Test tones and an SPL meter might help. Set your sub to kick in where your B&W's start to roll off. Even though you might have sound down to, say 35Hz, they might be down 10db at 35Hz starting at 50Hz. If this were the case, I'd set the sub X-over at 50Hz and set the gain to maintain the same SPL as far down as your sub will go.
Crossover frequency
I am trying to set my system up for maximum benefit. I recently purchased a pair of B&W signature 805 and am using a hsu vtf 2 sub. I can set my meridian processor for any crossover but am not sure of the best. I use 80 for HT per thx, but feel my speakers could go lower for stereo.
Thanks,
