chapter 1 About the Monitor One Your new Alesis Monitor One Mk2™ 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. The original version was a winner of the prestigious TEC Award and became an instant favorite among professional engineers and studio owners. The "Mark 2" edition of this famous product makes a few design and material changes that make it even better while preserving the classic sound of the original. This speaker system uses a proprietary 6.5" high-power low frequency driver with a special mineral-filled polypropylene cone. The cone is suspended by a highly damped linear rubber surround with a special edge design to improve midrange frequency response. It has a 1.5" diameter voice coil wound on a high-temperature Kapton former, with a long-throw voice coil and magnet. The 1" high frequency driver employed has a soft natural silk dome and is ferrofluid-cooled. A newly-designed waveguide surrounding the dome improves the polar pattern, giving a smoother off-axis response. Both drivers are now magnetically shielded, allowing the speakers to be mounted close to video and computer screens without distorting the color images. The system's passive crossover network uses low dielectric loss nonpolarized capacitors and an oversized low-loss low frequency inductor. Both high-pass and low-pass sections are true second-order filters (12 dB/octave) with a crossover at 2 kHz. 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 is nullified by the effect of turbulence in the restricted port tube at loud sound levels.
