Dreaded wall unit

In order to purchase my stereo equipment I had to make an agreement with my wife. Stereo stuff is find as long as it can not be seen. I had a really nice wall unit made to order using my equipment dimensions to dictate design. Here is my quandry. The speaker monitors are inside an enclosure. The speaker mesh covers are removed and the face of the speakers are 1 inch behind custom speaker mesh plates that are attached to the face of the cabnet. Would lining the speaker enclosure with sound absorbing material make any difference in sound quality? If so what would I use? I was looking at Dynamat but it is designed for cars,is quite expensive,and looks lke aluminum foil. Any suggestions aside from removing the wall unit would be appreciated

It would be a lot better if you could bring the speakers out 1 inch to make them even with the front.This is causing a sound imaging problem.I don't know if yours could be front mounted like a regular speaker.That Dynamat material may be mostly for thin metal that a car is made of to get rid of the tinny metal resonance if its what I think it is.If the cabinet is thin and vibrating away,something like that may damping it some.There are speaker filler materials(the filling in pillows looks and feels real similar))that could dampen bass resonance problems. Fiberglass is used too,but not user friendly.I think moving the speakers out 1 inch for starters if possible would sound more open and natural.Here is the filler material link.>>[http://www.parts-express.com/pe/showdetl.cfm?Partnumber=260-330]

I agree with Hifitime that the front of your speakers should be at least equal to the edge of your cabinet. If not you will get reflections off the edges that will distort the sound.

I have a similar deal in my family room. I use floorstanders, but made 2 modifications to a wall unit which otherwise - I suspect - is pretty similar to yours.

1) I hinged the face of the portion of the wall unit that is directly in front of the speaker (i.e., it is now a pair of doors).

2) I put the speakers on a pair of "slide out" platforms - similar in concept to the mechanism on which your dresser drawers ride.

For more critical listening (rare on this system), I open the doors and slide the speakers forward app. 1 1/2 feet.

You might do something similar (like a telescoping arm), especially if the bottom of your monitors allow a screw in support for stability.

Good Luck
