No matter if it’s a stereo set-up or full-on surround-sound cinema system, the Q SUB120 can fill your listening room with that infra-bass Low Frequency Effect you can feel as well as hear. Big room with big speakers? No problem… 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.
