Product Overview & Specifications
The Q Acoustics Q SUB80 is a compact active powered subwoofer designed to bring well-controlled, deep low-frequency extension to smaller rooms and space-conscious audio systems. Built into a compact 13.9-liter infinite baffle cabinet, the Q SUB80 features an 8-inch (203 mm) driver powered by a quad-stage Class D amplifier delivering 200W continuous output (400W peak) with a clean 0.09% THD distortion rating.
Integrated Digital Signal Processing (DSP) optimizes performance dynamically by detecting input signal levels and automatically managing system gain. Dual-phase and delay controls allow fine-tuned signal alignment across various room boundaries, while a variable low-pass crossover (50 Hz – 250 Hz) ensures seamless integration with compact bookshelf speakers or satellite channels.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- 8-Inch Long-Throw Driver: 203 mm woofer mounted inside an ultra-compact, sealed infinite baffle enclosure for articulate and fast bass output.
- Smart DSP Engine: Integrated Digital Signal Processing continuously analyzes incoming signals to optimize gain structure and maintain distortion-free playback.
- Quad-Stage Power Amplifier: High-efficiency digital amplifier featuring four output stages for reduced thermal loss, low output impedance, and precise cone control.
- Phase & Delay Fine-Tuning: Dual-phase and signal delay controls provide accurate timing matching and flexible acoustic placement near walls or corners.
- Variable Low-Pass Crossover: Adjustable 50 Hz – 250 Hz low-pass filter for smooth frequency handover to partnering stereo or surround speakers.
