CHAPTER 1: ABOUT THEMONITOR ONE
Your new Alesis Monitor One™ Studio Reference Monitors will
deliver accurate mixes in near-field digital and analog studio
monitoring applications. The Monitor Ones offer wide frequency
response, accurate transient reproduction, clear imaging and high
power handling capability and were designed by experts with
decades of experience in professional loudspeaker design.
This speaker system uses a proprietary 6.5" high-power low
frequency driver with a special mineral-filled polypropylene cone,
a highly damped linear rubber surround and a 1.5" diameter voice
coil wound on a high-temperature Kapton former. The 1" high
frequency driver employed has a soft natural silk dome and is
ferrofluid cooled. The system's crossover network uses low
dielectric loss non-polarized capacitors and an oversized low-loss
low frequency inductor. Rear panel connections are made via 5-
way binding posts suited to large diameter wires as well as
banana plugs.
The cabinet design uses Alesis' exclusive SuperPort™ speaker
venting technology. Most small speakers used for near-field
monitoring give disappointing results in their lowest frequency
range. They are either sealed (which limits the amount of air the
driver can move) or have an undersized vent whose function at
low frequencies and high acoustic output is nullified by the effect
of turbulence in the restricted port tube. The Monitor One's large
folded SuperPort overcomes this limitation by minimizing vent
turbulence at high air velocities, thereby ensuring that the
enclosure tuning remains stable, the acoustic output remains
linear during heavy low frequency attack transients, and that the
reactive load above and below box resonance seen by the driving
amplifier does not dynamically shift in frequency. This all
translates to tighter bass with higher definition.
The Monitor One's 4 ohm load impedance takes advantage of
today's modern professional amplifiers which are generally capable
of a 1-3 dB increase in output power with 4 ohm loads over their 8
ohm ratings. The result is a similar increase in the Monitor One's
acoustic output over conventional 8 ohm monitors.
Reliable handling of this additional acoustic output is ensured by
the Monitor One's substantial power handling capability. Typical
near-field monitors are rated at 50-60 watts maximum whereas the
Monitor One carries a 120 watt continuous power rating and has
