How about this for reference. For the cost of three (3) submersives, one could have the performance of notynt.
Yeah, reading that statement again makes me think these HO's (at their current price-point) are well on their way to being the next big thing.

The LMS 5400 has less rolloff and more output down at 10hz than dual HO's by 3 dBs or so. The real kicker is 4 of these will equal one LMS 5400 in price and 4 of these will have 4 dBs more at 10hz for the same price! Yes, these are the best bang for buck out there right now. They take up much more room though needing so many to equal or surpass the LMS5400. A wall of these should do just fine!

Damn! Busted... Then the questions start to come...

I would do 4 quad opposed cabinets somewhat similar to Gorillas dimensions x 2 for each cab. I'd have to modify my center channel stand and lay the cabs on their sides, but I could make it work. Two cabs (8 subs) in front and two cabs (8 subs) behind my seats...


Have I thought about it? Extensively...

Agree on all fronts...

Walls of woofage is right up your alley MK.

Oh yeah...

One quad opposed cab per Clone channel... Perfect...

Both are very capable and will more than likely satisfy even the most die hard bass fan. Both should sound incredible. They are different though. It would cost less than $2,000 for eight Dayton drivers and for most people four XXX18's would run ~$3,000. The XXX18's are the superior driver down low with some mechanical headroom left on the table. The Daytons, not so much but these are modelled within reason and should sound very good.
8xRS18HOvs4xXXX18.gif

Ok, all things considered with the exception of space, the headroom up top you would get from these HO's is unreal. The area where the RE starts to head back down is a problem for me as it really sucks up some amp power at that point. Wanna talk about real power concerns...I already have them with just a pair on a single FP, and that is also crossed at 60hz. The 40-60hz by itself really sucks the juice away. when running at 40hz and down, there is no problem at all smile.gif

Couple questions:

Are they able to create wind similar to the caps and FV15?

How inert are the boxes? End-table worthy?

The "wind" is from the port. No sealed sub will be able to reproduce the same effect.

Cabinet should be as inert as any other dual opposed cabinet... Perfectly.

Yes, the Caps will still be a bit more efficient around tune. However, in the midbass region, xmax/excursion is not as big of a factor as is sensitivity and displacement - both were/are being fed the same power from the Crown.
And yes the JTR does also have a lot of headroom in the midbass area, and they also sound great. The Daytons are pretty awesome though from what I've heard so far.
Are you visiting you're in laws over the holidays? biggrin.gif
Thanks for the complements, much appreciated. Here are my building costs - some money could be saved like primer, magnets, grills, etc if you did not want that stuff.
4 X Dayton 18 HO drivers - 933
4 sheets 4x8 ply, cabinet grade - 123
2 x binding post plates - 13
black screws for binding posts - 5
#10 x 1.5" spax screws for Drivers - 10
1 gallon primer - enough for probably 8 boxes - 18
3 tubes of PL premium sealant/glue - 15
1 gallon duratex - not used yet but enough for many boxes including a roller, 2 extra pads, and shipping - 72.00
Magnets for grills 40
14 pounds of polyfill from Walmart, not used yet - 42
1 X Crown XLS5000 (when it was on special with coupon) $533
1 x Minidsp with shipping $165
Wood for grill frames - approximately 10.00 for 1x4's ripped down
Cloth for speaker grill fabric - 15
Feet for enclosures - FREE thanks to my boy popalock biggrin.gif
Sandpaper = already had like 50 sheets of 120 / 150 / 320 grits, but if you need to buy this add maybe 5.00.
Wire - already had a spool of monoprice 12 gauge, but if you needed to buy I used about 12 feet overall. 5.00 maybe?
Total = $1994. Not too shabby. biggrin.gif
Subtract out the amp and EQ = 1296 including my fancy coatings and grill materials.
I think that's it.


That is very impressive. I agree with all thoughts in this thread about the HO changing DIY. Soon as I saw the driver available for that price the wheels spin and good to read about it in other threads.

Another comparo scenerio of cost (in 2010 $)
Danley DTS-10 kits x2 = 2026
EP4000 x2 = 698
BFD1124P = 99
PL glue = 30
deck screws = 55
driver screws = 14

=2922 total

and you still have to buy finish work (duratex etc)

You sir are cheating what we should call the subwoofer 2k rule biggrin.gif Maybe let's call it dB/$ ratio lol

"I should really see what dB levels I'm pushing. Long as it can't foam my beer during a movie we are ok "

I've thought about it from this angle as well. I'm thinking big picture though.

I think everyone here has seen my grandiose ambition for my ultimate bass solution:

Subwall.jpg
That would be 32 LMS-U's requiring 16 Clones.

I could modify this design to add 12" more depth to accomodate an opposed configuration, double the # of drivers to 64 and half the # of amps to 8 and still maintain the same level of performance of 32 LMS-U's.

Plus, my materials list and overall electrical needs just pretty much cut in 1/2 as well.

Just me thinking out loud...

My bad. I should have added some context.

I meant to say my grandiose "design."

That is my end goal when I have a clean slate to start with.

Awesome thread here guys! This Dayton HO18 seems to be quite the performer, and the price is an absolute steal! Gorilla83, you have inspired me and helped with the decision as to which drivers I am going to use in my soon to be started, subwoofer build. The only thing I am unsure about is whether or not to go sealed or ported. I will be powering my subs with a Behringer EP4000, then later down the road, I will purchase another EP4000.

Even though this wasn't my build, I just wanted to give props to Scott Simonian, popalock, Beastaudio, and all of the other guys who are helping to answer questions and guide us amateurs!

Yup, thanks to all the trailblazers. I was in the same dilemma as you and after a bunch of research, settled on quad 18's powered by an EP4000 (for now, lol).

That's my favorite thing about these drivers. At this price/performance point it seems to really encourage people to jump on the DIY bandwagon.

I think I might start my own build thread in advance and entitle it, "Dayton HO - The Next Big Thing for DIY Subs."

It would be my build thread / master list of everyone's HO builds. Seems like we already have 4 builds going at this current moment. Meh, pondering it...

I know it would have been cool to have a master list of all of the LMS-U builds on AVS back when I was researching.

Hey Gorilla, not sure if you have that Clone on order, but I know one channel of my amp works for sure, so if this miniGTG works out we should be able to try all 4 of your drivers on mine.

Very cool build, read through the whole thread last night and am very impressed. I am a totally newbie to DIY subwoofer builds but am handy at woodworking and am seriously thinking at making a go at this via copying your design for the dual opposed Dayton drivers and using your cutout template for the boxes (thanks for posting that).

Where I am lost is what amp (I am starting out with one sub, and will more than likely add a second down the road) to buy, and how to wire the dual opposed subs to that amp. I am thinking 4ohm load using something like this to power them?



Would this be the correct way to wire the dual opposed woofers in the box?

Also, would this amp be enough or should I be looking at something else like one of these:

http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-811

http://www.guitarcenter.com/Behringer-EP4000-EUROPOWER-Power-Amp-105331706-i1448739.gc

And then add something like the miniDSP for EQ?

"Would this be the correct way to wire the dual opposed woofers in the box?"

that is for dual voice coil subs, so no. imagine that the blue lines in the picture do not exist, that is parallel and would net 2 ohms per cabinet.

"Also, would this amp be enough or should I be looking at something else like one of these:
http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-811

And then add something like the miniDSP for EQ?"

this is where it kind of sucks because many of the lower cost amps don't provide the kind of power that the driver can take in from a wiring configuration and net load that will keep the amp happy. so, you either leave some capability on the table in the drivers or in the amps. the point where you can get a good match is the whole range of copies of the crest ca18, which is two ohm stable per channel and has 5,000 total watts output capability...marathon has one, crown has one, cerwin vega has one, etc.

Listen. It's All Good.

Glad you are enjoying the build! It's fun to get others interested in DIY. I'm totally hooked now, this stuff is totally fun and rewarding. Go for it man, we are hear to answer whatever questions you have.

Started working on the grills this afternoon. I made them a little smaller than the box itself at 24" H x 22" W. To save money I bought 1x4's and ripped them in half with my table saw. I hit the edges with a 45 degree bit on my router and did a quick sand on the edges. Voila!

Looking nice. Off topic a little bit, but is there a reason you chose not to 45 degree them on your table saw? Only reason I ask is I'm building some fabric frames for my theater and am wondering if I should 45 them on the saw or use my router.

If you take yourself too seriously expect me to do the exact opposite

Jim, you are not the first person who has had that idea. smile.gif

Gorilla could start a side business cutting speaker boxes and he would never have to buy beer again

Hey gorilla,
When you get these finished I want you to try something I just experienced. My rolloff is less than yours but when you get 8 of these(4 subs), I want you to run Tron ast reference(air battle) with the subs 6 dBs hot AND with a LP filter set at 20hz with 6 dBs of gain and a slope of 12dBs. I was pretty funny watching my friends reaction and he has heard everything I have owned. It was crazy in here and the pressure blew both of my doors open to the theater. They are pretty heavy with sound board and 4 inch thick wall treatments. I know some don't like boosted low end but when it is EQ'd flat to 5hz it just adds more tactile sensations without boominess. Of course your speakers need to keep up and the SHO-10's should be OK.

So is that uxl info in the op what you ended up for the dual opposed? I cant view it until I get home, so I have to guess. haha

Cutting a 5/8" 45 is far easier to get right with the router table. Not to mention pushing a 1.5" board through the table saw is a bit shady. cool.gif

An easy way to avoid sawing off a finger is to go with a flat pack. Far less danger there. biggrin.gif I think you would be surpsied what you could accomplish. By no means am I a skilled craftsman, I just takes a little experimentation and trial/error to learn. smile.gif

I can't imagine how anyone could/would make these by hand and turn a profit when factoring in their time. Maybe I just work too slow (likely), but it does take a considerable amount of time from plan to finish. tongue.gif It is very enjoyable though.

UXL?? Originally I was looking hard at the UXLs but wound up with the Dayton drivers.

I could give it a try even with the 4 subs to hear how it sounds? Is Tron part of the scuba steve disc? If not, I will have to pick up a copy one of these days. I have yet to apply any boost with this setup.


General note - I did a 'mockup' of the grills on the boxes and they look kind of odd to me. I'm not sure how I feel about keeping the grills, I'm still up in the air as of now. I did drill the pilot holes for the magnets, but not sure if I will wind up using them. Chances are they will look a little bit better once painted black and covered with cloth though. Hmm.

Oh I know! haha. I was referring to the link you still have in the OP, I guess all that had to do with was the uxl idea before you went this direction. regardless, what were the final box dimensions? I asked a few posts up but I guess you missed it smile.gif

Ah, my bad. Final box is 7 cubes internally (roughly) and dimensions are 23W x 25H x 28D. I'd imagine one could easily swap drivers in the same box if you wanted to. cool.gif

It is not on scuba steve, this is the air battle and I don't think it goes that low but low enough. The best part of a multiple sealed sub system is you can boost the low end but be careful running them hot because it takes lots of power for boost and hot subs. This is why I said 8 drivers which ensures enough headroom. With 4 boost is fine but running hot might not be, depends on your room.
