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.
