Tannoy has been around for a very long time. Indeed, in the UK, a public address loudspeaker is often called a "Tannoy".

But this brand is not just venerable; the Tannoy Definition DC10T loudspeakers are exceptionally elegant.


Imagine the most beautifully finished, high-gloss, wood-grain piano that you've ever seen, and that's what you can expect to see when you open the carton containing a Tannoy Definition DC10T loudspeaker. Absolutely gorgeous in finish, they also are extremely solid in construction. Each weighs nearly 35 kilograms.

Most speakers these days present a fairly narrow face to the room. These don't. In order to accommodate their two 250mm drivers in each enclosure, they are actually about 340mm wide. The sides of the enclosures curve to a narrower rear. On the supplied spikes, each stands at about 1125mm tall.

At the bottom of the two large drivers in each enclosure is a bass driver. Really, that's all it does; it is responsible for the frequencies from the loudspeaker's bottom end of 30 hertz up to 200 hertz, where it hands over to the top, 250mm unit.

That top one looks obviously different, because it has at its centre a hole in which resides a 25mm titanium dome tweeter. Yes, another concentric driver. Tannoy has been doing this for a very long time, though. An advantage of this is that at the crossover point (1400 hertz), there is very little opportunity for destructive interference between the drivers, due to different path lengths to the ears. The tweeter is pushed back quite a way into the centre of the larger driver, primarily in order to "time align" the drivers. Tweeters tend to be more responsive to the signal than the larger drivers, so, by making this adjustment, the wave front of the lower and upper frequencies from the same instrument can be aligned with each other.

Tannoy talks about some strange stuff, such as freezing the crossover network to -190 degrees Celsius in order to "reduce the internal stresses in the microstructure" of it. Sounds a bit like one of those mystical practices that some hi-fi people get up to. Still, we don't suppose that it does any harm.
