Definitive Technology Descend Series DN8 8" 500W Powered Subwoofer

    • The Definitive Technology Descend DN8 is a compact yet impressively capable powered subwoofer designed to deliver deep, impactful bass without taking up much floor space. Its standout feature is the 3XR™ architecture, which combines an 8″ long-throw active driver with two 8″ passive radiators, giving it about three times the radiating surface of a typical ported design, thus moving more air while remaining clean and avoiding port noise. Equipped with a Class-D amplifier that delivers 200 W RMS (500 W peak), the DN8 can reach down to ≈ 35 Hz (±3 dB), making it suitable for both music and home theater applications. Controls on the back include adjustable volume, low-pass crossover (60-120 Hz), phase switch (0°/180°), and power mode (auto or always on), which help in integrating the subwoofer seamlessly with different speaker systems and room acoustics. The DN8 also includes both LFE (mono RCA) input and speaker-level binding posts, offering flexible connectivity. With finishes in Glacier White or Midnight Black, and a form factor just over a foot wide, it’s built to fit in many setups without being obtrusive. Audiolab+3

Features:

  • The Definitive Technology Descend DN8 is an advanced, compact subwoofer designed in California for both music and home theater.
  • It is powered by a 500W peak Class D amplifier and an 8” driver that’s pressure-coupled with two 8” Ultra Low Bass Radiators. It delivers powerful bass with amazing speed, musicality, and control.
  • The DN8 is outfitted with dual 8” Bass Radiators that are pressure-coupled to the 8” driver.
  • The DN8 is the perfect complement to any home theater system. You can easily connect via LFE or stereo line level RCA inputs (cables not included).

3XR™ ARCHITECTURE MORE BASS FROM THE SAME SPACE

Descend’s unique 3XR Architecture provides triple the bass-producing 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.

PASSIVE RADIATORS FOR LOUDER, LOWER, CLEANER BASS

As the core technology behind Descend’s 3XR Architecture, its passive bass radiators enable the DN8 to play as loud and low as a 10” ported sub 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.

3XR ARCHITECTURE™ FOR AS MUCH BASS AS A PORTED 10” SUBWOOFER

The DN8 is equipped with a 500-watt peak custom Class D digital amplifier, designed to get the most out of the DN8’s 3XR Architecture. This custom amplification provides the Descend DN8 enough power and efficiency to play as low as 35Hz from a one-foot wide box.

CUSTOM CLASS D DIGITAL AMPLIFICATION FOR IMMEDIATE IMPACT

Because the DN8 Class D amplifier is so efficient, little power is wasted as heat, and its entire output is dedicated to providing significantly smoother bass and greater impact. This allows the DN8 subwoofer to blend naturally into any audio system while producing greater volume and impact than competitive designs.

CONTROL & CUSTOMIZATION PLAYS WELL WITH OTHERS

You can customize the DN8 to the needs of your application, system, and space. The DN8 features built-in controls for variable volume, low pass filter, and phase (0/180°) for optimum bass levels, and the ability to customize it to the specific needs of your system.

BACK PANEL CONTROLS

Manually adjust DN8’s variable volume, low-pass filter, and phase so it always sounds perfect within your system.

VARIABLE VOLUME
Adjust the volume level of your subwoofer to ensure perfectly proportioned bass for your audio system and your room.

LOW-PASS FILTER
Keep the bass clean by activating the DN8’s Low Pass Filter. The Pass Filter ensures that only the frequencies intended to be reproduced by the DN8 get through to the woofer. 100% of the DN8’s prodigious power goes to reproducing bass, and 100% of your amplifier’s power goes to vocals, instruments, and high frequencies. It doesn’t get cleaner than that.

PHASE
Adjusting the DN8’s phase control ensures subwoofer timing is tightly synced with the rest of the speakers, presenting pinpoint-accurate audio for movies and music.

ONE, TWO, OR FOUR SUBS 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.
