Sennheiser Electronic Corp. (SEC) will be showcasing the
Klein + Hummel (K+H) O 300 D three-way active studio monitor system at the upcoming
119th AES Convention in New York. As of July 1, 2005, SEC assumed
distribution responsibility for the U.S. and Latin American markets.
The compact O 300 D draws on K+H's extensive monitor design experience to
deliver an extremely flat frequency response. Three drivers, each powered by a high-performance amplifier
exactly matched to the driver's technical requirements, are mounted in a
front baffle of Low Resonance Integral Moulding. Waveguides machined into
the new, dense LRIM material provide optimal dispersion while also
minimizing time and phase coherency problems at the crossover frequencies.
The eight-inch (210mm) long-excursion voice coil cone woofer is made of a
special lightweight polypropylene material with excellent self-damping
properties and delivers tight, articulate bass that is strikingly clear,
detailed, and natural, particularly in transients according to the company. A three-inch (76mm)
diameter voice coil, treated fabric dome driver handles the mid-range. With
a much lower mass than cone drivers, it has the advantage of being able to
achieve superior impulse response and extremely uniform amplitude response.
The high-frequency driver is equipped with a titanium/fabric dome that
combines the transparency of a titanium dome with the low-distortion of a
fabric dome and is finely matched to its elliptical waveguide to ensure
exceptional directivity. The vertical plane dispersion reduces the
comb-filter effect of early reflections off the console surface, while the
broad horizontal dispersion affords engineers greater freedom of movement.
Precisely tuned electronic crossovers offer high
amplifier output with minimal distortion. Protection circuitry allows
impulse peaks through and responds with limiting only when a voice coil is
in danger of thermal overload or a power amplifier runs the risk of
overheating.
The O 300 D includes very flexible room-matching circuitry to alter the
amplitude response of the monitor as needed, depending on speaker placement,
in multiple steps and in three critically relevant frequency ranges. A
special connector provides direct access to each of the three power
amplifiers and allows the use of the external K+H Pro C 28 digital
controller. The O 300 D is additionally equipped with switchable inputs for
transformer balanced analog as well as digital signals in both AES/EBU and
S/PDIF formats that accommodate sampling rates up to 96kHz at 24-bit
resolution.
All three drivers are magnetically shielded to prevent interference with
video monitors or computers. The cabinet is available in either a
charcoal-gray enamel finish or a rugged dark-gray nylon-fiber nap with an
attractive metal grille, and offers a variety of mounting options.
Maximum SPL is 112.8dB (in half-space, 3% THD @ 1m) with a frequency
response of 40Hz - 20kHz (+/- 2dB). The bass, mid-range and treble
amplifiers respectively deliver 150 watts RMS (250W peak), 65W RMS (75W
peak) and 65W RMS (110W peak). Dimensions (W x H x D) are 15" x 10" x 11"
(12-inch with grille).
Klein + Hummel products are distributed exclusively in the United States,
Mexico, Central and South America and the Caribbean by Sennheiser Electronic
Corporation (www.sennheiserusa.com).
