Description
WHY: At ASCENDO, we believe that powerful, deep, and distortion-free bass should be accessible to everyone. With THE15 SUB PASSIVE VENTED, we wanted to create a subwoofer that offers the same renowned ASCENDO quality at an affordable price, all while meeting the demands of our distributors and customers.
HOW: Our 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 our 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.
WHAT: 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.
