Hi everyone,

Here's one that probably gets asked alot, but I didn't see it on
google.

Can you biamp four post speakers using the "A" & "B" outlets on an
ordinary amp or receiver, then turning on the switches for both? Or
will the receiver simply put as much power as it has available into
the "A" (or "B")?

Does the power have to have special bi-amping capability, or do there
have to be two?

TIA

To bi-amp you need 2 amps and an electronic crossover. While it is
considered a more effective use of power, the problem IMO is that you're
re-engineering a set of speakers that (hopefully) somebody spent a lot of
time on getting it right. There's no reason to expect that a properly
designed passive xover won't work as well or better in splitting the
frequencies and sending them to their proper drivers.

If you have a powered subwoofer, then you have biamplification.

What you described is bi-wiring which has no proven advantage at all.
