The Definitive Technology Descend DN15 is a high-performance 15” powered subwoofer designed to deliver exceptional bass with precision and depth. Equipped with a powerful 500W RMS Class H amplifier (1500W peak), it produces deep, distortion-free sound at all volume levels. Its proprietary 3XR™ architecture, featuring dual 15” passive radiators, significantly increases radiating surface area, enabling bass output comparable to larger subwoofers while maintaining a sleek, space-saving design.
Built for versatility, the DN15 integrates seamlessly into any home audio system with multiple connection options, including line-level RCA inputs, LFE input for home theater receivers, and speaker-level binding posts. Its Intelligent Phase Control™ (adjustable from -135 to 180 degrees) enhances bass integration, eliminating placement guesswork. The sub also includes a variable low-pass crossover (40Hz to 150Hz) for precise frequency adjustment.
The DN15 offers three customizable EQ modes—Flat, Deep, and Loud—allowing users to tailor the bass response for movies, music, or balanced audio performance. The built-in 56-bit Digital Signal Processor (DSP) ensures clear, high-output bass while minimizing distortion. Convenient back-panel buttons and an included remote control make adjustments effortless.
With a premium black finish and an LED display for easy status reference, the Descend DN15 combines powerful performance with elegant design. Whether for immersive cinematic experiences or deep musical bass, this subwoofer delivers dynamic, high-impact sound with unmatched precision.
