I have a set of Grund Audio dual 15" with horn and internal crossover that I want to re-wire to biamp with my external crossover. Can I just run new wires from the speakers straight to jacks or do I need any signal modification? Also should I wire the 15's parallel or series? The whole system will be run stereo 3way with a separate set of 18" cabs.

Does it make any difference on sound at all if a studio monitor is bi-amped or single amp meaning only one speaker has the amp and uses a crossover to divide the tweeter and woofer. I have heard the M-Audio AV-30 and it uses single amp and I think the sound was a lot more clear and better than my Roland DS-30A bi-amped monitor. Does bi-amp suppose to be better then single amp?

Has anyone test drove these yet? I'm looking to upgrade soon and a friend of mine just purchased a set from GC here in Northern Va about 3 weeks ago. The reason I have'nt bothered him on the performance thing yet is because he's in the middle of renovating his studio (as we speak) and he lives too far for me to get a chance to check them out.
