My speaker setup is REL Q150E subwoofer with Mission M72 cinema speakers package. I am using the single subwoofer cable from my amp to subwoofer, and all speakers set to "small" with crossover frequence 80 Hz. However, REL recommends that in addition to the the single LFE, we should also connect the main speakers (FL and FR) to the neutrik/speakon connector on the sub, and set the mains as large, so any LFE on the mains channels will go through the sub. Can someone tell me what's the point in that arrangement? Surely, if I set my mains as "small" then the LFE which was originally intended for that would be dvered to the sub anyway through the single subwoofer cable without needing the extra neutrk/speakon connections. Thanks.
