Is your room fully sealed? Is it made of wood/drywall or concrete ?
Yeah i have no problem hitting 20-30hz at 130-140db ... for me thats not really the issue... is below 20hz where im concerned.. and when you say sealed.. like large sealed with eq? or???? and whats DYI ? haha.. Do it Yourself? ... Yeah i only plan on playing at those levels for when i have A LOT of people over and we want to watch star wars and other movies with authority.Quote:

If you want to hit 130 db, then 3 or 4 JTR Orbital shifter will get you there. If you want the extension to 10 Hz, close off part of the space and get some sealed subwoofers or go DYI. You may need four dual 18 or 21 inch .drivers. I honestly would caution anyone from doing more than a demo scene at those levels. The enemy off something that is very good, is sometimes something better.
It seems like that might be the best route to go.... I dont want to go IB because i dont have an attic sooo...... I will definitely look at his build to see an idea...So if i go sealed... Which EQ should i go with to really boost the low end?Quote:

If you want 10 Hz or less and small, you really should be looking at sealed DIY. No commercial product out there, that isn't extremely niche, will meet your target. Since you don't have a cost issue and want to keep it small, go for LMS5400's or UXL's in a 3-4 cubic foot boxes powered by 10kW amps. The example you are looking for is NOTNYT who has done this with both sealed and ported in a fairly similar sized room. There are a few other people in this arena as well.

The room is fully sealed... Im pretty sure it is made of drywall/wood ... Yeah i KNEW I would need A LOT of displacement.... Do you think in a sealed environment with eq it will provide more output at 10hz than Low-tuned ported ? ..

You said smaller is better, LLT's at 10hz are not small. IB would be best or many sealed subs. Ricci's in room of 8 ReXXX's got him 130 dBs at 10hz. He has a big room but not sure 1000 sq feet big. The only way to do it with less drivers is that XXX ported beast. 4 of those will get you 133 dBs in comparison at 10hz.

You will need to look at Infinite Baffle systems, and a whole bunch of sealed subs, or some Thigpen Rotary s. Thigpens Rotarys are something like $20k each, but hey, you say money is not an object, and they supposedly have serious output all the way down to 3 Hz. Personally I would go with a big stack of sealed. A whole bunch of LMS Ultras in some good sized sealed enclosures will do the trick. One more thing, you can get 10 Hz without spending a huge amount, but getting clean playback at 10 Hz is another matter altogether. If you don't care about distortion, it actually won't be a very costly endeavor, however even a little bit of distortion at 10 Hz will overwhelm the fundmental, ie the distortion will be a lot louder than the 10 Hz signal. Getting low distortion 10 Hz at high SPLs will take many tens of thousands of dollars to achieve, it would be pretty cool though.
It seems the LMS ultra option is really the best way to go .... What EQ should i get to really boost the low end?Quote:

Yeah i do plan on getting in contact with Bossobass! it seems they offer the best EQ for my application, .... How come nobody mentions Pasive Radiator designs though? just curious.. It seems they have the benifits of ported w/o the long tubes for extension..

Hell yeah man ! your build looks awesome!... I honestly think i might just do LLT for better output but im still debating on what to do... How does it sound though? Any distortion? House fall apart? LOL
