Q Acoustics-Q Sub 120-12-inch subwoofer

The Q Acoustics Q SUB120 is a high-performance 12-inch powered subwoofer engineered to deliver deep, controlled bass for both stereo and home theater systems. It features a 305 mm (12-inch) bass unit housed in an infinite baffle (sealed box) enclosure, ensuring tight and focused low-frequency response. The subwoofer is powered by a custom-designed amplifier module that includes four digital power amplifier stages in a parallel bridge-tied load (PBTL) configuration, delivering up to 300W continuous and 600W peak power with a total harmonic distortion (THD) of less than 0.1% at rated power. Its frequency response spans from 28 Hz to 250 Hz, with a maximum sound pressure level of 114 dB at 1 meter, providing impactful bass that enhances music and movie experiences. The Q SUB120 incorporates Digital Signal Processing (DSP) for easy system and room integration, featuring adjustable low-pass crossover (40 Hz – 250 Hz), phase inversion, and delay controls to fine-tune performance. Its minimalist design is available in Satin Black or Satin White finishes, allowing it to blend seamlessly into various interior décors.
