Alesis M1ACTIVE 520

The Alesis M1 Active 520 is a newly designed, affordable, high-precision active reference monitor with Bass Density control and EQ. The M1 Active series offers incredible definition and flat frequency response from the high-precision drivers and a professionally crafted crossover. The cabinet and drivers have been redesigned for a bold new look and even greater sonic clarity.

The M1 Active 520 has a 1 inch thick front baffle, which minimizes speaker resonance, and the visually stunning acoustic waveguide evenly disperses high-frequency sound across your control room. The M1 Active includes new Bass Density technology, which allows you to tailor these monitors to any room's acoustics. The distinctive top-mounted power/clip indicator lets you know if the speaker is clipping.

The M1 Active 520 features a 75-Watt amplifier and a 5 inch low frequency woofer.

Woofer : 5”
Lightweight, magnetically-shielded, ultra-stiff polypropylene cone with rubber surround.
Tweeter : 3/4”
