Definitive Technology DN15

Definitive Technology DN15 Ultra-Performance, 1500W 15″ Subwoofer with Dual 15″ Bass Radiators

Definitive Technology’s most powerful subwoofer ever 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.

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.

Reference-level Performance

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 powerful, clean performance down to 20Hz

The Definitive Technology 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

The advanced 56-bit Digital Signal Processor (DSP) extends and improves the Definitive Technology 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 Definitive Technology DN15 can be optimized to your room and listening preferences, and adjusted to match whatever you’re listening to.

Flat Mode

The Definitive Technology 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.

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 Definitive Technology 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.

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

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

Easily adjust the Definitive Technology 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 Ready for complete controllability

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.
