Biamplified Reference Monitors.
Professional Accuracy, Clarity and Performance in an Affordable Powered Monitor.
By combining our expertise in reference monitor design with our proven
track record in studio amplification, Alesis' new M1 Active™
Biamplified Reference Monitor offers the incredibly accurate response
that perfectly translates to every playback system. Its internal active
crossover and custom-designed dual amplifiers ensure an extremely
consistent performance under a variety of different studio conditions
and program material. The result is a broad, extremely flat frequency
response, clear imaging with a wide sweet spot, high power handling and
detailed high- and mid-frequency response that only a professional
powered monitor can deliver.
Features
Custom Drivers Designed For Active Monitoring
The M1 Active's woofer and tweeter were specifically designed for the most linear, lowdistortion response in powered monitoring applications. Its 6.5" woofercone is formulated from non-woven carbon fiber. It's a material thathas been used for the skins of combat aircraft wings, since it offershigh 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.
Active Bi-Amplifiers and Electronic Crossovers
Two audiophile-quality amplifiers-a 75 watt woofer amp and a 25 watt
tweeter amp-were developed for the M1 Active, 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. Also, the special
time alignment circuitry that's been added to the tweeter section of
this 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 less advanced powered speakers.
Attractive Cabinet Design with Dual Ports and Offset Tweeter
In developing the M1 Active, the Alesis engineering team discovered that
dual font-mounted ports provided the fastest, most coherent and
extended low frequency augmentation. Also, the unique offset design of
the high frequency driver allows for the flattest frequency and power
response in a speaker that offers such wide dispersion. The M1 Active's
attractive mirror-imaged, charcoal- toned cabinet and magnetically-shielded drivers allow for placement in close proximity
with computer or video monitors, and offers the added benefit of
blending beautifully into your studio's decor without being obtrusive.
They may be mounted in either a horizontal or vertical placement to
best fit your studio's requirements.
The Alesis M1 Active™
With the lineage of our TEC Award-winning Monitor Onet Studio Reference
Monitor, Alesis speakers have already become a standard in project and
professional studios around the world. If you're looking for the same
great accuracy and detailed response in a powered system that's truly
affordable, the answer is clear: the new M1 Active from Alesis.
