Tannoy definition Subwoofer Wall

About PSB Alpha Subseries 450

• The Definition Subwoofer shares the same purity of purpose and contemporary design that embodies all Definition series loudspeakers. Seamlessly blending power and passion with detail and control, the Definition Subwoofer delivers smooth LF extension with music and thunderous Low Frequency Effects with movies. A design of simplicity and refined power, a 1KW amplifier drives an opposing pair of 300mm (12in) long throw metal-cone drivers in a substantial plywood cabinet. Definition Subwoofer is designed and engineered with Tannoy’s fundamental principles of precision and articulation at its heart.
• At the heart of the Definition Subwoofer is a cutting edge 1000Watt 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 are mounted on the front panel for simple user control.
• To handle the extreme power, the Definition Subwoofer uses two 300mm (12inch) 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 posttonic motion at high levels and good heat transfer properties allowing them to be driven very hard for extended periods of time. The drivers’ dies cast aluminium chassis has been designed to afford maximum driver venting to maximise excursion.
• The substantial subwoofer cabinet is finely constructed from Tannoy’s signature birch-ply laminate sourced from cooler, slowing growing regions. 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. Definition Subwoofer offers a flexible suit of connections allowing one or more subs to be connected in the system and compatibility with both phono RCA and balanced XLR signals.
• Each Definition Subwoofer is hand finished in a choice of high gloss black or high gloss lacquered real wood veneers to match the Definition loudspeaker range. Each Definition Subwoofer offers heavy duty CNC machined aluminium feet for optimum stability and convenient front mounted rotary controls with LCD display.
