Overview

At ASCENDO, they believe that powerful, deep, and distortion-free bass should be accessible to everyone. With THE15 Sub Passive Vented, they wanted to create a subwoofer that offers the same renowned ASCENDO quality at an affordable price, all while meeting the demands of the most discerning customers.

Ascendo Audio's design philosophy centers around the perfect balance of extension, punch, and accuracy. THE15 Sub Passive Vented delivers deep bass without compromising performance, with a meticulously selected tuning frequency of 27 Hz.

The vented enclosure enhances the lower frequency response, and Ascendo's exacting engineering guarantees top performance through a high-temperature voice coil, linear suspension, and robust magnetic motor system. The heavily braced enclosure effectively reduces undesirable resonances, delivering impressive internal and external sound clarity at a more affordable price point.

THE15 Sub Passive Vented is a 15-inch subwoofer made with precision engineering. It has a 4-inch voice coil for high long-term reliability, and is designed for amplifiers with 750 to 1500W power output at 4 ohms. The cast frame further enhances the design by eliminating resonance.

THE15 Sub Passive Vented provides the highest sound pressure level (SPL) paired with in-room extension down to 20 Hz, whether you’re installing it in a home theater or commercial space. The shallow design allows for flexible placement with no compromises to sound quality. Trust in the verified performance metrics from third-party testing and enjoy a powerful bass experience tailored for optimal cinema sound.

*For optimal performance, use with ASCENDO subwoofer amplifiers.
