Cutting-Edge DSP for Seamless Integration
At the heart of the Q SUB120 is advanced Digital Signal Processing (DSP), allowing for precise sound customization.

With an impressive 300W continuous (600W peak) digital amplifier, the Q SUB120 offers deep, authoritative bass that maintains accuracy even at high volumes. Constructed from heavy-duty 18mm MDF with a reinforced 36mm baffle, the cabinet minimizes resonance for clean, tight bass reproduction.

Ava ★★★★★ Oct 22, 2026

That low-end rumble during action movies completely transformed my living room setup, and the tight control means it never sounds boomy even at higher volumes. The 12-inch driver digs deep into those low frequencies with a precision I haven't heard from other subs in this price range.

Jacob P. ★★★★★ Oct 21, 2026

I was a bit worried the 12-inch driver would overpower my room, but the bass sounds tight and controlled even at moderate volumes. The deep, thunderous low end brings movies to life without any muddiness.

Zoe O. ★★★★★ Oct 20, 2026

The 12-inch driver really earns its keep in my living room—even at moderate volume, movie explosions have a physical weight that my old setup just couldn't manage. Took a bit of fiddling with the crossover to blend it with my mains, but once dialed in, it's exactly the depth I was after.
