Thanks for clarifying!

But check out the ZV4. If you want small sealed cabs and silly bass (12) zv4 18" would be almost impossible to beat.
LMS is nice if you can find them.
I'll actually need small drivers for my balancing subs on the sidewalks....I couldn't find the zv4 on the Stereo Integrity website....is this a word of mouth product from them?

smooth frequency response (though eq would be needed to make it flat).
less than a db of compression until the amp went into clipping.
very low distortion.
6" split wound coils and a crap ton of neodymium give these things crazy horsepower. but good design and some other tricks may them quite linear.
unlike most of the high excursion subs, they have relatively good efficiency on the top end, so if that is important for high spl music, then they may be worth taking a look at.
street price is around $750 I think.
That looks pretty cool. Is there a strategic reason to use an undersized cabinet? I'm brand new to this, so I want to learn as much as I can.

Jay, I have no idea what most of that means. Lol.

Others can be considered as well and multiples of any lesser driver can and should be considered, always.
Thanks Scott! Thanks for this list...so should this be considered a top-down hierarchical order of performance?

Just grabbing some drivers and throwing power at them will work but you could have tons of output left on the table without knowing what you "could" have done.
Believe me, that is something you don't want to deal with.
Just a quick example, you buy 2 lms 18's, put them in 3 CF boxes, great, sounds awesome. Wait, I could have fit 2 x G-horns in my room and with the same 2 drivers had 4 times the output.... oops lol It's stuff like that you have to figure out before hand.
Great point! What's a g-horn? The cabinet can be about 30" deep, max and can be as wide as it needs to be. Height....not really limited, but I am using a baffle wall around my triad cinemaplus Platinums, which are pretty tall, so I may have some height constraints, now that I think about it.

Great info....is this the general consensus? For the Stereo Integrity 18, are you referring to the HT or HTS model as being equivalent to a Dayton (is "Ho" the Dayton model name?)
Ah, I will investigate right now. Thank you!

[/LIST]So, set means what exactly? 2? 4? 8?
From your post, I gather that you want the absolute best. However, I recall seeing other posts, in the not too distant past, where you have mentioned cost being a concern. Just keep in mind that most potential short comings of one or two drivers can be overcome when you start talking multiples (4, 8, ect...).
While listening at reference, will you be able to tell the difference at 4% distortion using 8 lesser 18" drivers vs 2% distortion using 8 superior drivers? And the answer is...
Also, I personally feel it would behoove you to make nearfield placement a top priority... One 18" firing directly in your back will have more of a palpable impact than 8 18's accross your front stage.
What was the last all DIY sub theater that you demo'd? @Gorilla83
's right? Did you enjoy? I am assuming that your primary point of reference, right? Or have you demo'd any other similarily capable DIY sub systems lately?
Good luck with whatever you decide to go with. Always happy to see another DIY convert!
By set, I mean one high end, top performing driver with 24" diameter and one with 18" diameter. Once those are identified, I can add multiples of each. Near field isn't too much of a concern for me, as I use Crowson bass shakers. Plus, the room was very carefully engineered, and subwoofer placement is already finalized. I've never demoed a DIY sub before...but I'm in bed sick...I may have at a G2G and just can't remember.

I believe this is a sign of a superior design, and nothing(that I have seen), even comes close.
Check out data-bass.com and look at the multi-series charts that show distortion at varying sweep levels. Compare it to the HST-18 and XXX-18...just be sure to compare the same sweep levels as they are colored differently.
In fact, look at the 115 and 120 dB sweeps for the LMS5400. Compare it with any driver that has been tested on data-bass.
Ah....this is EXACTLY what will help me decide. Thank you, sir!!! Will do comparisons today!

For large drivers I like value so I would buy what the best value I can. So while the SI is best value I do like the upper end woofers. If money was no object and I had LOTS of space I would love to have a bunch of BC 21 SW152's sealed. Or RCF 21 N551's. Also SI 24's would be nice also.
There are so many options out there that if you can fit anything and have the money to buy anything it really comes down to buying what works best for your taste and wants. Lots of good drivers out there to choose from.
I will give all of those a look. Thank you!!

The room is 16'8" wide x 28'6" long. Will definitely be using a multiple subwoofer solution.
