Crest Audio Announces LH Series Loudspeakers January 23, 2001Crest Audio announces the introduction of its LH Series loudspeakers,
a full range of sound reinforcement speakers able to produce extremely high SPLs,
with a wide dynamic range to meet the needs of today's touring and fixed installation
professionals. The LH Series, the result of a comprehensive R & D effort by
Crest Audio, offers a variety of loudspeaker solutions for clubs and fixed installations,
as well as regional touring rigs and DJ applications.
Designed to provide professional sound quality, extended frequency response
and extensive power-handling capabilities, the LH Series is comprised of seven
models: four trapezoidal-shaped enclosures (the LH1, LH2, LH3, and LH4 subwoofer),
and three floor monitors (the LH5m, LH6m and LH7m).
The trapezoidal cabinets allow arrays to be constructed more easily, while
greatly reducing the build-up of internal standing waves to ensure a minimum of
mid-bass and mid-range coloration. The LH1 is a two-way speaker system featuring
a 1 x 15" woofer and 2" titanium compression driver, with a frequency
response of 48Hz-20kHz and crossover frequency at 1600Hz. The LH2 is a three way
speaker with a 1 x 15" woofer, 1 x 15" woofer/mid-range, and 2"
titanium compression driver. Both woofers combine below 300Hz, while only one
produces signal above 300Hz. The LH2 has a frequency response of 55Hz-20kHz and
a crossover frequency of 300Hz low-mid/1700Hz mid-high. Also a three-way speaker,
the LH3 has a 1 x 15" woofer, 1 x 8" mid-range driver, and 2" titanium
compression driver, with a frequency response of 53Hz-20kHz and crossover frequencies
of 500Hz low-mid/3700Hz mid-high. The LH4 subwoofer contains two 18" woofers,
with a frequency response of 45Hz-300Hz.
Two floor monitors round out the LH Series loudspeakers: The LH5m employs
a 1 x 12" woofer, 1" titanium compression driver and has a frequency
response of 58Hz-18kHz. Crossover frequency is 2000Hz. The LH6m features a 1 x
15" woofer, a 2" titanium compression driver, and has a frequency response
of 59Hz-20kHz, with a crossover frequency at 1700Hz. The LH7m features 2 x 12"
woofers, a 2" titanium compression driver, and has a frequency response of
53Hz-18kHz, with a crossover frequency at 1700Hz.
Utilizing B&C® OEM transducers, LH Series speakers are equipped with
600 watt continuous-rated woofers along with 140 watt continuous-rated compression
drivers. These are further enhanced by internal crossover circuitry, which includes
an innovative mid-range contour switch (with HIGH and NORMAL settings) allowing
the user to choose between flat or slightly-attenuated mid-range frequencies to
easily adapt to a wide variety of sound reinforcement situations.
LH Series speakers may be driven in full-range or bi-amp mode by simply plugging
into the desired jack on the input plate. Crest Audio's protection circuit for
mid and high frequency drivers, a newly-designed feature that subtly decreases
signal level to the drivers and provides extra protection against damage from
long-term overpowering, is provided for both full-range and bi-amp modes. In addition,
connections via a heavy-gauge aluminum input plate include Speakon input
and thru jacks, as well as an exclusive four-pole switching Speakon connector
for bi-amp operation.
Crest's LH Series cabinets are constructed of high-quality 3/4" seven-ply
hardwood for rigidity and warp-resistance. Recessed steel handles with comfortable
round hand grips provide increased mobility, while a heavy-gauge metal grill with
black powder-coat finish gives an added degree of protection. For more information, visit their web site at www.crestaudio.com. |
