The Q Acoustics Q Sub 120 is a high-performance 12-inch powered subwoofer designed to deliver deep, powerful and controlled bass for home theatre and high-fidelity music systems. With a 600W peak amplifier and a large 305mm (12-inch) bass driver, it produces room-shaking low frequencies while maintaining impressive control and precision.

Its infinite baffle enclosure and 44.1-litre effective volume allow the Q Sub 120 to extend down to 28Hz, while a maximum SPL of 114dB at 1m provides substantial output for medium to large listening spaces. The 300W continuous amplifier delivers consistent bass performance, while ultra-low 0.09% THD helps maintain clean and accurate low-frequency reproduction.

Advanced Digital Signal Processing (DSP) automatically identifies the input signal and adjusts system gain for optimized performance. Dual phase and delay controls provide greater flexibility when positioning the subwoofer, while the adjustable 40Hz–250Hz low-pass crossover enables seamless integration with a wide range of speakers.

With its sleek, minimalist design and powerful performance, the Q Acoustics Q Sub 120 is an excellent choice for upgrading a home theatre system with deeper cinematic impact, powerful bass and greater overall immersion.
