From the most subtle to the most intense shades, the QB 12 is Q's first subwoofer featuring a 12-inch driver. The long-excursion driver is powered by a 220 Watt ultra-low-distortion Class D amplifier for tight and powerful bass response and has a 50 mm voice coil for minimal thermal compression.

By combining the QB 12 with Q Acoustics' ‘Concept’ technology and the 3000i series of stereo and center speakers, it impressively delivers the big action moments of Hollywood, reproducing the deep and subtle aspects of bass.
