Design for an infinite baffle in wall
« on: 20 Dec 2006, 02:27 am »
Hi Danny,

My wife wants the floorstanders out of the living room, so I promised I'd try to rebuild our fireplace surround to incorporate an in-wall system. The fireplace wall is in the corner of the room, about 8' across. There's about 75 cubic feet of space behind the wall, so the entire wall would be the baffle. I will be tearing everything down except the framing studs, so I'm free to do what needs to be done, but the drivers need to occupy as little space as possible, so I'd like to make it a 2 way with a 6.5" maximum driver size. The room itself is 17 x 25 with 8' ceilings. An array might even be a consideration if we can keep the midbass drivers small.

Can a system be designed with appropriate crossover integration for an infinite baffle without measuring for the cubic footage? Achieving the lowest bass is not a priority - clarity, speed, and transparency is.
I'm not that concerned about imaging and soundstage - I realize that's hard to achieve with an in-wall arrangement, but I would still like it to sound as musical and resolving as possible.

Do you have any thoughts, Danny, and could you design something for me?

Thanks for listening!

Actually I have something along these lines in the works for a new company.

How about an on-wall design that only sticks out about 5 or 6 inches and has no interaction with the wall? It might let you keep great imaging and sound stage as well.  aa

Gee, that was a fast response - what do you do for fun?  :icon_lol:

Sticking out from the wall probably won't fly with my wife. She wants them as indistinguishable as possible. I will probably even have to build a removable paneled door to cover them when not in use.

PS: here's a photo to give you a better idea:


I plan to extend the wall on both sides with additional paneling.
