Alesis M1 Active MKII biamplified reference Studio monitor. Accurate response, excellent imaging, flat frequency range. 6.5 non-woven carbon fibre woofer. 1 silk-dome tweeter. Audiophile-quality internal 75W (LF) and 25W (HF) amplifiers. Magnetically shielded for use near computers.
The Alesis M1 Active MkII woofer and tweeter were specifically designed for the most linear, low distortion response in powered monitoring applications. The M1 Active MkII's 6.5 woofer cone is manufactured from non-woven carbon fiber a meterical that offers high tensile strength and low weight. Carbon fiber is 25% lighter than polypropylene, the most common driver material, and provides quicker transient response in the low frequency range for superb bass response as well as a vast improvement in the detail of critical upper-mid frequencies. The M1 Active MkII's 1 tweeter dome is made of pure silk, which offers a natural response that aids in preventing ear fatigue during long mix sessions. The M1 Active MkII also features an internal pole piece mounted phasing plug and is ferrofluid cooled to maintain the best balance of transient response to power handling.
Two audiophile amplifiers, a 75 watt woofer amp and a 25 watt tweeter amp, were developed for the M1 Active MkII, along with 8th order high- and low-pass electronic crossover filters. The crossover point was carefully chosen at a low 1500Hz, and produces an extremely wide dispersion zone as well as low midrange coloration. Special time alignment circuitry of the M1 Active MkII's crossover allows the output of frequencies from the high and low drivers to occur in perfect synchronization, avoiding the time smear that's typical in some other powered speakers. - Great accuracy and detailed response in a powered system that"s truly affordable
