The QB 12 is Q Acoustics' first subwoofer with a 12 "element.
The large and long-lasting element is commanded by a 220-watt Class D amplifier with extremely low distortion, which produces polar and dimensional bass reproduction. The subwoofer is great for supporting the Q Acoustics Concept Series for both movies and music.
The Q B12 works in a closed housing that is very rigid thanks to the cross-support structure so it does not color or resonate.
The subwoofer's enclosed "infite baffle" housing is cleverly reinforced to give maximum rigidity to its system, and as a result, minimal impact on those deep bass sounds. Mechanical Stability = sound enjoyment.
Reinforced MDS housing with 36mm thick front panel, recessed and hidden terminal panel. Adjustable spike legs with rubber covers. A range of elegant, simple finishes. The Q B12 is simple and easy to place and deploy. It is also refreshing to listen to.
