Crest Audio Announces LH Series Loudspeakers

Crest 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.
