hi, it sounds to me that your simply over driving the sl3, if you have balanced on your front and single ended on center and rears , you have 6db more output of gain versus the single ende d. plus if you added 6 db of gain on the front thats a total of 12 db or 4 times the power versus the other speakers. power doubles for every 3 db loudness example sl3 4 ohm load requires 2watts for90db 4watts 93db 8 is 96 ,16 is 99 ,32 is102, 64 is105db plus you need in reserve a ten times amount of power not to clip the signal on dynamic peaks. example 8average watts 80 on peaks. on your loud music 32avg 320 peak 64avg 640peak, you can see how quickly you can use all that power for a small increase in volume. hope this helps you understand power versus loudness.
Help with speakers Martin Logan SL3
I have a set of ML SL3's. These speakers contain a 10" bass driver. I have been reading several responses about these speakers and am confused.
I am using a California Audio Labs CL-2500 (500x5) amplifier of which 50 watts operates in class "A".
The speakers can handle up to 200 watts. When I crank
the volume up, maybe a classical or jazz piece, the amplfier clips! Here is the kicker. My preamp is a CLASSE
SSP-50 and when I run it in 5 channel stereo (which includes the ML Logos and Scripts) ONLY the two front channels clip. Is it strange the two front channels are being run to my preamp through balanced cables while the others are not?
Any ideas/suggestions/help?
