Definitive Technology Descend DN15BK Ultra-Performance 15″ Subwoofer

Descend DN15 Ultra-Performance 15-inch Subwoofer

The Descend DN15 Ultra-Performance Subwoofer is engineered to deliver extraordinary low-frequency impact with exceptional clarity and control. Designed as the most powerful subwoofer in the Descend lineup, the DN15 combines innovative acoustic engineering with high-output digital amplification to produce deep, authoritative bass without compromise. Its advanced 3XR architecture dramatically increases bass-producing surface area, allowing the system to move more air than traditional ported designs while maintaining clean, distortion-free output.

At the core of the DN15 is a 15-inch long-throw woofer paired with dual 15-inch passive radiators in a 3XR configuration. This design provides the equivalent air movement of much larger subwoofer systems, enabling thunderous bass performance that rivals dual 18-inch ported subwoofers. Because the 3XR system eliminates ports, the DN15 avoids port noise and turbulence, delivering tight, accurate, and articulate low-end reproduction even at high output levels.

Powering this performance is an advanced Class H digital amplifier that delivers sustained output for extended low-frequency passages while providing additional headroom for dynamic peaks such as cinematic explosions or percussive impacts. The DN15 is capable of cleanly reproducing frequencies below 20 Hz, making it ideal for both high-end home theater and demanding music playback.

User control and system integration are enhanced through rear-panel controls and an included infrared remote. Adjustable crossover, phase control, volume settings, and a disappearing front LED display allow precise tuning to match any listening environment. Finished in a refined cabinet with permanently installed feet and robust internal components, the Descend DN15 delivers monumental bass performance with precision, reliability, and long-term durability.
