I am currently remodeling my basement. In so doing, I am building a wall in which I would like to install surround speakers. However, instead of purchasing new In-wall speakers, I would like to use my JBL bookshelves. I guess what I will do is create a recessed "shelf" in the wall and have my speakers sit on these. Then, I would like to cover this recessed shelf with a grill that is flush to the rest of the wall. Does anyone know of where I can get a grill that I can mount flush to the wall like this? Is there another solution to what I am trying to do? Thanks.
