Definitive Technology Descend Series DN15 – 15″ Subwoofer

Monumentally Uncompromised Performance Definitive Technology’s most powerful subwoofer ever, the DN15 brings massive, uncompromising bass performance to your high-end system. Loaded with custom technologies such as 3XR Architecture, Intelligent Phase Control, Class H digital amplification, and an advanced 56-bit DSP, the DN15 creates extremely loud, low, clear bass that adds massive impact to your home theater. 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. 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 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 for pure, commanding performance down to 20Hz 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. 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 most impactfully accentuate explosions and other special audio effects. Team Player! Control and Customization 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 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. 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. Owner’s Manual Information Sheet
