LQ™-P Series and LQ™ Series

Does the world need another plastic powered speaker? It does when Crest-quality power amplifiers complete with our CGL™ technology are inside. It does when you hear how good these three active speaker models sound.

Sometimes less is more.
Crest LQ-P Series active speakers let you reduce the size of a mobile system to its bare essentials without compromising sonic quality. Consider the system diagram shown at right. It’s a complete 24-input, stereo PA rig in just three components.

That’s because the power amplifiers, electronic crossovers and a lot of other electronics are built right in to the LQ-P speakers. Of course, we suggest adding a CPS-1203 Spectrum Enhancement System and probably a CPL-1288 Compressor/Limiter/Expander for lead and back-up vocal channels... but you get the point. LQ active speakers take a lot of the load out of load-in.

Packed with Crest technology.
Each LQ-P active speaker contains two power amplifiers specially designed for their transducers as well as built-in phase accurate electronic crossover, time compensation, parametric equalization and protection circuitry.

Cooled by massive rear-panel heat exchangers, these amps are connected to professional-grade woofers with oversize voice coils and to our highly-regarded HF™ titanium-diaphragm compression drivers with ferrofluid voice coil cooling.

The 2-inch HF used in the LQ-15P/LQ-15 employs our patented Radialinear Planar Phase Correction System that extends and smoothes frequency response.

Midrange/treble output from the driver is channeled through our patented Quadratic Throat Horn™ design which provides ultra-low distortion coupled with well-controlled dispersion pattern and lower distortion than many other CD horn geometries.

Loaded with extras.
Besides signal pass-through connections for daisy-chaining speakers, LQ-P models have an additional output that’s placed after the rear-panel level control knob. This lets you control volume for multiple LQ-Ps from the first speaker’s level knob. There’s also a direct-to-amp input that lets you bypass internal crossover circuity, for running the speaker as part of a multi-way system.

The LQ-15P even includes its own mic preamp for the ultimate lean, mean public address system (one microphone, one LQ-P and they’ll hear you in the next county).

All molded enclosures are not created equal.
It takes an incredible monetary investment to do an injection-molded speaker right. It has to be shaped trapezoidally to capture and suppress internal resonances. And it requires complex internal bracing built right into the mold to minimize external resonance. Crest spent the money. Many others have not. We think that you will hear the difference when you audition any of the LQ active or passive models at your Crest Performance dealer.

And if you already have your own amplifiers we offer the same ten-, twelve- and fifteen-inch LQ Series models without internal amplification. Each uses the same high-quality transducers, Quadratic Throat Horn™ and includes EQ contour control, Dynamic Protection System and bi-amping capability.

Either way you go, your audience will hear the Crest Performance difference.
