All of the Definition speakers feature Tannoy’s Dual Concentric drivers (hence DC), which place a 1in Tulip WaveGuide tweeter within the throat of the larger mid/bass driver, powered by a neodymium motor (ferrite inside the DC6). This enables the high, mid and bass frequencies to emanate from a single point source, which is said to help timing and create a wider imaging ‘sweet spot’.
The size of the mid/bass cone (crafted from treated paper pulp with a rubber surround) is the main difference between the speakers in the range – the DC8T’s cone is 8in, DC10T’s is 10in and there’s a new 6in version in the DC6 LCR. The DC8s sport just one of these DC drivers, but in the DC8T it’s joined by an 8in bass-only driver designed to lend extra depth when used without a subwoofer. The drivers are coupled to the cabinet using a unique bracing mechanism that incorporates Tannoy’s Differential Material Technology (DMT) to improve rigidity.
The DC6 LCR’s 6in DC driver is flanked by a 6in bass driver and passive radiator. Although this centre could have matched the punch and drive of the other speakers using the same single DC driver and a rear-ported design, Tannoy thought it would be inappropriate for a centre speaker as it’s likely to be installed in a TV stand or against the wall – so they went for a sealed cabinet design with the dual driver/radiator arrangement instead.
Also, on the features front, the crossovers in each speaker have been subjected to Deep Cryogenic Treatment, whereby the components are supercooled to -190°C and thawed. This helps to reduce structural ‘stresses’ in the component materials, in turn improving signal transfer and detail resolution. If it’s good enough for Walt Disney, it’s good enough for us.
Add to that silver-plated, oxygen-free copper internal wiring across the board, low-loss laminated core inductors and audiophile grade polypropylene capacitors in the crossover network and you have yourself a meticulously crafted set of high-end speakers.
