I was thinking of an 802/511 combo for the HF. despite some "alweako" cracks, to me a paper cone and alnico magnet combo sounds awesome. does anyone have alternative suggestions for horns/drivers?

On the crossover, I thought bi-amping necessarily meant an active x-over before the amps. Is this not actually true? As you can tell, I know little audio theory. the dyna monos put out around 35-40 watts the hf amp will be 2-3 watts.

thanks again, EZ
