Tannoy Revolution Signature DC4 LCR

The time coherent, point source Dual Concentric^TM driver is effectively two drive units, HF and MF/LF, properly merged into one; ensuring there is no loss of energy in the crossover region. The high rigidity chassis, with multi-point fixings for optimal contact with the baffle, minimises vibration and delivers fast tuneful bass, while the rigid multi-fibre paper pulp cone provides accurate bass and dynamic midrange with excellent intelligibility.

Key to the acoustic performance of this award winning drive unit is the WideBand^TM tweeter technology. Using a high rigidity titanium dome with neodymium magnet assembly coupled to a rear acoustic cavity, the driver delivers low colouration and meticulously detailed, spacious and airy detail. The substantial magnet assembly is shielded to prevent colour fringing effects when placed close to screens.

Crossover design:
Great care has been taken over the component topology; kept simple in layout for maximum signal transfer and to minimise interaction between components. Tannoy DMT^TM (Differential Material Technology) is used to damp the audiophile grade polypropylene capacitors in the HF feed and low loss laminated core inductors have been selected for the LF section. The internal wiring is silver plated high purity oxygen free copper, with high current bi-wire terminals.

The addition of an extra fifth terminal provides grounding for the drive unit chassis, voice coil and speaker cable to reduce the pick up of airborne RF; thus eliminating any feedback interference that can adversely affect the performance of the source electronics in any audio system.

Cabinet construction:
The high rigidity MDF construction, with its extensive internal bracing, minimises âcabinet effect colouration and contributes to the clean detail and speed of the presentation. DMT^TM (Differential Material Technology) a special Tannoy bracing mechanism, is used between the back of the drive unit and the cabinet to further control vibration, resulting in enhanced resolution of fine detail. The curved wall trapezoidal cabinet construction minimises resonances and internal reflections, while floor standing models are also equipped with spikes for optimum stability and vibration reducing contact with the floor surface; all of which are factors in improving stereo imaging.
Clean and contemporary, the hand finished cabinets are available in a choice of Espresso or Light Oak real wood veneers to match traditional and modern interiors. The beautifully integrated brushed aluminium trims, with discreet logo and branding, complete the cool and fully integrated design.
