Hello. New to this forum. I recently purchased a Marantz 6004 amp/cd combo and a pair of Monitor Audio BX5. First impressions are not good I'm afraid. The BX5's sound so rough and disorganized. Speaker cables are AQ FLX 14/4 and IC are AQ G snakes. I made an AB comparison with a pair of cheap bookshelf speakers and the sound was spot on. The room in which the equipment is set is 20 by 15 feet with 11 feet ceiling. Very reflective room. Finally the BX5's sound so bassheavy for such a small tower. Plugged the ports and became more punchy but still low frequencies dominate. Are these speakers correct for the Marantz combo? Thanks in advance!
