Description

Urgewalt with sensitivity

It becomes clear at first glance what the new Q subwoofers were designed for. The massive aluminum die-cast baskets with diamond cut and the powerful 3-way ferrite magnet systems already visually signal that these subwoofers are serious. The extremely hard, hand-made diaphragms and oversized voice coils with enormous winding widths are predestined to set tremendous amounts of air into motion at low speed.

But with sheer force alone, it’s not enough – a lot of elaborate details of the design and the cleverly combined materials at the same time ensure extremely precise and dynamic bass reproduction that will satisfy even the most demanding music lovers.

Thus, the Q subwoofers form the perfect symbiosis of maximum sound pressure and unique sound quality in a new dimension.
