Alesis M1 Active MkII for Accurate Pro Monitoring!
By combining their expertise in reference monitor design and proven
track record in studio amplification, Alesis' new M1 Active MkII
Bi-amplified Reference Monitor offers the incredibly accurate response
that perfectly translates to every playback system. The M1 Active
MkII's 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.
The Woofer & Tweeter
The M1 Active MkII 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 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.
Power
Two audiophile-quality 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. Also, special time
alignment circuitry that's been added to the tweeter section 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.
Perfect For Your Studio
In developing the M1 Active MkII, 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 MkII'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. The M1 Active MkII may be mounted in either a horizontal or
vertical placement to best fit your studio's requirements.
