So I am putting 2-4 XXX 18s and porting it to 10hz. My room is 1400 plus cubes. Start from there. I want to try the ported XXX as it measured very well in that large enclosure. Mine is even bigger hence the lower tune. I am starting my line array build too. I know the dual DTS-10s were plenty in my room up to 12 dB hot and dual XXX ported is even stronger(not midbass).
If I was smart and not amp/voltage limited I would do the same as long as Walter OK'd it since my room is over 6,300 cubes! But being that I have as much power available as I do, buying more amps and sealed Seaton stacks will get me where I'm wanting to go, why not lol. But it will cost a lot more for the sub 10hz range I love so much. I still haven't chosen which amps to use for all the subs since I'm in search of the lowest roll off possible in a 220v 10,000 watt+ housing.
Since I have two rows on the resonator platforms it's even more golden and can easily add a very short platform for the front row that's on slab if really want but even sitting there now provides great tactile feedback directly on the carpet. I only watch 3D movies in the front row too so not overly concerned about that anyway.
In my smaller room (yet to be designed or constructed) that will be dedicated for 1-3 people gaming/movies the walls will be constructed so that the openings for horn loaded or vented cabs will be flush with the rest of the side walls for a DBA from side wall to side wall. They will be stacked and flown overhead as well for XXX near field fill in "if" OK'd by designer since have access above for such an arrangement. I don't know if I can increase the ceiling height from 10' in the entire room yet as there are stringers tied into LVLs as ceiling/attic joists. BUT I will tie in either an IB SBA/DBA or Rotary sub to keep the ULF alive like I originally wanted to do in the 6,300cuft theater room. This will just be much easier and will pay off since I watch a lot of movies by myself (wife can't stand scary movies) so can design around the largest OLED or LED set affordable since the space will be so small. Acoustic plan is DIY deep skylines for 100% coverage of useable wall space. Right now I have aproximately 22'x16'x10' of space to totally do room within a room construction but could gain more when add the new garages so way more than enough room to even use 2x12 lumber all around if needed. Hell I guess I could technically use total LVL construction or steel even though I don't have much experience with steel. But there will need to be some super strong walls to house a DBA of horn loaded cabs(thinking Orbit Shifter or similar) or vented cabs. I've seen a vented DBA but not a horn loaded one so it has me intrigued to say the least. I just don't see any way around using a DBA in such a small space and the need for extreme mid bass makes the idea that much greater, to me anyway lol. Something I've also thought about for the ULF is a SBA or DBA using the ceiling and floor but have no idea how that would integrate with the side wall DBA. I doubt I could do a SBA or DBA using the front/rear wall because of the flat panel being in the way. It's all way over my head how to integrate two similar systems and a rotary sub could be the easiest way to go so will just leave that part up to the experts for sure.
But that goes to show I still keep wanting MOAR extreme bass even after having ten 21" subs that make most tap out before reaching their maximum output. So, just depends on if you are a true basshead or not I guess. I've ruined my hearing with bass and yesterday was a perfect example of it. I asked my doctor to look into my right ear while I was there for a routine checkup because I thought I might have been getting an infection. It must have been the first time he had actually looked closely at my eardrum because it freaked him out when he saw all the little bubbles oozing off of it. He said, are these bubbles normal for you or do we need to see what's going on here. They are quite normal "now" for my right eardrum and my wife (a physician) freaked out when she saw them the first time. It's all fun and games but is also dangerous when exposed for too long of periods like I did when cruising country roads as a teen with 155+dbs for hours at a time each and every day while numbing brain cells too lol. So which is actually worse for our health numbing brain cells for a few hours or putting high SPL systems in our vehicles and homes? That's not for anyone but ourselves to answer unless one is under age of course. ;-)
There are limits I personally wouldn't want to expose myself to anymore now that I'm older that's for sure. I sat in a guys truck while the shop was working on my car not too long ago and his system(strictly spl) was tuned to 60hz @165db with 6 12s. That hurt and wouldn't do it again. I can take anything in the 150-160db range; although, the last few dbs-158,159,160 start to hurt in the upper frequency range 60-80hz, I wouldn't ride around and listen to it like I did as a teen. Or now that my ears are bad it could just "seem" louder and hurt a lot worse than it did back 15 years ago. For me, a nice 145-155db range is still fun for a few songs here and there and 155-160db just for demos only.
