A bigger space demands bigger bass - and that’s exactly what the Q SUB100 provides. Its 10" driver and effortless performance make it the perfect low-frequency partner for Concept loudspeakers, as well as every other medium-sized passive speaker in QAs line-up. 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.
