DESCRIPTION

The Crest LQ 10P is a powered, bi-amplified, two-way speaker system engineered to provide the highest levels of performance and capable of over 120 dB peak SPLs.The enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal form with a coated, perforated metal grille to offer a cosmetically elegant yet durable powered speaker system.

This two-way powered system packs a 200 Watt dynamic peak power amplifier driving a 10" heavy-duty, long-throw woofer with a treated cone and dust cap for environmental stability.The HF-1 compression driver is driven by a 70 Watt peak dynamic power amplifier and features a 1.4" titanium diaphragm.The HF-1 is coupled with a patented Quadratic Throat Geometry constant directivity horn (US Patent #6059069) with a coverage pattern of 90˚ by 45˚ molded integrally into the enclosure.

The preamp/EQ’s balanced inputs include one combo female XLR, a 1/4" RTS phone jack and one male XLR, all connected in parallel.The power amplifiers providing the bi-amplification are low-distortion units providing 150 Watts RMS into the nominal 8 Ohm load of the woofer and 50 Watts RMS into the nominal 6 Ohm load of the tweeter.They were selected for their reliability and superb performance capability. Both amplifiers have clipping prevention compression, which virtually eliminates audible power amplifier clipping.

Molded-in handles provide ease of transport, while multiple mounting points (top and bottom), equipped for an Omnimount75 series and a molded-in stand adapter, provide for maximum utility.

Architectural and Engineering Specifications

The Crest LQ 10P has a frequency response from 80 Hz to 20 kHz.The peak SPL with inaudible distortion reaches 120 dB with music as a source when measured at a distance of 1 meter and driven to full output capacity. The system utilizes a 10" heavy-duty, long-throw woofer and a HF-1 compression driver tweeter.The nominal radiation pattern is 90˚ in the horizontal plane and 45˚ in the vertical plane.

The powered, biamplified loudspeaker system has a group of medium impedance input connectors consisting of one combo female XLR, a 1/4" RTS phone jack and one male XLR, all on the rear panel and connected in parallel. A Link Out and a Link In jack is provided, and level control is located next to the input jack group.

The system power, amplifiers have an unfiltered frequency response of

10 Hz to 30 kHz, which deviates no more than +0, -1 dB up to rated power; a damping factor greater than 100 @ 1 kHz into 4 Ohms; hum and noise better than 90 dB below rated power; and THD and IMD of less than 0.1%. The woofer amplifier is capable of 150 Watts into an 8 Ohm nominal load, and the tweeter amplifier is capable of 50 Watts output into a 6 Ohm load. Both incorporate independent clipping prevention compression.
