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