3XR™ Architecture

More Bass fromthe 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, cleanperformance down to25Hz

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-freelongevity

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.

Flat Mode

The DN12’s default setting out of the box, Flat Mode provides the most balanced performance, as determined by our acoustic experts, providing the perfect harmony between low end extension and full spectrum maximum output.

Deep Mode

Deep Mode provides additional low-end output but sacrifices some maximum SPL to do so. This makes Deep Mode excellent for music, where frequency range is so critical, so instruments like a pipe organ or an upright bass are fully and evenly reproduced.

Loud Mode

The opposite of Deep Mode, Loud Mode sacrifices some low-end output while gaining output in all other frequencies. Loud Mode is excellent for home theater, to best accentuate explosions and other special audio effects.

Control andCustomization

With breakthrough technologies such as Intelligent Phase Control™, easy settings management with its dedicated remote control, and advanced custom integration capabilities, the DN12 is easily optimized to the specifics of your system.

Intelligent Phase Control™ for flawless system blending

Intelligent Phase Control™ provides a full 360 degrees of customizable phase adjustment, always centered 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.

Intelligent Phase Control is available in the Descend DN12 and DN15 subwoofers.

Remote Control withOn-sub LED Display for adjustments on the fly

Easily adjust the DN12’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 for smoother bass throughout the room

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.

One subwoofer for increased bass performance

Two subwoofers for smooth bass impact

Four subwoofers for thunderous, smooth bass impact

Custom IntegrationReady for completecontrollability

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