    EQ, and control features.

    3XR™ Architecture

    More Bass from
    the Same Space

    The DN15’s unique 3XR Architecture provides triple the bass-producing surface area of a traditional 15” ported subwoofer. This extra surface area moves more air, resulting in monumental 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 two ported 18” subwoofers

    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.

    Learn how it works

    Passive Radiators
    for louder, lower,
    cleaner bass

    As the core technology behind Descend’s 3XR Architecure, 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 than a ported sub from a smaller enclosure than a sealed sub.

    Massive Impact

    Absolutely Uncompromised

    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
    for pure, commanding
    performance down to

    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
    for distortion-free
    longevity and impact

    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 artifacts.

    Built-in EQ Modes
    for the right sound every time

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

    Flat Mode

    The DN15’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.

    Team Player

    Control and

    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 optimized to the specifics of your system.

    Intelligent Phase Control™
    for flawless system

    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.

    Learn how it works

    Remote Control with
    On-sub LED Display
    for adjustments on the fly

    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
    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.

    Custom Integration
    for complete

    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.
