Put simply i have bought an AW12 subwoofer and am already considering upgrading to a Velodyne SPL800 Ultra on the reccomendation of a dealer, so my question is with my existing setup of speakers(all listed below) should i bother to change my sub as i does match my other speakers and does (to me) sound very very good especially with films. i got that little voice in my head now after speaking to the dealer as to whether i was too hasty in settling for the Monitor Audio Apex/HD range in the first place. But as i said it does all sound vry good and my room is only 4.2m x 5.4m with 2.35m ceiling height......so what do y'all reckon??
