Alesis M1 Active MkII Speakers

The woofer and tweeter in the M1 Active MkII were specifically designed for the most linear, low distortion response in powered monitoring applications. Its 6.5" woofer cone is formulated from non-woven carbon fiber. It's a material that has been used for the skins of combat aircraft wings, since it offers high tensile strength and low weight. In fact, carbon fiber is 25% lighter than polypropylene (the most common driver material) and hence 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's 1" tweeter dome is made of pure silk, which offers a natural response that aids in preventing ear fatigue during long mix sessions. It also features an internal pole piece mounted phasing plug and is ferrofluid cooled to maintain the best balance of transient response to power handling.
