Q Acoustics Q B12 Subwoofer

The Q B12, a powerful subwoofer, is the latest addition to the Q Acoustics family. It's designed to seamlessly integrate with and enhance the award-winning Q Acoustics' 3000i and Concept 5.1 speaker ranges, offering expanded options for home cinema setups. Available in black or white, with high gloss or vinyl finishes, it complements both new and existing home cinema environments.

Uncompromising Power and Precision

As the largest and most powerful subwoofer in the Q Acoustics lineup, the Q B12 sets new standards. Its amplifier incorporates proprietary PurePath Ultra-HD technology, ensuring minimal distortion for a tight and forceful sound.

Exceptional Driver and Amplifier

Equipped with a long-throw 12-inch driver featuring high sensitivity and outstanding dynamics, the Q B12 is driven by a low-distortion 220W Texas Instruments TPA3255 Class D amplifier. This combination results in an extraordinary audio experience. The subwoofer's internal 'dart brace' design, housed within a reinforced MDF cabinet with a 36mm baffle, adds mechanical stability to the driver, reducing resonance and vibrations for a more precise bass response.

Punchy and Powerful Cinema Sound

The Q B12 Subwoofer is expertly engineered to deliver cinematic highs and floor-shaking bass, all in an impressively sized subwoofer. Despite its magnitude, it maintains precision, detail, and dynamism. The incorporation of internal 'Dart bracing' for added cabinet rigidity and a reinforced MDF cabinet with a 36mm thick baffle work in harmony to suppress cabinet resonance, ensuring an accurate and immersive cinematic experience.

Seamless Integration

Designed to seamlessly integrate within Q Acoustics' renowned home cinema packages, including the Q Concept 5.1, Q 3050i 5.1, and the Q 3010i 5.1, available in various finishes. The Q B12 enhances the sonic capabilities of these setups, creating an even more impressive 'Plus-Size' cinema experience. It's also an ideal addition for those looking to elevate the low-end response in their existing home audio setup.

Effortless Setup

The Q B12 ensures a discreet setup with its recessed and concealed rear terminal panel, neatly routing all plugs and cables through the base of the subwoofer. Custom-designed adjustable spiked feet provide stability on carpeted floors, while reinforced rubber caps are included for use on wooden floors, ensuring optimal support for your subwoofer.
