Bi-amping RTi A3 speakers

[rampantandroid]

Hi all,

Thinking of taking on a chipamp project to match a pair of Polk RTi A3 speakers (bookshelf speakers) that have posts to be bi-amped. In your opinion is it worth bi-amping those speakers? Or should I just stick with a good two channel chipamp?

Thinking of doing a 4 channel chipamp with active xover built into the amp itself - does this seem like a wise idea?

Has anyone done this with this series of speaker before (meaning, can someone attest to what improvements they saw, and what XOver frequencies they landed on?)

Thanks!
RA
