This isn’t your average subwoofer.
The HSU Research ULS-15 MK2 is a 15-inch, 65-pound beast built to move serious air and shake your walls with bass so deep and clean it feels like pressure more than sound.
If you’ve never heard true low-end extension below 20 Hz, this will be a revelation. Explosions hit with physical force. Kick drums sound alive. Movie soundtracks feel cinematic. Yet it’s still tight, musical, and accurate.
Specs:
– 15-inch front-firing driver
– Sealed cabinet, 600 W RMS (2000 W peak)
– Response down to 20 Hz
– RCA and XLR inputs
– About 65 lbs
In excellent condition, from a smoke-free home. Works perfectly.
New, this model sells for $999 direct from HSU.
Price: $400 firm
Condition: Excellent
Pickup: Local pickup only in Staten Island — too heavy to ship.
If you want real, room-shaking low end without sacrificing musical detail, this is the sub.
Bring a friend, and maybe a dolly.
