

2) For me, for asthetic purposes, I would perfer to have one giant than to have two smaller giants.

If you don't think these are good enough reasons to do only one sub, then I will definately reconsider. Furthermore, my main goal is good distortion free bass. However, if I can get that by building nothing but one main sono, than nothing like it.

And lastly if I am already paying so much for the driver, i do not mind adding a nice amp to make sure it is worked to its potential.

given the above reasons, I would think you will be perfectly fine with a single LMS5400 18" sonosub.

your size room can use a little more if really wanted reference levels down deep, but a single 18" 5400 will have plenty of energy for that room.

I would be looking at amps now....several to choose from, and you want one that has plenty of power. ICE, Crown XTi, and others come to mind....even a bridged EP2500 would do ok.

What would you think about the Crown XTi 2000. I only ask specifically about that model because someone local is selling a brand new one for 500. Do you think it will match well with the 5400?

new ones are $699...so 500 is not too bad, but if you shop around you may find better. Also, you want to look into the 4000 to be honest, as the 500 will struggle to adequately power the 5400.

you want a good 2000W or so to really get things going with the 18" 5400.

:) Okey dokey.

Although I know this will be my first DIY subwoofer, I do not want to start by making one for practice (I do not want to waste my money on something that I don't really plan on using)
I definitely hear you on this one, I approached it the same way.

Would you say, that one 18" LMS-5400 is worth is?
Ehh, depends. What are your other speakers? What levels do you typically listen at? How far will you be sitting from the sub and how large is your room?

Do you have any recommendations as to which single driver would be best suited for LLT sub
You just missed out on a couple Avalanche 18s for sale, but I think there is another guy on this board considering selling his four. The Avalanche and LMS will both stay linear within their respective excursion limits (LMS more so), and the LMS is capable of about 3db more headroom in similarly tuned designs, but when approaching such a design realistically, there are some port issues and you would need to get a pretty beefy amp to make the most of it. An Avalanche LLT truly eliminates any possibility for port issues and reaches simulated reference levels with 600 watts as compared to 1000 with the LMS. You'd want ~2200 watts to get the most out of the LMS. Because of these things, I feel the Avalanche 18 is a little better suited to a LLT design.

Two, three, and four massive LLT sub setups get talked about here, along with dual driver LLTs and 16 driver IBs, but realistically, under even some pretty insane listening levels, one LLT will be more than enough, especially when compared to the speakers typically in a system. For your purposes, a TC 2000 15" svc might be plenty - just expand a little on the rest of your system and what you are after.

Yeah, besides the price, the LMS isn't ideal for a low-tuned sonosub because of the port issues mentioned. How big of an issue these are isn't clear, but the situation still isn't optimal. I don't consider the needing a good amp bit to be an issue, since something like an Ep2500 or even the Xti 2000 you're considering would work.

Like I've said before, I think the 5400 is better suited for a passive radiator sub. If one truly has no other options and can only go with one driver and has the budget for it, the 5400 is pretty much the best 18" driver you can buy.

Thanks for posting steve,

My current system . Ascent Acoustics 340SE mains and center and 170SE rears powered by the Panasonic XR-55 receiver. The subwoofer is VTF3-MKII. Its a nice sub but I am not really feeling it. I love the ascends and though a bit brite I still like my parasonic xr-55. But I feel the bass is missing in the low low end. And I feel it is not as powerful as I wish it would be in the low end. I have changed the receiver once to Parasound seperates but the bass in the low low end just didnt seem right. I liked it for music but not so much for movies.

And so now I am considering building a Sonosub.

Steve, do you not recommend the LMS-5400...even if I suffice it with plenty of power (over 2200 as you suggested)?

Ascends are nice speakers, but even with dedicated amps, they'd probably get harsh before something like a TC 2000 15 svc LLT. Just after Thanksgiving I was at Ryan's (---k---) home and he was playing WOTW at very spirited levels on his system which consists of Ascend 340 SEs across the front, 170s in back, a Pioneer 1015 receiver, and a dual RLp15 LLT. When the going got rough, the Ascends were getting a little harsh while the LLT was chugging along seemingly effortlessly. I'm not crazy, but I think I even saw and heard the LLT kinda laugh at us, as if to ask "is that all?" :o

How far back would you be sitting from the sub? I'd have to think a TC 2000 would easily fit the bill.

If you were set on a LMS 5400, seeing as you wouldn't really be able to call on all that output capability, I'd go for a really low tune. Something like 550 effective liters with a 6" diameter port that is 28" long being fed with 1500 watts. The port velocity is actually better on the whole with this design than a smaller, slightly higher tuned option.

If the "brotherhood" feels that LMS-5400 should be avoided, then, I will gladly consider something else.

My goal is to have one overkilled sonosub (unless for some strange reason I also get addicted and start building multiple sonos - like many others have).

I only considere the LMS-5400 because many have complemented it for having low THD at even high SPLs.

I am open to ideas for a sigle deadly sono sub.

I have no hesitation admitting that the brotherhood knows better than me. But like I said, a overkilled sonosub would be nice - while although I may not be using to full potential presently, it would be nice to know that I have that power should I need it.

Well there is no better option than the lms-5400 for a "single deadly sonosub".

What about the Elemental Designs 19ov.2? It's got close to 2.5 inches of throw and can take a bunch of power. It's pretty efficient too.

Just throwing out another 18" driver. I didn't see it mentioned.

No offense but what the OP wants is on a much higher level than that driver.

The 5400 offers about 3" peak to peak travel, the motor that drives it is ridiculous, and it can really gobble up power. For having a single driver, there's nothing better that I know of regular sub-drivers than the 5400.



Just the thought of them putting that 4" motor on a 12" driver also is scary...

3" of completely linear peak to peak travel, but a mechanical excursion capability of about 4".

Just to make sure we're clear. ;)

First and foremost, thank you all for your advice.

Next....I tried calling Tcsounds earlier today but had no luck getting in touch with anyone there....I was just trying to find out if the LMS were in stock and ready to be shipped. Left a message and so hopefully they will get back to me by tomorrow.

What would you guys suggest would be a good matching amp for the 5400 (if you can, please suggest one that is good for the money i.e. ep2500 or one without considering price..i.e.one of the crown xti 4000).

Thanks once again.

Crown K2 is one of the best subwoofer amplifiers that I know of. Pair that with a good DEQ and you are set.

Yeah, the Crown K2 would definitely be a good choice. Bit pricey though, but so is the driver.

Basically, you want an amp that is capable of over 2000W RMS at 4ohms. EP2500, Crown XTi 2000 or 4000, Carvin DCM2500....

If was going to use an LMS-5400, I would be tempted to over-engineer my
amplifier needs to ensure the amp remains neutral and offers amazing power
and headroom. Problems is, it's not cheap when you want to consider the higher
end pro amps.

I have the binks pro amp test result and here are some numbers from the test.
The test indicates two channels driven at 4 ohms per channel, 1% THD+N,
two tests, one with 117VAC input and the other with 96VAC 'sagging' inputs.


Crown K2
The amp is rated for 800w @ 4 ohms and it scores big on the higher frequency
test.

117 VAC supply voltage, the power test results;

20hz - 724w per channel, 4 ohms.
1khz - 848w per channel, 4 ohms.
20khz - 1490w per channel, 4 ohms.

96VAC sagging supply voltage, the power test results;
20hz - 446w per channel, 4 ohms.
1khz - 562w per channel, 4 ohms.
20khz - 1285 per channel, 4 ohms.

QSC PL6.0 PFC. [discountined, seek them on the used market]

117 VAC supply voltage, the power tests is.
20hz - 2289w per channel, 4 ohms.
1khz - 2459w per channel, 4 ohms.
20khz - 2890w per channel, 4 ohms.


QSC PL9.0 PFC. [discountined, seek them on the used market]

20hz - 3152w per channel, 4 ohms.
1khz - 3293w per channel, 4 ohms.
20khz - 4801w per channel, 4 ohms.

Power is essentially the same at 96VAC due to the 'PFC design'.

QSC PL6 II {not PFC}
117 VAC supply voltage, the power tests is;
20hz - 1719w per channel, 4 ohms.
1khz - 1893w per channel, 4 ohms.
20khz - 3241w per channel, 4 ohms.

96VAC sagging supply voltage, the power test results;
20hz - 1289w per channel, 4 ohms.
1khz - 1723w per channel, 4 ohms.
20khz - 2853w per channel, 4 ohms.

Comments: Since PFC's can be had only on the used market
and considering the PL6.0 II scores big numbers, in bridged mode
at 4 ohms, this would be a sweet choice.

I don't have the bink test results for other amps of interest so it's
hard to compare these; PLX series, RMX4050, RMX5050, Crown XTI is new,
Lab Gruppen is way too expensive and so is Crown I-tech. Crest 10001,
Crown Macrotech, is also monsters to consider, discountined, seek on the used
market.

Considering that I own a bunch of PLX and a couple of Crest10001's,
factoring in many variables, if you needed only one amp to do the job
of 'monster' at 4 ohms in bridged mode, I'd take two paths;

1. Gamble with used PFC's or discontinued amps as they are monsters, perferring
the PFC's as they don't mind VAC input sag; an issue very important that never
gets addressed in home audio.

2. Play conservative and don't buy discontinued amps, so the PL6.0II would
be on my list, but I'd still seek one on the used market.

Determine your amp budget first then you can figure it out.

If was going to use an LMS-5400, I would be tempted to over-engineer my
amplifier needs to ensure the amp remains neutral and offers amazing power
and headroom. Problems is, it's not cheap when you want to consider the higher
end pro amps.

Nice info thylantyr, and you're correct

I tried to look into used QSC PL....I'd say they are still quite expensive. I am trying to get my hands on a used K2 as well.

As I had mentioned earlier, I found a local seller of the Crown XTi 2000 for $500.

Preferably I would like to cap my budger for the amp at $800 (new or used doesn't matter).

Although I think we might have reached consensus of LMS5400 as a good driver for a single sonosub, the suggestions for the amp seem to vary significantly.

I don't want to go "cheap" on the amp (otherwise whats the point of going all out on the driver), but at the same time I don't want to spend like 2k for the amp.

Some posts earlier suggested the ep2500 which could easily by found for 3 to 4 hundred. I trying to get in touch with someone who was selling the Crown K2 for 700 used - which appears to have been sold since e-mails go unanswered.

But, lets just say for the time being I set my budget at $800 (new or used), any good suggestions then?

Wouldn't two EP2500's, one for each VC, work?

by the time you finish building this thing, several weeks will have passed by....in that timespan, you surely will run into a nice K2 or XTi4000 on sale. At worst, then you can always order either the XTi2000 from your contact for $500, or just get a brand spanking new EP2500 and do the fan mod, run it in bridged mode, and you are set.

at this point, you are splitting some hairs about the amp.....the main thing for you now is to get the drivers, which I believe is still not being shipped.

Amp will definately be the last part of the project. I am still have had no luck getting intouch with someone at Tcsounds for the LMS5400. I am trying to order parts now so I can start work by late Jan early Feb.

I plan on giving them a call again today. If I hear from them, I will definately let you guys know when they will be shipping.

Yeah, the amp thing isn't as easy as it may seem for a driver like this. If you are going to pay the hefty premium for this driver, like thylantyr said, you'll want an amp that can extract all of the performance out of it.....otherwise why get this driver? But in doing so, the amp used would have to be a real monster itself - being able to throw around a good clean 2200 watts from a single amp gets pretty pricey. I'm not trying to be disparaging, really I'm not, but again considering that you're using 340s with a xr-55, I'd echo your thread title "Is it worth it?" Maybe I'm just a cheapskate :D , but what I'd imagine the demands in such a system to be could be handled for much less cost.

Although I rarely agree with ol' Steve ( :p ), he has a very good point. What is the use of getting a monster sonosub with one of the best drivers out there, and some hefty amp, when the rest of your system consists of ascends and a xr-55........unless you plan on upgrading those as well in the very near future ;)

for a system above, a TC2000, RP-L15 sonosub will be more than sufficient....if you want bragging rights for a single sonosub, or just are a plain bassaholic and want to overpower the rest of your system, then sure.....

I;ve given you enough info here to help you out, so I'm not trying to damper the spirits here, but you will be paying mucho dinero for the driver, and mucho dinero for the amp, just to complement some middle of the road gear/speakers.

If I were you, and ONLY if I were you, I would probably do TC2000 sub, with a modded EP series amp, and use the remaining $1-1.5K I would save into upgrading speakers or building my own.... with the money from selling your ascends, plus the potential $1.5K savings, you would have at least $2k to either buy some better speakers or better yet, build my own!!

but hey, I would love to see the first 5400 18" sonosub done, so what the heck.....go for it! :D

Steve,
I definitely agree with you...but if there is one thing that I hate more than anything else is the "what if" factor....its just that it irritates me and though I may be wholeheartedly please with the TC-2000....i have a feeling that the curiosity of the LMS5400 would kill me --> However, I do ultimately realize that this is not a good excuse to "waste" money for unused potential. But, when it comes to me, whenever I am feeling "what iffy"...I usually end up spending more money.

Furthermore, if I do in fact go cheap on the amp, this would only be a temporarily.

None the less, I would love to hear your suggestion for a matching sub for my Ascends and xr-55 (and oh!, it would be nice it if the sub would embarrass the VTF3-MKII).

Wouldn't two EP2500's, one for each VC, work?

This page indicates 2 ohm dual voice coil.
http://www.tcsounds.com/lms5400.htm

Two bridged amps, one per coil would be sweet but 99.99% of the proamps
on the market aren't rated for 2 ohms bridged. Lets say for kicks, the LMS
was dual 4 ohm coils, then using two of the lower cost pro amps in bridged
mode per coil with matched gains would work well.

None the less, I would love to hear your suggestion for a matching sub for my Ascends and xr-55 (and oh!, it would be nice it if the sub would embarrass the VTF3-MKII).
I'd do the TC 2000 15" svc in 320 effective liters with a 6" port that is 27-28" long and feed it with a Buttkicker amp. It's a solid design and a few around here have already built one - they can chime in about their results and associated equipment. I think you would be very pleasantly surprised. It's easy to do around here, but please don't let the talk of multiple large LLT subs or 16 driver IBs water down the performance capability of a single solid LLT in your mind ;) Some of us are just a little crazy. In my own case, three Avalanche 18 LLTs will far, far outshadow the rest of my system, but the total cost was so relatively low (same range as a single SVS Plus/2) that it just made sense.

But, lets just say for the time being I set my budget at $800 (new or used), any good suggestions then?

Add Crown CE4000 to the list. It's unlike the CE1000 or CE2000, it's
BCA with switchmode powersupply and PFC. The auction site shows a B stock for
$800. Go to the pro forum and get more opinion, but from what I recall, many
people liked the CE4000. This might be a better snag than K2 to drive the
monster woofer.

I forgot to mention this amp as it's also in the binks test. Here are the results.

It's PFC so sagging AC line doesn't really affect the power output -> sweet.

*****************************
CE4000
20hz - 967w per channel, 4 ohms.
1khz - 1221w per channel, 4 ohms.
20khz - 630w per channel, 4 ohms.

..... vs. .....

K2

20hz - 724w per channel, 4 ohms.
1khz - 848w per channel, 4 ohms.
20khz - 1490w per channel, 4 ohms.

K2 with sagging AC line
20hz - 446w per channel, 4 ohms. <<< red flag
1khz - 562w per channel, 4 ohms.
20khz - 1285 per channel, 4 ohms.

*****************************

You will have sagging AC line, at least 10VAC, maybe 15VAC
unless you wired up your home with heavy awg wire, 8 awg or less.
I get 10VAC drop with 8 awg and over 20VAC drop with normal house
wiring and my PLX amps don't operate under heavy stress, they shutdown.
Strong AC line is important.

CE4000 for sub seems to be a sweet choice as their is potential
to get 2x more power vs. K2 if your AC line sags, which it will....

As some of you have suggested, I will keep a look out for the amp but will not necessarily worry about it now.

Steve Callas - sincere thanks for making me question whether or not I should go the the LMS5400 (*jk sarcastically)

I am hoping now others would chime in and either support going for the LMS5400 or discourage it. Maybe I am just looking for someone else to blame for either going or not going for the 5400 (should one choice prove better than the other)...

If others concur that the 5400 sonosub project should be abandoned..so be it. On the otherhand, knowing that I am willing to spend a little money, if you think I should just go with 5400, please also let me know.

Thanks for you help guys...I could always use the backing of the "brotherhood" should I go for my first DIY sub.

It depends on what you want. If you make a lower cost sonosub and later you
desire more, then you will need to build another or upgrade. If you can afford
the single monster with a beefy amp, you may be happy for a long time without
worries. On the other hand, you can make a subwoofer array using low
cost woofers that can do some amazing damage to your house, but this will
imply that you may need a bigger enclosure than the single monster sonosub,
so analyze your real estate issues. Can you afford to install many low cost
subwoofers ? My house is small so I would seek one woofer of mass destruction.
If my house was huge, I'd make an array using cheaper woofers, but you may
need to buy more amplifiers too. Also, what if you sell your house? It would be
easier to transport a single sonsub vs. an array.

No man, do the 5400 sonosub! You could be able to brag that you have the best single driver sonosub around. Who cares if your speakers are mid-level, you can upgrade them in the future!

Do it, there is no reason to really avoid it (money aside).

If you are interested in having MULTIPLE of these gigantic subs everywhere, then you can save some moeny and "maybe" get a better sub. But for the one and only subwoofer ... this is your driver.

thylantyr, the goal is definitely a single sonosub, I would consider multiple should it prove much much cheaper and comparable performance. But I willing to pay a little premium for 1)building convenience (building one as oppose to many)
2) aesthetic purposes.

Personally speaking, I would love to have a killer sub in a single enclosure. If I could get away with it, then nothing like it. Now, what I will put in that single enclosure is up for debate.

P.S. thanks for casting your vote to those who did, much appreciated.

If you want the best single sonosub you can build, the LMS 5400 is your driver. Its that simple.

If you don't mind building multiples, then I'd go with the TC-2000.

I think what many be even more difficult than deciding which one to buy is actually obtaining one.

I am having trouble getting in touch with anyone of the sales rep at TCsounds. Anyone knows when the LMS5400 is going to be available or actually start shipping.

I am surprised you can't get in touch with anyone. They should be at the office.

I suspect the 5400 will be out before the end of the month, but I dunno. Last time I checked they were waiting on the titanium cones.

you wont be able to get in touch with anyone since they are on their way to CES if not there already... dont sweat it.

Ah, I forgot about CES.

But yeah, the 5400s aren't out yet anyway.

another thing to consider is that the crown k2 has a very high damping rate which helps control the driver, and seems to get overlooked. with these big drivers , more control of the cone should be considered. no?
also used k2's routinely sell for 600-800 on e-bay.

Kinda off topic but, I was thinking about buying this same driver when it becomes available but have a few questions. Obviously its going to take a very good amp with 2000-3000 watts to do it justice. Now with these powerful amps can they be run off a regular outlet, or would you need to run a dedicated 20amp line? I rent a house so adding a new line is pretty much out of the question. My big screen & receiver are all plugged into the same outlet & the outlet I would use for the amp would be on the same line as well. Would this cause me to trip the breaker everytime a tripod emerged or a cannon blast went off?

Yeah...that would be a bad idea/setup.

Extra DF doesn't bring anything more to the party.

Running woofer(s) vs. mains will cause the amplifier to work harder. You will
get voltage drops on the AC line. When this happens, many amplifiers will output less
power, you may not notice it though. If the AC line voltage is too low, some amps shut off
and you may wonder what happened? If I plug my PLX3402 into an ordinary outlet with
20A breaker and play test tones with a resistive load, my AC line sags under 100VAC
and the amp turns off in seconds. The same scenario playing music on my non-woofer
speakers {the mains}, no problems. The best way is to try it first to identify a problem,
if one occurs, you fix it. If you were in process of building a new sound room and the
electrical was going to be installed, then of course you want to over-engineer the electrical
system. I'd over-spec the wiring and use at least 8 awg romex for a 20A outlet to ensure
minimal voltage drops. If you were going to install many proamps, I'd install a subpanel
in the room and run 2 awg. Overkill is sweet. Why would one spend big coin
on proamps and have the power sabotaged because your electrical wiring is
whimpy and you lose output power? You spend the big coin to get high power
so spend a few extra dollars and have some fat wiring installed. If you talk
to electricians, many if not all of them won't understand this idea and think
yer nuts.

I spoke to Heather at TCSounds yesterday.

They expect the parts of the 5400 to arrive from "out of country" in two weeks. The lady mentioned that they will be immediately assesmbeled and shipped; however, she added that "we are not making any promises".

Just though I let you guys know.

"we are not making any promises"
:D Hopefully that's strictly in regards to the shipping....

just FYI....heather is pretty unreliable! Deon and Kyle will give you real timeframes, etc, but heather is just a waste quite frankly!

I'll be honest, I doubt if they ship anytime in January....I'll see Deon at CES next week, and I may get some straight answers for ya.

Hey! Heather is a nice lady, don't put her down. :mad:


:D

:D
couldn't tell you if she is nice or not....never dated her :p

but as far as her work..... :eek: :rolleyes: :(






:D

I had *someone (*sorry I am bad with names) from TCSounds contact me again regarding the LMS-5400. - This time it was a male's voice so I know its not Heather (Disclaimer: not like I have anything against her). The person said that the titanium drivers are to arrive from china this upcoming tuesday. They project to have all orders built and shipped by this upcoming friday.
