SCM50ASL Anniversary

About the SCM50ASL Anniversary

The **ATC SCM50ASL Anniversary** is a limited‑edition, active 3‑way tower loudspeaker based on ATC’s SCM50 design and produced as an Anniversary “Special” version of the standard SCM50ASL. It uses ATC’s classic driver complement: a **25mm soft‑dome tweeter**, **75mm SM75‑150S soft‑dome midrange**, and a **234mm (9") Super Linear bass driver**, coupled to an active tri‑amplifier pack delivering **50W to HF, 100W to MF, and 200W to LF** via active electronic crossovers around 380Hz and 3.5kHz. The built‑in amplification is discrete MOSFET Class A/B with a Class‑A input/voltage gain stage and active filters, designed for low distortion and precise control of each driver. Frequency response for the SCM50‑based active systems is specified at approximately **62Hz–17kHz (±2dB)** and **35Hz–22kHz (±6dB)** with matched pair tolerance within **±0.5dB** and **maximum continuous SPL of 112dB at 1m**. The Anniversary tower shares these core acoustic and amplifier characteristics but is packaged in a **floorstanding cabinet** with an exclusive baffle, plinth and spike assembly, and high‑gloss "piano" lacquer finish with metal trim, differentiating it from the Classic stand‑mount SCM50ASL. The loudspeaker is **balanced XLR‑input**, employs active electronic crossovers and phase‑coherent dispersion, and carries ATC’s **6‑year warranty** when purchased through authorized dealers. It is voiced for **high accuracy, transparency and wide dynamic range**, making it suitable for both professional monitoring and high‑end domestic listening. ATC now lists the **SCM50 Anniversary** in its Legacy Editions as **discontinued**, noting the **SCM50 SE** as the current equivalent model, so the SCM50ASL Anniversary tower is no longer in production.
