Definitive Technology has announced the Descend Series subwoofers. The new line consists of four high-performance models that usher in a new design architecture from Definitive Technology called 3XR, which employs dual passive radiators coupled to an active drive unit to triple the bass-producing radiating area. The 3XR architecture generates deeper bass and higher output levels due to the unique design of the two radiators, which are the same size as the woofer. And because this proprietary design does not rely on conventional bass ports, Descend Series subwoofers do not produce any chuffing or distortion that plagues ported models. Each model also features custom amplification to deliver dynamic and extended bass.
To easily build into any system, all four models boast connectivity via LFE, while the 12- and 15-inch models also boast a stereo line level RCA input. All four models are available in non-resonant cabinets finished in Midnight Black and two models (DN8 and DN10) are also available in Glacier White.
The Definitive Technology Descend DN15 and DN12
The Definitive Technology Descend DN15 and DN12 are ultra-high-performance 15-inch and 12-inch subwoofers designed for reference music systems and significant home theater applications. Each model is powered by a custom-built Definitive Technology 1500-watt Class H sliding rail amplifier, which handles both transient peaks and super low bass extension to below 20 Hz (in the case of the DN15). To produce smooth and precise reproduction from the deepest bass-heavy content, 3XR Architecture pairs custom drivers with a same-sized, dual-radiator array.
Another proprietary innovation found within the DN15 and DN12 is Intelligent Phase Control, which provides a full 360 degrees of customizable phase adjustment. To better align phase, most subwoofers offer either a polarity toggle between zero or 180 degrees, or an all-pass filter that can cause smearing. Intelligent Phase Control enables listeners to further fine-tune their subwoofer’s phase by combining the best elements of a polarity toggle, but with greater granularity, along with an all-pass filter, while automatically aligning the phase adjustment with the low-pass filter to support the entire audio system most precisely.
The DN15 and DN12 also employ an advanced 56-bit Digital Signal Processor (DSP) that improves bass response and overall sound quality while closely monitoring the woofer system to prevent potentially harmful distortion at ultra-high volumes. In addition, the DN15 and DN12 have three built-in performance EQ modes (Flat, Deep, and Loud). The out-of-the-box “Flat Mode” is a great starting point for level adjustment and system calibration. “Loud Mode” provides listeners with the most output level and is excellent for big action movies and cinematic sound effects, while “Deep Mode” offers the lowest frequency extension possible, perfect for music reproduction, particularly passages with wide dynamic range.
Each model comes with a slim remote and built-in front LED display, enabling users to adjust volume level, phase, and EQ with visual confirmation from the listening position. Further, each model features a 12V trigger and IR pass-through for integration with popular control systems to achieve full functionality and custom adjustments from anywhere in the room.
The Definitive Technology Descend DN10 and DN8
The Definitive Technology Descend DN10 and DN8 are high-performance 10-inch and 8-inch subwoofers that offer extension and detail from music and home theater soundtracks. The DN10 and DN8 are powered by a 500-watt Class D amplifier matched with custom drivers and the same 3XR dual-radiator architecture found in the 15-and 12-inch models.
To ensure the DN10 and DN8 are tuned to the rest of the system and room acoustics, each model features built-in controls to adjust output level, low-pass filter and phase (0/180 degrees). The DN8 has a small, 1-foot-squared form factor that tucks away discreetly.
Availability and Warranty
The Definitive Technology Descend Series subwoofers include a 5-year warranty on drivers and cabinets and 3 years on amplification and electronics, and are currently available for sale at DefinitiveTechnology.com and authorized Definitive Technology retailers.
