Definitive Technology Descend DN12 Subwoofer
Description
Descend Series DN12 12” Subwoofer
Reference-Level Performance
Ultra-Performance, 1500W 12" Subwoofer with Dual 12" Bass Radiators
Loaded with custom technologies such as 3XR™ Architecture and Intelligent Phase Control™, the DN12 delivers extraordinary bass into any system.
More Bass from the Same Space
The DN12’s unique 3XR Architecture provides triple the bass-producing surface area of a traditional 12” ported subwoofer. This extra surface area moves more air, resulting in massive low end. And because 3XR doesn’t use ports, it also provides crystal-clear sound with no port noise distortion.
3XR™ Architecture for as much bass as a ported 15” subwoofer
The DN12’s 3XR Architecture provides triple the bass-producing radiating surface area of a traditional 15” ported subwoofer. This extra surface area moves more air, enabling the DN12 to play as loud and low as a two similarly-sized 18” ported subwoofers. And because 3XR doesn’t use ports, DN12 also provides crystal-clear bass with no port noise distortion.
Passive Radiators for louder, lower, cleaner bass
As the core technology behind Descend’s 3XR Architecure, its passive bass radiators enable the DN12 to play as loud and low as a 15” ported sub without unwanted port noise distortion. Passive radiators also deliver a smooth frequency response like a sealed sub, but with the port-like ability to play louder and lower in a smaller enclosure.
What you get is the best of both worlds: louder, clearer bass than a ported sub from a smaller enclosure than a sealed sub.
Pure Impact Reference-level Performance
Powered by Class H digital amplification, and with an advanced 56-bit DSP that includes three custom EQ modes, DN12 plays exceptionally impactful bass down to 25Hz.
Custom Class H Digital Amplification for powerful, clean performance down to 25Hz
The DN12’s advanced 1500W peak Class H digital amplifier delivers continuous power to cleanly reproduce sustained bass below 25Hz. With real-time monitoring and adjustments to the sliding rail voltage, the DN12 delivers considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts.
Advanced 56-Bit DSP for distortion-free longevity
The advanced 56-bit Digital Signal Processor (DSP) extends and improves the DN12’s bass response. The DSP tightly monitors and controls the woofer system to prevent distortion and woofer damage at ultra-high volumes with a minimum of audible artifacts.
