(3)Are these speakers can be used in the W15'xD13'xH8' lving room of the apartement? And how long be the distances from the rear wall must in this case?
(4) Are the Revel F30s well matched with the Krell 300iL and the Arcam FMJ CD23T?(listening music:Classic) And are these speakers driven at 100% in this case?
