Product Description

Features & Specifications



Definitive Technology DNSUB8 8″ Subwoofer – Black

DNSUB8 has unique 3XR Architecture™ means it performs louder and clearer than other 8” subwoofers.

  • Fits Anywhere: The DNSUB8 is just over one foot wide.
  • Loud & Clear: Unique 3XR Architecture.
  • More Bass: Like a 10” subwoofer in an 8” sub cabinet.

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 DNSUB8 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. What you get is the best of both worlds: louder, clearer bass than a ported sub from a smaller enclosure than a sealed sub. 3XR Architecture™ for as much bass as a ported 10” subwoofer.

Maximum Impact

The DNSUB8 is equipped with a 500-watt peak custom Class D digital amplifier, designed to get the most out of the DNSUB8’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 DNSUB8 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 DNSUB8 subwoofer to blend naturally into any audio system while producing greater volume and impact than competitive designs.

Plays Well With Others

You can customize the DNSUB8 to the needs of your application, system and space. The DNSUB8 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 for Optimized Bass Levels

Manually adjust DNSUB8’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.

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.
