I'm looking for some sub advice for an upcoming theater room.
Dedicated theater room, 22 x 15 x 9 (2,970 cu ft); perfect rectangle, flat ceiling
On the 2nd floor; standard construction drywall over wood frame
One window on right side (will be sealed off), double doors at back left corner, no other openings
Will have room treatments
Two rows of seating; main listening position ~12 ft. from front of room
10% music, TV, other
Speakers: most likely JBL Cinema -- 3677 fronts, 8350 side and rear surrounds
Receiver: Denon 4311 or similar (something with XT32)
Image: Epson projector onto AT screen
Sources: media PC, Blu-ray
I'm looking for a pair of subs for ~ $2,500 shipped.
Listen at reference level with no dynamic compression (keep up with the speakers)
Bass slam you feel in your chest like at live music concerts
No port chuffing or other bad noises
Solid output to 16Hz (lower is great)
Good accuracy for music (somewhat less important)
One major constraint -- size (one dimension only -- I'll explain)
I plan on putting one sub on the front wall, center, and the other sub at the back wall, center, for smoother response across the seats. Since the screen will be very large, the front sub will need to go behind it, but I don't want to bring the screen too far into the room. Also, at the back of the room, I plan on a platform for the 2nd row of seating. I don't want to bring the platform too far into the room either.
Because of this, I need a sub that is relatively slim (<20") in either width or depth (or both). Height is not an issue (within reason). For a front firing sub, where the driver face is slimmer than the depth, I would turn it sideways and have it firing toward the side wall. Same thing at the back of the room. Hopefully that makes sense. It needs to be a "box" style sub, no cylinders. Looks don't matter, but it needs to at least have a grille or hidden driver (because the rear sub is accessible).
Here are some subs I'm considering:
Rythmik E15 - 17" width
Rythmik F15HP - 19" width
Rythmik FV15HP - 18" width
Hsu ULS-15 - 18" cube
Hsu VTF-15H - 18" width
Power Sound Audio XS15 - 18.5" width
Power Sound Audio XV15 - 18.5" width
Please let me know what you think of these or suggest others I should consider. I'm not opposed to 12" drivers, but I feel like they might have trouble achieving my goals. Not opposed to 18" drivers either, but I don't know of one that fits the "slim" criteria. Also, I'm okay with passive boxes and outboard amp.
