Sogood51...I am now set up with a crossover where I can alter the SW X/O frequency while music is playing by twisting a knob, and my ears and my spectrum analyser tells me what happens.
With a white noise test signal (flat 20-20KHz) I am able to vary the X/O frequency from 50 to almost 200 Hz with no audible or visible spectral change to the sound. This tells me that I have got the SW well matched to the mains. With music, I sometimes vary the X/O frequency.
With "heavy" sound, like organ, choral, or some orchestral, the six big cone drivers in the subs work better than the Maggies, and I crank it up to about 150.
My room resonates at about 60 hz. Always has with any speakers. Rives uses 70 Hz as his example on the web site. If you are lucky enough to have a larger room it will be lower.
