Critical subwoofer tip


I assume that everyone already knows the importance of phase matching a sub to the main speakers but it’s a little more complicated than simple 90 degrees or 180. The B&W sub that I have has four choices. In every case there has been a definite correct position that can be non standard. My current setup shined at 270 degrees vs the std positions. It’s completely obvious and the other choices would not have been satisfying. 
From my lengthy experience I would want a subwoofer with several phase choices. I personally don’t see how one could seamlessly integrate the mains and the sub without this flexibility. No one asked but i thought this info might be useful to anyone purchasing a subwoofer. YMMV

i certainly don’t know the technical issues involved in matching a single pair of loudspeakers to one subwoofer. I do know this though. If you can adjust the phase setting on your sub there will be a best choice. That’s my experience. 
I have an advantage in that b&w’s simple set up software allows you to perform all parameters from your listening position. via laptop you can set phase, crossover and gain very quickly by ear. once dialed in it sounds like the main speakers have great bass as you truly can’t locate the sub’s position. without the laptop set up i’ve had as much trouble as everyone else.
