EL150SL Active

About the EL150SL Active

The ATC EL150SL Active loudspeaker is a three-way active speaker system designed with ATC's proprietary drivers: a 25mm high-frequency driver, a 75mm soft dome midrange driver, and a 375mm super linear bass driver. It features a wide frequency response of 25Hz to 22kHz (-6dB) and a matched response accuracy of ±0.5dB. The cabinet is designed to minimize edge diffraction and internal resonance, ensuring clear and precise sound imaging with a horizontal dispersion of ±80° and vertical dispersion of ±10°. The active version uses the P6 amplifier, a high-performance Class AB dual-mono power amplifier delivering 350 watts per side (200W LF, 100W MF, 50W HF). The system is known for its low distortion, high power handling (suitable for amplifiers from 100 to 1500 watts), and lifetime guarantee for the original owner. The EL150SL Active is now discontinued, with the SCM150ASLT LE as its current equivalent.
