Well, just to be contrary I'm gonna give it a go anyway. Worst case scenario is it sounds pants and I'll buy a high pass crossover. I wish I'd got a 4 channel amp with variable crossover points now, instead of just fixed 80Hz points. The bass amp has a crossover which varies between 20 and 250Hz, but it's never really seemed that impressive...

I'll let you know if I get any joy with this.

Cheers.

Andrew
