Q Acoustics Q SUB80 / 8'' Subwoofer

Q SUB80 has exceptional bass power to cabinet size ratio.
This subwoofer is more powerful than the previous QB 12 model.
Digital Signal Processing (DSP) allows easy system and room integration with optimise settings for class-leading, distortion-free performance.
Clever, dual phase and delay controls allow the fine-tuning of the signal alignments for flexible room placement.
DSP identifies the input signal and automatically adjusts system gain, enhancing performance regardless of the connected source.
A low pass filter with frequency adjustment ensures seamlessly integration with any partnering speaker system.

A custom-designed amplifier module features four digital power amplifier stages that improves efficiency by dissipating less heat, enhances speaker control, and reduces output impedance.

Whether as part of a Q Acoustics home cinema set-up, adding effortless bass extension to your existing 7.2, 5.1 or 2.1 system or intensifying the low end on your powered/active speakers, these new subwoofer models will deliver the dramatic to movies and music.

Whatever the size of your home cinema room or the power of your system, Q Acoustics has the right-sized model to fill your space with powerful, impactful but nuanced and controlled bass. The new subwoofer family consists of the 8-inch Q SUB80, the 10-inch Q SUB100 and a 12-inch model, Q SUB120.

Placement in a room can impact sound arrival timing, while phase alignment issues can arise even with adjacent subwoofer placement, affecting system frequency response. The Q SUB range uses Digital Signal Processing (DSP), alongside fine delay adjustments and phase inversion switch, to address these integration challenges. This technology enables users to optimise settings for a class-leading performance, ensuring seamless integration with other speakers without needing professional installation.

Subwoofers must accommodate a wide variety of sound input sources, including stereo preamp outputs or mono feeds from active speakers or home cinema systems. The Q SUB range uses a complex algorithm inside the DSP to identify the input signal type – stereo or mono and the level – and automatically adjusts system gain. This ensures optimal signal to noise levels and dynamic range, enhancing performance regardless of the connected source.
