Am looking to sort out a disaster of sound thanks to a Heath Robinson set up of active speakers (formerly used in an old cinema, and now on their last legs....) Fronts need to be no more than 50cm tall and will go in existing wall cavities behind the screen. Rears to be wall mounted, possibly dipoles? The lot will be hooked up to a Marantz AV 7005 for processing duties for movies and music. Room size around 25m2. Am looking at PMC, ATC or Dynaudio Air...... Any advice would be greatly appreciated! Happy New Year!
