I keep yapping about ’stereo pairs’ of subs, front facing, no ports, locate adjacent to mains: giving/preserving bass directionality, by virtue of both the fundamentals and overtones of those fundamental notes.
Some of the best statement systems have front facing subs or woofer towers for the exact reason you mention (it works better). I will never sell my Infinity RS1B woofer towers...unless maybe for a set of Genesis woofer towers.
