Unmatched Bass Depth and Power
The Q Acoustics Q SUB120 is a premium 12-inch (305mm) active subwoofer, engineered to deliver deep, thunderous bass with exceptional clarity and control. Designed for home theaters and high-fidelity audio systems, its sealed infinite baffle enclosure ensures precise, distortion-free low-frequency performance. Whether you’re feeling the rumble of an action movie or the resonance of a live concert, the Q SUB120 provides an immersive, room-filling bass experience that brings your audio to life.

Cutting-Edge DSP for Seamless Integration
At the heart of the Q SUB120 is advanced Digital Signal Processing (DSP), allowing for precise sound customization. The adjustable low-pass crossover (40Hz - 250Hz) ensures a perfect match with your main speakers, while intelligent source detection automatically optimizes gain levels for stereo or mono input signals. With low distortion (<0.1%) and an optimized response curve, this subwoofer delivers smooth, natural bass that seamlessly integrates into any audio setup.

Massive Power, Premium Construction
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. Available in satin black or satin white finishes, it complements any décor while offering auto power standby modes, adjustable spike feet for stability, and a sleek, modern design. Perfect for audiophiles and home theater enthusiasts, the Q SUB120 is the ultimate subwoofer for those who demand powerful, high-fidelity bass.
