Massive, uncompromised bass performance, from our most powerful subwoofer ever. Unique technologies add unprecedented clarity, power and seamless system integration. 

3XR™ Architecture

The DN15’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 DN15 to play as loud and low as a two similarly-sized 18” ported subwoofers. And because 3XR doesn’t use ports, DN15 also provides massive, crystal-clear bass with no port noise distortion.

Passive Radiators

As the core technology behind Descend’s 3XR Architecture, its passive bass radiators enable the DN15 to play as loud and low as two 18” ported subwoofers 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 then a ported sub from a smaller enclosure than a sealed sub.

Massive Impact

Powered by Class H digital amplification, and with an advanced 56-bit DSP that includes three custom EQ modes, DN15 plays exceptionally impactful bass down to 20Hz.

Custom Class H Digital Amplification

The DN15’s advanced 1500W peak Class H digital amplifier delivers continuous power to cleanly reproduce sustained bass below 20Hz. With real-time monitoring and adjustments to the sliding rail voltage, the DN15 delivers considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts.

Advanced 56-Bit DSP

The advanced 56-bit Digital Signal Processor (DSP) extends and improves the DN15’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 artefacts.

Built-in EQ Modes

With three built-in performance EQs modes, the DN15 can be optimised to your room and listening preferences, and adjusted to match whatever you’re listening to.

Team Player Control and Customisation

With breakthrough technologies such as Intelligent Phase Control™, easy settings management with its dedicated remote control, and advanced custom integration capabilities, the DN15 is easily optimised to the specifics of your system.

Intelligent Phase Control™

Intelligent Phase Control™ provides a full 360 degrees of customisable phase adjustment, always centred around the settings of the low-pass filter. This provides the ability to tune the subwoofer for minimal group delay between speakers and a flawless blending experience between your speakers and the subwoofer. 

Remote Control with On-sub LED Display

Easily adjust the DN15’s volume level, phase, and EQ with its slim remote control. There’s no need to constantly get up to manually change settings or wonder if you’ve gotten them right.

Multiple Subwoofers

While a single subwoofer can add bass and enhanced realism to any system, it may not provide consistent frequency response throughout the room. When two or more subwoofers are properly employed throughout the room, sound waves disperse more evenly, flattening the frequency response. The result is smoother bass throughout the room, helping to eliminate boomy locations or dead spots.

Custom Integration

With both 12V input and IR pass-through, you have the ability to pair the DN15 with most control systems and place the subwoofer wherever you want in the room and still experience full functionality.
