This is the DC4, the entry-level model in the new Tannoy Revolution Signature range. Using the same Dual Concentric drive unit as the company's little Autograph Mini speaker, it features the ultra-rigid curved-wall enclosure found throughout the new line-up, which extends to floorstanding speakers and dedicated centre-channel models.

Revolution Signature comprises two speaker line-ups: the DC4 models use a 4in/10cm dual concentric drive unit, matched with a bass units of the same size in the floorstanders and centre speaker, while the the bigger DC6 models have – you've guessed it – 6in/15cm drivers.

All the speakers also feature Tannoy's innovative driver chassis grounding terminal, designed to reduce radio-frequency interference in the system by earthing the speaker to the amplifier.

The new enclosures, which are available in Light Oak or dark Espresso hand-finished real wood veneers, are designed to eliminate internal standing waves, and use concealed multipoint fixings for the die-cast metal driver chassis, metal trims and sculpted ports. High-quality biwirable crossovers are used, and all the internal wiring is silver-plated oxygen-free copper.

The £600-a-pair DC4 speakers have a 19mm titanium dome tweeter in Tannoy's Tulip WaveGuide at the centre of their 10cm driver, the DC4T floorstander adds that extra bass driver and costs £800/pr, and the DC4LCR uses twin bass drivers straddling the Dual Concentric driver, and sells for £400.

A 25mm tweeter is used at the centre of the bass unit in the £800/pr DC6 speakers, while the DC6T floorstanders sell for £1000/pr and the DC6 LCR is £600.

The Tannoy Revolution Signature range is available now.

In associated news, Tannoy parent company TC Group, which is based in Denmark, has announced that it is merging with guitar manufacturer Gibson. When the merger is completed – the end of February is the expectation – Tannoy will be part of the renamed Gibson Guitar Corporation.
