Has anyone ever done this with their Carvin LS1503 cab ? Now that I use the BX1500, which is bi-amp capable, I'm kinda curious as to how it would sound as compared to full range? Also, not real sure how to wire the speakons. The manual gives a wiring description for bi amping, but it sounds like they are describing how to wire it up for one speakon only. I clearly need to use two speakons with the BX1500, so I'm kinda puzzled about this. Any help or comments ?
