Massive Performance

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.

Loud & Clear

Descend's unique 3XR Architecture provides triple the bass-producing radiating surface area of a traditional 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.

Precision Tuning

The DN15's advanced Class H digital amplifier delivers continuous power to cleanly reproduce sustained bass below 20Hz. The DN15 delivers considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts.

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.

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.

Custom Class H Digital Amplification for pure, commanding performance down to 20Hz The DN15's advanced 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.

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.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
