in wall speakers

Anyone have experiences with inwall speakers? I have installed several pairs in my house for non critical listening and really like the conncept. I'm considering putting some in a tracking room and would like advice as to what type of mods I could do to improve their performance. What are the main drawbacks of In-walls? Is it possible to use them in conjucntion with a sub to get a nice midfield "B" set of speaker in a 1600cu\ft control room?
I installed these and like them.

The guy that doesn't like it has poor arguments.

So where goes the soffit mount speakers in all the studios!!!( same principle but different construction)

I can understand that a poorly made installation gives bad results but imagine putting speakers in a rigid/well damped wall with some excellent speakers, this could give some great results with a nice(and unobstrusive) look.

Serge,

I notice from the above post some things different with soffit mounted speakers. The speaker is not coupled to the wall, it is flush but that is it. I was listening to some inwalls last night and I did notice that the sheet rock was vibrating in a bad way. I may try cutting out sheetrock and putting in MDF. I would like some advice or opinions as to how big a piece and what I may expect to gain.

Thanks

If you are ready to put MDF isntead of drywall, that so could be possible to use the techniques for soffit and apply it to the wall or some hybrid of "half soffit", making some decoupled base from the floor(hidden stand). For shure 1/2 inch drywall is too light. Firecoat double thickness 5/8 inches(total of 1-1/4 inch) would be a compromise. MDF is better(3/4).

In any situation, structure has to be rigid with no rattle, and if you have a door in this wall, things can get worse if the door is not against neoprene sound seals. The idea is to have something dead and heavy enough to deal with the energy of the woofers.

Another possible problem is the vibrations transmitted with the help of the wall, the adjascent room would have bass in it. So a separate base that would support a speaker box, flushmounted in the wall would help and adding some fiberglass in this wall would help too.

But I'm not an expert in theese points. Maybe Barefoot could reply.
