August 28, 2012 - The Definition Subwoofer brings ultra-low frequency sound reproduction to the award winning Definition loudspeaker series. Sharing the same purity of purpose and contemporary design that embodies all Definition series loudspeakers, the Definition Subwoofer blends power and passion with detail and control. Designed to deliver thunderous Low Frequency effects with movies and musically accurate LF extension into sub-bass frequencies, the Definition Subwoofer delivers class leading authority and control.
A design of simplicity and refined power, a 1KW amplifier drives an opposing pair of 300mm (12 inch) long throw metal-cone drivers in a substantial plywood cabinet. DSP-based processing and user controls in the digital domain offer exceptional installation flexibility alongside the subwoofer’s class leading LF extension and high maximum SPL. The Definition Subwoofer is a thoroughbred bass-only loudspeaker designed and engineered with Tannoy’s fundamental principles of precision and articulation at its heart.
In keeping with the Definition range, the substantial subwoofer cabinet is finely constructed from Tannoy’s signature birch-ply laminate. Tannoy specifies that this timber is sourced from cooler, slowing growing regions to further improve the natural acoustic properties of the enclosure. Constructed of 25mm thick laminate, the cabinet uses a mix of flat and curved panels to improve rigidity as well as disperse internal reflections and standing waves. Panel joints and internal bracing follow the same techniques and craftsmanship used in Tannoy’s flagship loudspeakers, creating the perfect enclosure for low frequency reproduction.
At the heart of the Definition Subwoofer is a cutting edge 1000 Watt Class D amplifier with high speed switch mode power supply. Boasting exceptionally low Total Harmonic Distortion (less than 0.05%), this amplifier delivers massive dynamic power to control the twin metal-cone LF drivers. The amplifier module is mated to a powerful Digital Signal Processing (DSP) engine that offers user controls entirely in the digital domain for the most accurate set-up and LF response. A multifunction rotary control device and LCD display is mounted on the front panel offering convenient access for adjustment to volume and all other settings.
To handle the extreme power, the Definition Subwoofer uses two 300mm (12 inch) aluminium cone drivers arranged as an opposing pair and mounted either side of the ply-wood cabinet. After extensive testing aluminium drivers were specified for their true pistonic motion at high levels and good heat transfer properties allowing them to be driven very hard for extended periods of time. The drivers’ die cast aluminium chassis has been designed to afford the utmost driver venting to maximise excursion.
The Definition Subwoofer offers a flexible suite of connections allowing one or more subs to be connected in the system and compatibility with both phono RCA and balanced XLR signals. Two phono RCA and two balanced XLR inputs are provided to feed the DSP engine and on-board amplifier, with stereo inputs combined into a single LF feed. Twin RCA and XLR outputs pass through the source input to feed to further subwoofers in the room.
Each Definition Subwoofer is hand finished in a choice of high gloss black or high gloss lacquered, real walnut or cherry wood veneers to match the finishes within the rest of the Definition loudspeaker range. The deep gloss finish is polished mirror-smooth and the subtle aluminium trims reflect the contemporary style across the entire Definition range. Heavy duty CNC machined aluminium feet provide optimum stability.
The Definition Subwoofer joins the Definition DC6LCR, DC8, DC8T, DC10T and the new DC10A to augment Tannoy’s flagship contemporary loudspeaker range.
