I have Yamaha HS8 monitors and previously bought an HS8S matching sub for them, which is great, but I couldn’t feel the sound in my body as much as I wanted with it. So I decided I need a bigger woofer :) And rightfully so, because this thing slams! I was really wondering if my neighbors would be bothered. But as soon as it arrived and I plugged it in, this is no longer a question - they will. Needless to say, I’m returning Yamaha back to Amazon and buying a thick acoustic pad from Thomann because I’m not sure the one that comes with KRK is enough for neighbors comfort (it’s just a 3mm neoprene like sticky pad).
This sub seriously brought the sound to the new level, whether it’s watching Andor, or playing Battlefield 6 on PS5 (I can feel those helicopters like there’re there, my wife even commented that now the sound if life-like), or just listening to familiar songs, they just sound like I’ve never experienced them before, even with another (smaller) sub.
I set the input sensitivity to Nominal (default is High), and it made the punch much tighter. I use 3 o-clock volume position on the sub and 12 o-clock on HS8, with crossover set to 80Hz and very happy with the result. This is a BIG BOY and it arrives in an enormous box, so be sure you have space for it. I had to place mine upright for it to fit.
