The ATC SCM 150 SL can produce high-quality sound with a maximum and continuous sound pressure of 117 dB SPL. The housing of the Classic series speakers, the surface of which is finished with precious wood veneer, has a classic design of strict cabinets. The acoustics of the ATC SCM 150 SL also feature an improved bass reflex port and wide symmetrical dispersion.
The ATC SCM150ASL Professional Acoustics is a new active three-band reference-level monitor that can play both high-quality music and movie soundtracks in an unsurpassably high sound quality.
A powerful bass вкшмук with a paper diffuser, 314 mm in diameter, manufactured using proprietary SLM technology, developed back in 1986, is responsible for the low-frequency component of the sound in this model. This technology eliminates the eddy currents that occur on the surface of the metal parts of the driver, which causes nonlinear sound distortion.
The speakers are equipped with a Seas Excel dome tweeter with a diameter of 25 mm, a silver wire coil and a powerful magnetic system consisting of two neodymium magnets. Next comes the famous horn-dome midrange driver, equipped with a 75 mm diaphragm, a 75 mm sound coil, and a massive magnetic system weighing more than 7 kilograms.
The ATC SCM 50SL speakers are a kind of benchmark for home acoustics, which many professional record companies are also guided by.
