DaveF Posted January 14, 2022 Share Posted January 14, 2022 Regarding Heresy IV: When I remove the binding post bridge and connect a stereo amp to the lower two posts, I get sound from the woofer. connecting the amp to the upper posts gives sound from the mid range and tweeter. Does this imply that the internal/passive crossover is being bypassed for the lower pair? I am testing an active crossover (Ashly RX-1001) for horizontal biamping. The active crossover frequency is set at ~850 Hz. The high/mid output for each channel feeds a class A amp, which is connected to the upper pair of binding posts. The low outputs feed a class D amp, which is connected to the lower pair. I'm managing the gain difference with the Ashly's controls. In this case, is the signal from the class D amp going directly to the woofer and the signal from the class A amp going to the internal/passive crossover and then to the mid range and tweeter? I've seen suggestions that proper bi or tri amping requires bypassing the internal crossover, but I really don't want to mess around inside the speaker cabinet. This project is driven by curiosity, not necessarily the pursuit of better sound. It's a hobby... I do stop messing around and listen to music most of the time. But right now I'm trying to understand what's going on. 1 Quote Link to comment Share on other sites More sharing options...
