Definitive Technology DESCEND DN15 15" Subwoofer with Dual Bass Radiators

Mind-blowing bass--bigger and badder than you've ever heard--from the wildest subwoofer around! Our revolutionary tech unlocks a whole new level of jaw-dropping clarity, oomph, and system compatibility.

3XR™ Architecture
The DN15's 3XR Architecture provides 3x the surface area of a regular 15" ported sub, so you get the same volume and ultra-low bass as two 18" ported subs - without any port noise distortion!

Passive Radiators
DN15 rocks the house with its 3XR Architecture: twin 15" passive bass radiators give you the deep, low-end rumble of two 18" ported subs without the nasty distortion. Plus, you get the smooth sound of a sealed box, plus the party-starting loud and low of a ported one, all in a slim package.

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, authoritative performance, the DN15's 1500W Class H digital powerplant dishes out uninterrupted oomph even at lows below 20Hz. Continually monitored and dialed-in with a sliding rail voltage, the subwoofer serves up some serious brawn during intense bass waves, like a kick-drum boom or an explosive battle scene.

Advanced 56-Bit DSP
For distortion-free longevity and punch, the DN15's got you covered with an advanced 56-bit DSP. This nifty processor continuously tracks and manages the subwoofer system, meaning you can crank up the volume without worrying about pesky distortion or any unruly woofer damage.

Built-in EQ Modes
For the optimal auditory experience, the DN15 comes fully stocked with 3 performance EQ modes, allowing you to adjust to and get the most out of any listening environment!

• 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.

Control and Customization
Boasting impressive tech like Intelligent Phase Control™, simplified adjustments with an exclusive remote, and custom integration options, the DN15 is the perfect fit for personalizing your sound system.

Intelligent Phase Control™
For a seamless system synergy. Our Intelligent Phase Control™ gives you an entire 360°of customizable phasing, always focused on the low-pass filter's settings. That way you can tune your subwoofer for as few group delays between your speakers and a perfect integration of the sub and main speakers.

Remote Control with On-sub LED Display
Easily tweak the DN15’s volume, phase, and EQ with its handy little remote control--no more getting up and down, and no more guesswork!

Custom Integration Ready
For total customizability, you get 12V input and IR pass-through, so you can put the DN15 sub anywhere and still have full control - no matter your setup!
