The current was what caught my eye on the JC1's as they listed something like 135 amps for instantaneous peaks.
The W4S is rated at 40 amps. I also see that an older Krell FPB 300c was rated less than that.
Now , of course, I am not sure how to read and understand all this technical data and be able to compare continuous versus peak outputs.
However, you cannot have current without watts, so I suspect that alternatives to the W4S will be different in the higher frequency and not so much in the bass, which gets at one of the perceptions about class D.
Any thoughts on that?
Thanks,
