I agree I love my M gear but this AC12 is a little hard to swallow cost wise plus lack of making it work in the real world. I don't know how many non speakerlink speakers out there have BNC comms but I bet the majority are S comms and most M owners I bet don't have extra M lead cables sitting around to swap out for all the S cables.
To make it worse for custom install wiring (inwall) I will need to solder at the back of my equipment rack ( instead of on a bench top).
I guess if this isn't fixed by a firmware change (it may not be cabable of that) than I will be asking some soldering questions in another thread.
