The Q Acoustics Q SUB120 is the flagship model in Q Acoustics' "Q SUB" series, released in 2025. It is a high-performance, active 12-inch subwoofer designed to provide deep, cinematic bass while maintaining the "musical" and controlled character the brand is known for.

It is significantly more powerful than the older QB12 model and is designed to anchor both high-end home cinema setups and 2-channel hi-fi systems.

Product description

The Q Acoustics Q SUB120 is the flagship of the company's new active subwoofer lineup. It is a powerful, 12-inch sealed subwoofer designed to handle both deep home cinema "infra-bass" and precise musical low-end.

Key Features & Technology

  • Sealed Cabinet Design: Unlike ported subwoofers that can sound "boomy," the Q SUB120 uses an infinite baffle (sealed) design. This results in tighter, faster, and more accurate bass, which is ideal for listeners who want their subwoofer to blend seamlessly with music.

  • Smart DSP (Digital Signal Processing): The onboard DSP automatically identifies the input signal (stereo vs. mono) and adjusts gain for optimal performance. It also handles phase inversion and fine delay adjustments to help the sub stay in perfect time with your main speakers.

  • Advanced Internal Bracing: The cabinet uses 18mm MDF with a double-thickness 36mm baffle. It features "Dart Bracing" to prevent the cabinet from "ballooning" under the high internal pressure created by the 12-inch driver.

  • Parallel Bridge-Tied Load (PBTL) Amp: The custom amplifier module uses four digital power stages in a parallel configuration. This improves efficiency, reduces heat, and provides better control over the driver's movement.
