Anybody use RythmikAudio sub kits?

I have one of their servo subs in a 2.1f^3 cab in a 2.1 music system. For music I do not believe you can do better in it's price point, or up to around $1000.00. This thing really sings, low extension and very defined.

For HT I really have no experience, but I would bet that with your room size, it would be more than adequate.

Hope this helps😀

I have one sealed servosub built, another on the way, to be used as a stereo bass section. If you give them the kind of enclosure they deserve (over-braced baltic birch or marine ply, possibly doubled baffle), I think you'd need something like a huge infinite baffle to beat them in terms of pure sound quality for music, and even then, with a few caveats. The TC sounds drivers are already top notch, adding the servo system takes them to another level IMHO. For high output home theater use, there are probably better values out there, though the selectable extension/damping switches allow you to trade off some extension for surprisingly high output. Still, there's no way around the laws of physics, you will not get more output out of the servosubs than another 12" driver with similar displacement capabilites in a sealed box. The output you do get will be cleaner though, especially at high volumes.

FWIW, my enclosures are ~ 2 cu ft, so the size you are thinking will work fine. I haven't played with stuffing yet, but probably will add some when I do the finishing on the cabinets. I went with 1.5" front, back and top walls, baltic birch ply all around. For the sides and bottom I used .75" , with 1/4" thick 12" x 12" ceramic tiles glued to the inner side/bottom walls, and a shelf brace about 2/3 of the way down the driver cutout. These boxes are incredibly rigid, dead, and heavy. IMHO, the caliber of driver and electronics deserve this kind of construction, and it costs only about $10-20 more per box, plus a little more time. Better to overbuild than underbuild IMO, especially when it costs so little.

Finally, that square room is going to be hell for standing waves... I would plan on investing in some room treatments and/or low frequency parametric EQ as well.
