45 Sub

Powerful support

The A 45 SUB is a powerful active subwoofer that we have equipped with our largest amplifier electronics including bass management and wireless remote control. This allows it to support your home theater set or stereo system with the deepest bass in an impressive way. Its 12-inch driver with ceramic tungsten cone is suspended in our patented triple folded wave surround. It provides extreme dynamic capabilities, being able to put away enormous cone excursions in movie mode without complaint. Of course, this subwoofer is also ideally suited to support a stereo hi-fi system, with accurate drawing of all bass structures. Due to its design principle - bass reflex with downfire passive diaphragm - the potent subwoofer has pleasingly compact dimensions without having to compromise on sound. The housing has a high-quality finish, lavishly lacquered and available in white satin and black high-gloss.

System and components

The subwoofer's bass reaches down to an enormously deep 18 Hertz. The subwoofer's extremely powerful 750-watt digital power amplifier is equipped with high- and low-level inputs. Thanks to the A 45 SUB's built-in DSP and its four pre-programmed sound profiles, the subwoofer can be easily adapted to room acoustic conditions. The presets can be conveniently called up from the listening position via remote control. The volume level, phase adjustment and crossover frequency (50...200 Hz) as well as the practical automatic on/off function can also be controlled remotely. To connect another subwoofer, the active module is also equipped with a low-level output. On its four device feet with height adjustment and rubber coating, the 35 kilogram subwoofer stands securely on any surface. The acoustically neutral full-size fabric cover in black hides the direct view of the technology if necessary and holds elegantly by magnetic fastening on the solid baffle.

A strong team

With its 750 watt digital power amplifier, the A 45 SUB offers enormous power reserves for all applications - stereo and multi-channel. Thanks to the clever room adjustment, which can be set from the listening position via wireless remote control, the A 45 SUB is extremely flexible in handling. Whether you choose to place the subwoofer close to the wall or freely in your listening room is entirely up to you - the four presets make it possible. You can integrate the A 45 SUB perfectly into an existing home theater or with the jointly developed passive speakers of the A 45 series (A 45 - floorstanding speaker; A 45 BS - compact speaker; A 45 CS - center speaker; A 45 AR - Atmos speaker) put together a high-caliber home theater set that sets an absolute benchmark in the price range!
