[quote name='Paul S' post='364641' date='Dec 28 2008, 10:13 AM']My daily idiot question - can someone please explain what this 'biamp' thing is, please? In words of one syllable or less, and from the beginning.

Bi-Amping refers to using different amplifiers (or different channels of the same amp) for the low and high frequencies in the same speaker. Usually, the mid and tweeter are driven by one amp, and the woofer is driven by more powerful amp.
If a speaker is capable of bi-amping, then the plate on the back of the speaker will have 4 binding posts: 2 + terminals and 2 - terminals. Both + terminals and both - will have a piece of metal connecting them together. To bi-amp the speaker, remove the metal piece. Then, use the top 2 terminals for the high frequency amp, and the bottom two terminals for the bass amp.
