ATC Loudspeaker Technology celebrate their 30th anniversary with a very special edition of their highly acclaimed SCM50 ASL loudspeaker, designed to provide a reference standard for all current and future audio formats. This exceptionally accurate three-way monitor incorporates the latest versions of all three drive units, featuring further developments of ATC's proprietary Super Linear high gauss magnet and Soft Dome technologies, which are responsible for the high power output, low distortion and wide horizontal dispersion of this anniversary speaker.

The 'Anniversary Active 50 Tower' speaker incorporates a new ultra low noise fully discrete version of ATCs grounded source topology ® 350watt three-way amp pack operating in class A up to 2/3rds of output, giving 200watts to bass driver, 100watts to mid-range driver, and 50watts to HF driver. The noise floor of minus 90dB, gives this speaker exceptional dynamic range and is probably the lowest noise level achieved by any domestic loudspeaker in production today.

The 30th anniversary tower will be the first version of this exceptional loudspeaker to be produced as a floor standing model. The already outstanding bass performance of the standard SCM50A is considerably enhanced by an increase of approximately 15% in the internal cube of the tower enclosure.

The new "Anniversary Active 50 Tower" is fully veneered in a beautiful honey coloured multi-grained American Burr Magnolia. With a rich 'piano' high gloss finish. This spectacular tree is noted for the rich depth of colour and the grain pattern of beautiful swirls and burls. With the veneers taken from close to the root of the tree, the intricate shapes and colourations are unique to each speaker. Removing the dark blue front grille, reveals a titanium finished baffle and dome wave guide. With this finish also applied to the amp pack on the rear of the speaker.

An aircraft grade highly polished aluminium band below the speaker grille enhances the appearance of this visually and sonically outstanding speaker.

The supplied opalescent non-resonant bass plate incorporates optional three point heavy duty polished steel spiked feet for firm coupling to concrete or wooden floors. The supplied matching 1" circular, centred , polished steel discs are felt padded, to protect polished floors, where required.

Created in stereo pairs the LIMITED EDITION 30TH ANNIVERSARY SIGNATURE SCM50 ASL '50' TOWER is also available in passive form, without onboard amplification. Single speakers for multichannel installations are available.

Superb performance and appearance will give the fortunate owners of this speaker, many years of pleasure, with the knowledge of the speakers exceptional build quality, professional heritage and a 6-year warranty, total peace of mind is assured.
