Welcome to the Speakerbuilder.net discussion forum. While being polite and respectful is not common on the internet, please try not to flame people who don't deserve it. Otherwise, go nuts.
I built the Mk1 and modified the crossover to enable me to biwire without any problems. Took my speakers around to a friends house and he BiAmps a pair of Spendor S8's with Linn LK85 amps. I'm no expert but they sounded sweet to me...and him!
I've e-mailed you my version of Wayne's crossover for you to consider and/or get checked out. It only really involves removing a couple of the existing links. I'm away until the New Year but may get chance to view the forum back home.
