I have a 1960's sideboard in my living room that has the tv on top of it. At either end (it is about 130 cm wide) there are cupboards (with a closed back). I was thinking of getting a pair of speakers to put one each in the right and left cupboards so when I want to listen to music I can open up the doors to reveal the speakers. I guess for convenience, powered + wireless speakers would be easiest. Any thoughts on how much the sound (if at all) would be affected by simply placing speakers in these cupboards. For example, should they be rear ported or not? Could also link them to my tv for some bigger sound when needed. Initially thinking of Q Acoustics BT3 or Ruark MR1's...
