Sound perfection. The low sound of a contrabass, the dark resonating beats of a kettle drum, the dull rumble of the storm, and often a resultant thunderous shake – it is often the subwoofer, which brings the experience to life. To render the low frequencies powerfully, membranes, cabinet, and electronics and their interplay were developed specifically for the job.

A quadral subwoofer relieves the other speakers in the array, allowing them to then concentrate completely on the mid and high frequencies while the subwoofer drives that low end – with detailed precision, speed and depth.
