The Q Acoustics Q SUB100 is an active powered subwoofer engineered to deliver tight, impactful bass for medium-to-large listening spaces. Designed as a low-frequency match for Q Acoustics' Concept series and other passive bookshelf or floorstanding loudspeakers, the Q SUB100 pairs a 10-inch (254 mm) driver with a high-efficiency Class D amplifier in a compact 23.5-liter infinite baffle cabinet, outputting 250W RMS (500W peak) with ultra-low 0.09% THD.

Equipped with integrated Digital Signal Processing (DSP), the subwoofer automatically analyzes input signal levels to regulate system gain and maintain clean, distortion-free output. Advanced dual-phase and delay controls enable signal alignment across varied room placements, while a variable low-pass crossover ensures acoustic integration with partnering main speakers.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• 10-Inch Long-Throw Driver: 254 mm woofer housed within a sealed, infinite baffle cabinet for fast, articulate, and controlled bass extension.
• High-Efficiency DSP Engine: Integrated Digital Signal Processing optimizes gain response dynamically to preserve headroom and prevent signal clipping.
• Quad-Stage Power Amplifier: Custom amplifier module featuring four digital power stages for efficient heat dissipation, low output impedance, and precise driver control.
• Phase & Delay Optimization: Fine-tune timing alignment with dual-phase and signal delay controls to suit varied corner, wall, or open-room placements.
• Adjustable Low-Pass Crossover: Continuously variable low-pass filter (40 Hz – 250 Hz) enables seamless handover between subwoofer and stereo/surround channels.
