Smaller rooms with smaller speakers still deserve big, well-controlled bass for listening to music or watching movies. The Q SUB80 with its 8in driver is the ideal partner for M20 or M40 active speakers or 3000c and 5000 Cinema Packs in ones or twos. OVERVIEW Q SUB80 has exceptional bass power to cabinet size ratio. 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.
