Definitive Technology Descend DN12: Ultra-Performance 12-Inch Subwoofer

The Definitive Technology Descend DN12 is an ultra-performance subwoofer loaded with custom technologies, delivering extraordinary, reference-level bass that integrates flawlessly into any home theatre or music system. Engineered for clean, sustained low-end performance and designed to perform as powerfully as a larger ported subwoofer, the DN12 is the ideal solution for medium to large-sized listening rooms.

3XR Architecture for Massive, Clear Bass

The core innovation of the DN12 is the proprietary 3XR Architecture, which provides triple the bass-producing radiating surface area of a traditional ported subwoofer.

The system features one 12-inch Long-Throw Woofer paired with dual 12-inch Passive Radiators. This configuration moves significantly more air, resulting in massive low-end output and enabling the DN12 to play as loud and low as a larger 15-inch ported subwoofer. Crucially, because the 3XR Architecture does not utilise ports, it delivers crystal-clear sound with no port noise distortion. The passive radiators also ensure a smooth frequency response, similar to a sealed design, while providing the volume and depth typically associated with ported enclosures.

Advanced Custom Amplification and Control

The DN12 is powered by a custom Class H Digital Amplifier that provides continuous power to cleanly reproduce sustained bass down to 25 Hz ($\text{+/- 3 dB}$). The Class H design features real-time monitoring and adjustments to the sliding rail voltage, allowing the amplifier to deliver considerably higher power during short, transient peaks—such as on-screen explosions or bass drum kicks—ensuring powerful, clean performance.

Advanced control features allow for perfect system blending:

• Intelligent Phase Control™: Provides a full 360 degrees of customisable phase adjustment, centred around the low-pass filter settings. This capability allows users to tune the subwoofer for minimal group delay between speakers, achieving a flawless blend between the subwoofer and main speakers.

• Advanced 56-Bit DSP: A sophisticated Digital Signal Processor (DSP) tightly monitors and controls the woofer system to prevent distortion and damage at ultra-high volumes with minimal audible artifacts, extending and improving bass response.

• Custom Integration Ready: With 12V input and IR pass-through, the subwoofer can be paired with most external control systems for complete, versatile controllability.
