I am running DEF TECH bp8's and a CLR 2002 up front and a set of bp2x's for the sides. I have the whole system set on full range. My fronts are all rated in 22-28 hz range and my rears are 45 hz. Should I turn off my subs crossover and just let the full LFE channel come in, I assume the DD and DTS standard is 80hz, is that right? Or should I set the subs crossover to approx 50 hz, about 5 hz above my bpx2's limits.
