I was looking for my next diy project. I really need some towers for my fronts and I came across speakerbuilder.net and the D8 project. Anyone out here build em'? I have a few questions. 1. What kind of power handling/ sensitivity do they have? 2. I don't have seperates yet don't want fry my receiver 3. Can they be bi-wired/bi-amplified? 3a. Is this just a matter of making the low-pass and high pass part of the crossover separate, and using a bi-wire term cup? Any help or advice is greatly appreciated.
