The Q Acoustics Q SUB120 is a powerful active subwoofer designed to deliver chest-thumping low-frequency extension and infra-bass impacts for both high-end stereo setups and immersive home cinema systems. Housed in a sealed, infinite baffle cabinet with a 44.1-liter effective volume, the Q SUB120 pairs a custom 12-inch (305 mm) long-throw driver with a high-efficiency Class D amplifier capable of delivering 300W continuous output and up to 600W peak power with ultra-low distortion (0.09% THD).
Integrated Digital Signal Processing (DSP) optimizes performance across all listening levels, automatically sensing input signals to adjust system gain and prevent overdrive. With advanced dual-phase and delay controls alongside a fully adjustable low-pass filter, the Q SUB120 allows for seamless phase alignment and acoustic integration with partnering main loudspeakers regardless of room placement.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Custom 12-Inch Bass Driver: Long-throw 305 mm woofer mounted in a sealed infinite baffle cabinet for fast, tight, and articulate low-frequency reproduction.
