The Ascendo The Sub 15 convinces in every single aspect, whether in high-profile home theater systems or the editors of renowned worldwide magazines. Awesome performance paired to excellent sound quality dressed in an amazingly compact enclosure – these are the mainstays of this successful and award-winning conception.
The custom-made 15-inch high-tech woofer is equipped with an extremely strong neodymium magnet. Although its cone is very tightly suspended, thus allowing an exceptional high acceleration and control, it shows up with a linear stroke of record-breaking 36mm.
Thus, this unique driver even moves significantly more air than much bigger standard 18″ subwoofers. Its bass impact and authority are really stunning. The closed and DSP controlled The Sub 15 with its 1500 watts of power impresses with its speed. Remarkable with which timing and resolution the subwoofer plays also the lowest lows right to the point. With these outstanding features it is ideally suited for all cinema sizes and modern 3D sound formats such as Dolby Atmos, Auro 3D or DTS:X, but as well perceptibly enhances high-quality stereo high-end systems right from the beginning.
