Your theater is 3200sqft, WHAT?
Your house must be 20,000sq ft on 20 acres I'm guessing.
That sounds like a barn, rather than a room. Let me guess, the ceiling is more than 10ft as well wink.gif

If you sit directly on the subwoofers... you might be able to reach 5db. LOL wink.gif

You're gonna need 16 Dayton's in that room, and 8 EP2500's, minimum.

I sure hope you have an IMAX screen in that room to go with. biggrin.gif

So, I've been contemplating this a lot, and something that keeps popping into my head is just using a Sonotube.

The Sonotube calc software says the sub will work fine in a downward firing config.

My options locally for Sonotubes are either 20" or 24" diameter. 20" would have to be over 5' tall, but 24" would be just over 3, which is much better. Now, the real question is the port. With a 24" Sonotube, a 10" port's velocity with 1000w is maxed at 16.5 m/s. However, that requires that the enclosure be larger than modeled by WinISD (11.2 cu ft vs 9.3 "ideal"). Would I be able to add acoustafill to reduce the volume and keep the port?

An 8" port means the sub wouldn't need to be as tall, but port velocity rises to 25 m/s.

The actual viewing area is much smaller than that. I just included the total dimensions of the room because there's no way to enclose the theater. As long as it's plainly audible in the viewing area, that's all I care about.
