I touched on this earlier, but I have a pair of the same subwoofers. My son has an excellent ear for music and his hearing is better than mine. He talked me into increasing the gain on the subs tonight and it definitely helped add some fullness to songs that had sounded thin. The gain is set really low and even one click makes a difference. I don't like boomy bass. We left the crossover frequency really low.
The tweaking all started when I did an a/b comparison between my dac/streamer and my sacd player. The sacd player initially sounded better until I realized that my dac had somehow had the filter changed from fast to slow. The slow definitely has a warmer sound, but I wasn't looking for warmth. If your dac has filter settings, you might try changing those.
I've also been able to add warmth with certain copper cables.
Anyway, this is probably all stuff you know, but I thought I'd share my experience.
I've liked the B&W speakers that I've heard. The brightness that I mentioned was just from comments that I had read.
