I have a wonderful CS400i that I just really dig. However, I was curious about biamping the speaker. The manual mentions high and low frequency amplifiers, so this would indicate that the amp would need to have an active crossover. However, this kinda spits in the face of the fact that the speaker has a built in crossover. Before I go an hook this all up, do I need to crossover my amp, or just take the jumpers out and go to wiring? Thanks for your help, any and all!
