I am currently running B&W CM1's, a Rotel RC-1550 pre-amp, a Rotel RB-1552 power amp, a Pro-ject RPM 5.1 turntable with a SHURE M97xE cartriadge and a Marantz NA7004 network DAC which I run my Macbook through. A B&W ASW608 handles the real low end. All connected with Chord Company banana plugged speaker cables with more Chord Company quality interconnects.
Sound is fantastic at low to moderate volumes but the woofer on the CM1's makes a horrible popping / cracking sound when I turn things up louder (just under half way). It is especially noticeable on lossless playback through my iPhone via the Marantz NA7004.
I don't have the bass turned up or any equalizers (including Apples or Marantzs) in use.
If it is too much bass power being sent to the speakers is there a way I can channel the excess bass power to the sub-woofer to stop the CM1's over extending?
