Bi-Amping KEF speakers

Michael Gilligan · 27th December 2011, 09:41 PM

As a new member; let me say how impressed I am with the depth and quality of discussion on his forum.

I think my question is reasonably novel, but forgive me if it has been adequately covered elsewhere.

We are soon to finish an extension to the house, and my beloved KEFkit 3 speakers will be coming out of hibernation.
See here ... KEFKIT 3 page 1

Whilst these are 3-way speakers, the [very simple] crossover lends itself to a 2-way split; conveniently separating the Bass unit from the Midrange & Tweeter.

My plan is to Bi-Amp, using two LM3886 Chip Amps per channel; each feeding one section of the modified crossover.

Should I do anything to modify the bandwith of the amplifiers?
or simply let them all feed full-spectrum into the crossover components?

I would be most grateful for any words of wisdom.

P.S.

For anyone interested ... Here is a schematic of that very simple crossover

To get the most out of these, i would encourage you to remove some of the passive XO parts and add a 1st order PLLXO in front of the chipamps and move the XO down to ~200-250 Hz.
