M-Audio SBX10
Subwoofers are desirable, even addicting because they greatly improve the sound of music but they are also not without their problems! My first setup used balanced output from my Apogee Duet 2 audio interface connected to my MBP to the SBX10 with my BX8 speakers connected to the SBX10 as recommended by the instructions.  This sounded great but when no music was playing there was a noticeable whine coming from the BX8s (the subwoofer was totally quiet). The whine is not present when the Duet is connected dir
