I'm doing a surround sound installation in quad. Unfortunately, I don't have access to, or funds to acquire, 4 of the same speakers, so I'll be using 2 separate home stereo systems. One of these systems is a 2.1 system, so I was thinking I could sum the bass of all 4 channels into the sub (which has a separate input, independent of its satellite speakers).
My question is: how best to apply filters to send the appropriate sub signal to the sub and the rest out the other 4 channels. I've been messing around with onepole~ to supply the bass filter, and then subtracting its output from the original signal to supply the other 4. But I was wondering if this would be appropriate given the sample latency that is introduced into the system via the filter.
Does anyone have experience with this or something similar? Is there a better solution for bass management in such a set up? Will the latency introduced by onepole~ be noticeable (i.e. negatively effect the 'highpass' signal)?
Of course, time is a little precious, so I'd be grateful for any input.
