Since opening our showroom in December, there has been one brand we stock that has clearly drummed up the most interest; a brand that seems to be generating a big following amongst audiophiles, musicians (such as Pink Floyd and The Rolling Stones) and the hi-fi press of late.
ATC Loudspeaker Technology was formed in 1974 by Billy Woodman. From the outset the main focus of the company has been the quality; the majority of their components are handbuilt in-house. This really is a first for a UK speaker manufacturer, as most commonly companies will simply buy their units from other companies and put them into their systems or get the parts manufactured under licence. A company manufacturing their own components is extremely rare. ATC even hand wire their drive units.
Why We Chose ATC
Listening to ATC speakers is a joy. They give a truly amazing neutral presentation of the music; it is an effortlessly natural sound. ATC speakers are fantastic all-rounders, it is extremely difficult to find downsides to their sound. They are clear and engaging with brilliantly controlled bass and beautiful highs.
As soon as you push play, you know why the reputation of ATC Loudspeakers has become so great and continues to grow. This is a company that has been innovating loudspeaker design for 40 years and it doesn’t look like that is going to stop any time soon.
Inside ATC Loudspeakers
The majority of ATC speakers (The ‘SL’ range) come equipped with ‘Super Linear’ technology. This is basically a method of eliminating the distortion of the input signal called ‘Hysteresis’ caused from the non-linear magnetic properties of the steel regions around the voice coil. ATC has developed ‘Super Linear Magnetic Material (SLMM)’, a material that has high magnetic permeability and saturation levels and low electrical conductivity. Using the SLMM in their loudspeakers instead of steel has had a dramatic effect on the distortion. Ambient sounds and low level effects that were previously masked are now clearly audible and provide an enhanced sense of realism. The articulation of male vocals is markedly improved and pianos really shine.
Another feature of the latest ATC range that is unique is the new SH25-76 tweeter, if you speak to anyone at ATC you get a real sense that a huge amount of effort had gone into the development of this tweeter, and that they are supremely proud of it. For those of you who are not up on your speaker design, very few companies in the UK actually manufacture their own tweeters, more often than not companies will just buy in tweeters from foreign manufacturers and fit them into their speakers. Manufacturing the tweeters in-house has now given ATC the ability to fine tune the tweeters to exactly how they want them, and push the ATC sound to another level.
The tweeter shares technology with ATC’s famous soft domed mid-range drive unit and employs a unique dual suspension system suppressing rocking modes even at high power output levels. The ATC configuration of a short edge-wound voice coil in a long, narrow magnetic gap ensures exceptionally low distortion throughout its operating band and removes the need for ferrofluids, which can dry out over time, compromising performance. This is a unique concept which has proved incredibly successful for ATC. The SM75-150 soft dome mid-range driver has been utilised in ATC speakers for many years and has really set the bar for performance levels. With a usable frequency response for 300Hz to 4000Hz. It is able to handle this very important range without any crossover.
