Definitive Technology Descend DN10

Features

3XR Architecture: The Definitive Technology DN10 powered subwoofer's unique 3XR Architecture means it delivers all the bass you need and then some, performing significantly louder and clearer than most other 10" powered subwoofers. The unique 3XR Architecture provides triple the bass-producing radiating surface area of a traditional ported subwoofer. This extra surface area moves more air, resulting in massive low-end bass performance. Because the DN10 has 3x the bass-radiating surface area as similar-sized ported powered subwoofers, it produces more bass from the same sized enclosure. Since the 3X Architecture design doesn't use ports, it also provides crystal-clear sound with no port noise distortion.

Dual Passive Bass Radiators: As the core technology behind the Descend Series' 3XR Architecture, dual opposing side-firing 10" passive bass radiators enable the DN10 powered subwoofer to play as loud and low as a ported sub without unwanted port noise distortion. The Definitive Technology DN10 delivers a smooth frequency response like a sealed sub, but with the "port-like" ability to play louder and lower in a smaller enclosure.

10" Long-Throw Woofer: In addition to the dual opposing side-firing 10" passive bass radiators, the Definitive Technology DN10 powered sub employs a front-firing 10" long-throw active woofer powered by a built-in, custom Class D amplifier rated at 200 watt (RMS) / 500 watt (Peak) for consistently deep, impactful, dynamic bass for home theater and music systems.

Custom Class D Amplifier: The custom Class D amplifier used in the Descend Series powered subwoofer was designed to get the most out of Descend's unique 3XR Architecture. Optimized for efficiency and a strict avoidance of distortion, the custom Class D amplifier delivers consistently dynamic performance with the ability to push hard for maximum impact when needed. This custom amplification design provides the DN10 with enough power and efficiency to play as low as 30Hz without taking up a ton of space. The custom class D amplifier used in the DN10 powered subwoofer is rated at 200 watt (RMS) / 500 watt (Peak).

Rear-Panel Controls: The rear-panel of the Descend Series DN10 powered subwoofer features controls to help you fine-tune the phasing, volume, and low-pass crossover of the sub to ensure it blends perfectly with your system. As a result, you'll always have a fully balanced, smooth bottom-end regardless of your system or room.

• Volume Level: You can adjust the volume level of the power subwoofer to ensure perfectly proportioned bass for your audio system and your room.
• Low Pass Crossover: The Low Pass Crossover ensures that only the frequencies intended to be reproduced by the DN10 get through to the powered subwoofer. The Low Pass Crossover can be set between 60Hz and 120Hz.
• Phase Switch: Adjusting the DN10's Phase Switch ensures the powered subwoofer's timing is tightly synced with the rest of your system's speakers, presenting pinpoint-accurate audio for movies and music soundtracks. The Phase Switch can be set to 0 or 180 degrees.

LFE and Speaker-Level Inputs: The Definitive Technology DN10 powered subwoofer is outfitted with both LFE and speaker-level inputs for flexible connectivity.

• LFE Input: The LFE input consists of a mono-RCA jack which is not affected by the powered subwoofer's low pass crossover. It is designed to connect the DN10 to an AV receiver or preamp/processor which features a LFE output and bass management. Your AV receiver or preamp/processor's bass management setup will be utilized to apply a low pass crossover to the powered subwoofer.
• Speaker-Level Input: The speaker-level input consists of 5-way binding post terminals that accept bare wire (up to 12AWG), pin-connectors, spade-lugs, and banana plugs (single or dual). The speaker-level inputs allow the powered subwoofer to be connected to your AV receiver's main speaker outputs. The setting of the low pass crossover is applied to the signal received through speaker-level inputs.

Placement Options: There are some general guidelines that you should keep in mind when positioning the Definitive Technology DN10 powered subwoofer in your room.

• For best results, place the powered subwoofer on the same side of the room as your front speakers. Placement near walls and in a corner will increase the powered subwoofer's output, but the sound may be "muddy" or "boomy". Moving the subwoofer even a foot or two can dramatically change the bass output and quality. Experiment with subwoofer placement to achieve the highest performance.
• An acoustic effect called "standing waves" or "room modes" may cause uneven bass at various locations throughout the room. This phenomenon is a function of the dimensions of the room and not due to the design of the subwoofer. If there is less bass at the main listening position than at other areas of the room, move the powered sub until you hear full bass at the main listening position.
• The subwoofer may be placed inside a cabinet, provided there is a clearance of at least 2" around the front, back, sides and top of the powered sub. The front of the cabinet should be completely open or covered with an open mesh grille, screen, or cloth.

Auto Power On/Off: The Definitive Technology DN10 powered subwoofer will turn on when it receives an audio signal at its LFE or speaker level inputs. If no signal is sensed for a period of time, the powered subwoofer will automatically turn off.

Detachable AC Power Cord: The Definitive Technology DN10 comes with a detachable 6' AC power cord that will need to be plugged into the back of the powered sub and into an AC wall outlet or surge protector/line conditioner (sold separately - see Accessories Tab).
