The system has to go on the longest wall as there's a fireplace on one end and a hallway opening on the other and more openings behind where we sit. This all plays into the exception category of, this is the wall you must use and this is where you must sit as the wife's not going let me block up the fireplace with an entertainment system.
The good news, at last REW measurement, the subwoofer null was in the 85Hz - 90Hz range and I was informed this is an inconsequential area of the subwoofer's sound spectrum. as there's little content to lose in the upper third of the LFE channel. All the rest of the speakers are crossed over to the sub at 60Hz, so nothing will be lost below the crossover point.
Happy, happy, hap-pi.
