I have been thinking of selling my M80s for a set of the inwalls just because I have to keep them so close to the wall all the time. I came to the conclusion a nice box built to my own tastes, well my wife's, should be realatively simple or as hard as I want(curved wood anyone?) and I could then stain it to match the new house trim.
