yes, yes, I was thinking along those lines last night after I posted it, and wondering if effects of hi pass, (not just steep acoustic roll off of driver), in the amp, relieving unwanted signal getting to the drivers might be a good thing.  Building band-pass filters, into the amp actually. 

I thought at least that channel was done.
Damn Cat!
Ok, digital experiments, then call Dave Slagle, get good iron & filter parts if it helps. 

Obviously when in amp filtration is THE filtration but…

1)    You do not know if it is necessary

2)    You do not know what is necessary (cut off and slop)

3)    If it is high order then you do not know if the topology of your amp would candle it

4)    You do not know if you need to use RL filtration.

The last one is the tricky one. The series capacitance is bad but if you channel does just LF, let say below a few hundred Hertz then, the negative contribution of series capacitance is kind of questionable…
