I use stereo subs in my system. I do not use my AVR's sub out; instead, I take the L/R line outputs into an external crossover to split the sub (LF) and mains (HF). I crossover around 50 Hz, a number that will vary with speakers and such. This also implies the main speakers and sub are run off their own power amplifiers, of course.
Finally I see someone who actually implemented this kind of setup. I like the idea of having a small satellite speakers (tweeter+ 4" midbass) and a subwoofer dedicated for that channel. It's basically making it a full range speaker 20Hz - 28kHz without the large imposing speaker. This would mean 5 or 7 Rythmik DS1200s plus two existing F25 CI as the true sub for LFE. Do you think it is going to cause problem like "cancellation issues"?
Actually, my main L/R speakers are Magnepan MG-IIIa's, a bit larger than your average little satellite. I have had several small satellite systems over the years and have just never liked them. They rolled off too high and I just never had a seamless transition to the sub. I am also on the low end of the localization frequency range, compounding the problem.
Most of the LF content is routed to the LFE channel in movies. I would think having all "large" speakers would be a significant challenge to dial in. Yes, all sorts of wave summing and subtracting.
I use a fairly cheap pro crossover (dbx 223s). Seems to work for me.
