Had an idea for a sub that would "hide" behind your couch. Wedge shaped and 5+ feet long. It would have multiple drivers (say 4 Infinity 1260W's) and they would fire into the backs of the people sitting on the couch. Thinking that since it was so close to the viewers, it would have a nice viceral impact and perhaps be less effected by room mode (or not, who knows?).

Bonus would be that it woudn't be terribly hard to make, wouldn't take up a lot of room, and could have a decent WAF.

Is this a good idea- has anyone done it?

A couch won't impede bass, so from that standpoint it's OK. As for room nulls, you can calculate them pretty easily using this:

Keep in mind with that placement you'll have reflections from not only the front and side walls but also the ceiling.

Only issue I can imagine is that when an explosion happens in front of you, the impact would be from your back....

Sounds like the box I built for my truck when I was younger. I just built 2 ported boxes with the1260w and have been pleasantly surprised with there performance.

My sub's in back of me, and you can't tell the difference. The pressure wave travels at 1130 feet per second, so you can't tell which direction it originated from so long as there are boundaries in the room reflecting it back at you from every direction for all intents and purposes simultaneously.

+1 Back in 1997 I had three JL 10W6's (the original ones) in a dodge dakota extended cab firing towards the drivers and passengers seat. Let me just say they hit you hard in the back. It was an awsome experience that I'll never forget.

My subs are also in the back, properly setup, you can't tell at all.

Sounds like a good idea.

I'm using aura bass shakers though.
