I have the Rythmik FV15 and I'm now ready to add a companion sub. So of course the obvious pairing would be a second FV15...only problem being that Rythmik discontinued the FV15. I would guess that the FV15-HP would be the next best choice, but at $1200+ for each sub, I'm not really looking for the "next best". I know it is ideal, and some would argue imperative, to use identical subs in a multi-subwoofer setup. I'm wondering if there would be that much conflict between the FV15 and FV15-HP to cause noticeable acoustic problems.
Any advice?
