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.

What you get is the best of both worlds: louder, clearer bass than a ported sub from a smaller enclosure than a sealed sub.

Powerful Amplification
Maximum Impact

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 for optimized bass levels

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 Low 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.


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.

Descend Series Subwoofers - Things Are About to Get Real

Whether movies, music or games are your thing, things are about to get real.

Engineered for those who demand thunderous, impactful, bottomless bass while retaining full system clarity, Descend Series subwoofers are the ultimate overachievers.
