I would like to hear what my system would be like with my subwoofer filling in only the bottom portion of bass that my front speakers cannot manage. My fronts go down to 32 hz -3 dB anechoic. I am guessing if I got a crossover that had a range from 20 to 35 hz, I could use it to run my subwoofer off of my receivers front left and right main pre-outs. This would allow me to run the fronts LARGE and also SOURCE DIRECT and still have my subwoofer filling in the bottom end. Any suggestions? I am avoiding a speaker-wire crossover (passive) crossover because thats another option I will consider, but my fronts are Bi-wired and really, that wouldn't work too well running bi-wires through my subwoofer!
