In all cases they weren't being pushed to their limit. I wouldn't say they were loafing along, but definitely not near redline.

The setups that were compared were my 4 LMS's, NB67's 2 dual opposed Dayton's AND dual SubM HP's, and mjaudio's setup which has like 22 subwoofers. He has/had a mixture of 10's, 12's, some Dayton's, some SI's, and a Mal 21, off the top of my head I think that's it. lol

An observation here about the recent discussion of room sizes and reference and different MV listening levels for movies. I recently stated we averaged probably -17 on movies. Thats with creeping to -19 or -20 at times it was extremely loud on some movies if needed. I bought a Ben Q 1070 projector to "get aquatinted" and try out DLP technology. Future PJ is undecided. Certainly lots of fun and a huge viewing size is much better. We have a screen coming on Wednesday, sorry guys I did not opt for AT. I know I know, probably regret it...But my center CD sits collarbone height right now as I type. I could have got the AT from same company for a tiny bit more but wasn't sure about the weave. Could of done Falcon material but honestly I buckled to the ease of already done. I plan on attaching a couple pieces of 1x3's (guess at this point) or something vertically. Then attaching the brackets that are made to bolt to the TV to the wood and hanging the screen on the neck/TV mount bracket system of the stand. So instead of picking up the tv and hanging on the mount it will be a 100 inch screen Sitting distance is 9ft Anyways we have watched 4-5 movies and the least loudest has been -14 and up to -8 on the MV. My only guess here is that the glass surface of my Panasonic plasma was causing reflections. Just a white sheet hanging now from the ceiling in front of the TV. Not much absorption but it's my only logical guess. Anyway...the last few posts have me wondering about selling dual 2400 Submersives about a yr old pair and going for the JBrown ported special!!! and then some!

I ran out of gas this weekend and concentrated on getting them setup as surrounds and did not do a comparison. I can say that the 8's sound fantastic with MC music and I think they would do a great job as LCR speakers in just about any space. The 12LF's have an extension and SPL advantage but with good subs and in most rooms, I'm thinking they would be comparable. More great speakers from JTR.

I have the 8's on top of my GIK Pillar Traps but this is a temp setup as I will be wall mounting them.

Yep I can agree Maybe not the dream speaker and doesn't have the Noesis addictiveness but a solid solid speaker with zero distortion and phenomenal dynamic capability.

Would someone list like the top sub drivers available for DIY. Unanimous number one would be LMS 5400 yes? 2nd, 3rd, 4th, 5th, 6th, 7th...

The problem is the magnetic distortion field from all those subwoofers. The sub with the biggest magnet sounds best and all of the others distort due to the big boy magnets being too close. This magnetic distortion field is closely related to the gravity distortion field...you can learn more about it on Wikipedia.

I'd say the SI HS24 is hands down the biggest, baddest, best sounding sub I've heard. When we were at Beast's GTG, it bested a pair of my LMS 5400s and we couldn't tell a difference A/Bing them (level matched) until the audio went below 10Hz, which is when the LMS-5400s ran out of gas. Now that was when I only had 2400w on each of my LMS-5400s. I have 4000w now so a pair of LMS-5400s would be a closer fight to the HS24 but I'd probably still give the nod to the HS24, if only below 15Hz. Even better, the HS24 is only $80 more than the LMS-5400 shipped ($999+$5shipping). So if you've got the room, I'd get a pair of HS24s and call the sub system done. Maybe an extra 18 in the back to even out bass response.

Now I haven't listened to the UXL-18 enough to have an opinion on it yet. I'll probably get the pair back from my dad, which would allow me to put the LMS-5400 against the UXL-18 and SI HST-18, which would be a heck of a shootout. All I'd be missing is the new Dayton Ultimax from the big boy DIY 18s. Hmmm....

The FTW-21 should also be thrown in but I haven't heard it so I don't know much about it.

So here's a top 5(or so) in terms of output of the most popular DIY drivers that I've seen.
1. SI HS24
2. FTW-21
3. SI HST-18
3. LMS-5400
3. UXL-18
3/6? Dayton Ultimax 18
7. SI18 in multiples

I guess the XXX is back and available but I haven't heard if its the same beast it once was or if it has changed. Regarding throwing that bad boy in, the only thing getting thrown would be my back if we're talking the XXX. I guess the XXX must be considered but it requires such a big box for ported or infinite baffle that I've never really given it much thought. But it likely works for someone.

Haha! Did you just mention XXX's and big boxes in the same post??

What size box does the SI 24 need again??

Ok, also I have a "flare" for cost effectiveness. Don't get me wrong. A pair of 24's would be sweet! But they need HUGE 10-15ft sealed boxes. Can be done but...I like the performance I get with the dual Submersives for their size. But it would be cool to look at 24's!!! I really like JBrowns build. Thinking a ported setup perhaps...Was Dayton releasing the new 18?

Okay, so since you're talking about ported there's probably no point in considering the SI 24 or even the FTW-21 because both of those drivers require pretty large cabinets. So if we're talking strictly 18's I would rank them like this.


1. LMS-U 5400 ...$925ea.
2. Funk Audio TSAD18v1 driver ...$850ea
3. iST UXL-18 ...$550.00ea
4. SI HST-18, I would probably rate this driver above the UXL-18 but there isn't much feed back on it and pricing hasn't been released. So for now until its a little more proven I'd still rate the UXL-18 higher.
5. Daytona UM18-22 ...$279ea, again this one hasn't been out very long but I already know that Mark Seaton has vouched for it so it's safe to say it must be decent.
6. SI HT18 ...$179ea
7. iST IXL-18 ...$350ea, I'm willing to bet that this would out perform the SI 18 and perform every bit as good as the UM18-22. But for guys south of the border it doesn't really make sense to buy it. But for guys in Canada they'd almost be crazy not too once you factor in cross boarder shipping taxes and currency exchange rate its the same price as the SI 18 and UM18-22.
8. Daytona RSS460HO ...$249.


I know that the stuff from RE Audio is good too but you just don't see it being used as much.

David,

WTF? Is this a joke?

How are you going to throw something like this out with no backup info or links? What is your physics background? The "biggest" magnet doesn't necessarily mean "strongest" magnet. Is size the issue, or is a stronger magnetic field the issue?

Did a wiki search of magnetic distortion field and was able to find this. While I'm not one to dismiss the theory that you proposed, how the hell can you say that magnetic distortion field is altering the performance of anything in anyone's system? Have you even seen @mjaudio system? Or are you just saying that he has so many damn (different) subs that all of the different magnets are fighting each other? How close do magnets have to be to each other for this "distortion" to occur?

Lame post man... You kinda left the science out of your response.

Again, I'm not one to argue with you because I have no idea if/how the "magnetic distortion field" and the "gravity distortion field" effect a drivers performance...my issue is that I don't think you do either.

So either educate us...or leave that extremely technical conjecture at home.



Unless you were just joking with us...In that case I say... You got me!!!

HAHA. That so rarely happens. :PATSBACK:

But you have a nicer system than I do...or you did. Not sure what you actually took over there. And you have/had a nicer ride than I have so I think Austin might have a few more points on the scoreboard.

But give me another month or so and I'll be putting up more points on the scoreboard. SHHH.

I had a weird thing happen this weekend. I had some friends over and gave up the sweetspot seats to some friends to watch a movie. The wife and I sat in the back row and immediately notice that the surrounds were very loud while the dialog was far less intelligible. Basically I sat though the entire movie uncomfortable with the sound. Yesterday, I checked the speaker levels and the surround levels were off by up to 9 db hot

I looked at the amps and noticed the gains were set to different levels on the surround amps. I re-set them to the "usual" position and everything fell into place. I have no idea (other than teenagers) how they were moved but that it is clearly something that I need to watch for in the future. Makes a case for amps without adjustable gains ...

Yeah that stinks when that happens RMK! Stuff like that has happened to me before too - something is off, and you only discover it later.

Yeah, the couple had been over before for movies but had not heard the system since the 215RT's. Their discussion on the way home probably went like; wife " wow I didn't think that sounded good, did you? ... husband "really? I thought it sounded great!, I've been thinking we should do something similar" ...

So it goes ...

Yea, that bites.

Put some tape over them and they're far less likely to get played with. It may be a case for no gain adjustment on the amps...but a really poor one .

I think its a bit early to throw the HST18 in the list, as barely anyone has them and there arent many in the wild that have been tested.
The si24 is for sure the leader in pure performance, SQ is subjective so IMO that should be a moot point for any driver but Dgages list is pretty damn close.

Lots of options for everyone!

3. The commercial subs cost how much?
4. I bought the LMS-5400 uber subs and heard a few SI18s for 1/3 the cost (2 SI18s to 1 LMS-5400) and I can't tell a sound quality difference. Are you *#&*#)@& kidding me?
5. Good subs should sound similar when EQd similarly...output level at certain frequencies is usually the differentiator, which is why many have so many multiples.
6. As DoubleWing mentioned, you want to spread out your subs around the room as a start for measuring. Middle of each wall in a room might be a good start and then move subs to determine where they fit best in YOUR room.
7. Usually paying more for amps will get you better quality...be careful, many pro amps are LOUD. May or may not affect your situation.
8. I LEARNED A TON ABOUT AUDIO AND ACOUSTICS DOING DIY SUBS AND STILL HAVE A TON MORE TO LEARN.

Is it the room?? The setup?? Who knows?? So take it for what it's worth. lol
One last comment on this to back up my homie edogg.

NB67 (chayne) and I both agree that the quad LMS Ultra's do sound different then our systems in that there is more detail to the bass. I win the war on SPL and shake factor which is greatly helped by having the system on the second floor. It is probably a tie with Chayne though now that he has added a pair of dual opposed 18" daytons to his Submersive pair but he is on a slab. I think Chaynes new house will have the media room on the second floor so I have to step my game up

I had a pair of sealed LMS Ultra's before and sold them because I wanted more SPL and was a little bummed these expensive drivers didn't give me what I wanted. When edogg added another pair to his set-up to make it quads that's when I had a DOH moment, I wish I would have kept my pair and added another pair. It was a big difference in edogg's system when adding the second pair of LMS, a lot more than I was expecting.

Only you would hear that. Unless your friends are audio nuts like all of us, my thought is that they thought it was awesome. Early on my 4520 changed settings a couple of times. I remember one time my theater sounded horrible and went in and everything was reset? It has been fine lately.
