I've had this question for a long time, and I've never been able to get a good answer. Is there bass management hardware and / or are there AV Controllers out there that allow you to set subwoofer crossovers where you want them for EACH SPEAKER? In other words, say I've got a nice pair of mains that can truly perform down to 40 hz or so. Then say my center needs help below 100 hz. My rears? Somewhere between 60-80 hz, they lose it. Does anyone else think that setting my speakers to "Large" or "Small" is not enough? Why should I send all 80hz and below to the sub when I've got truly "Large" speakers? But on the other hand, why should I live without that last octave just because I want almost all of my stereo music to come from my mains? Although my center is set to "Small", it is still dealing with a small amount of 80-100 hz material that it isn't best at. I think I've said enough? What do I need (a life?) ?
