Recessed subwoofers
« on: April 18, 2011, 10:42:34 am »

I'm working on a project for a customer and they would like all the speakers recessed in the plaster/drywall ceiling...including subwoofers.

It's an older building and the framing is 12" centers leaving about 11"-ish to mount speakers in. I'm having trouble finding a subwoofer that will fit into a cavity that narrow. I've looked at JBL, Atlas, and a few others.

Appication is BGM but a touch louder...would prefer to stay away from 70-volt, but if that's all that fits...

Any help would be appreciated.

The Tannoy CMS801sb might work (1x10" @ 6 ohms).  It requires an 11.61" cutout.
Tannoy's iw62 tS would definitely fit the bill (2x 6.5" @ 8 ohms each); cutout is 7.39" wide.

How much depth are you working with?

Re: In-wall...actually, in-ceiling. Top floor of a REALLY old commercial building.

Re: Depth...above space is the attic...so several feet.

The Tannoy units look like they might fit the bill. I'm trying to avoid custom boxes or altering the framing to fit other subs. The budget isn't there for stuff like that. I need something that allows me to cut a hole, shove the thing in, and be done with it.

Thanks for the suggestions.

Best I can come up with; still a bit big for your application.

You could always mount the subwoofers in the attic space (downfiring), and just put a grill into the ceiling right below it.

Ahh, YES. That kind of thing is done all the time. Instead of trying to defy the laws of physics (what kind of low end do you think you are going to get from a 6-1/2" driver?) you can get nearly anything up in the attic and put grills in the ceiling. Straddle a couple of bays.

I know this is done all the time...I've done it myself before. However, anything too large to fit through the 12" joist space is too big to fit through the attic access hole. Anyway...I'm not looking to re-arrange peoples' DNA...just fill in a little but below what the rest of the little recessed speakers can do.
