Custom Drivers Designed For Active Monitoring
The M1 Active's woofer and tweeter 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.
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.
