CPX™ Series Power Amplifiers: Three rugged, ultra-affordable power designs in the great Crest Audio tradition.
In typical Crest Audio fashion, we’ve over-built and over-engineered the CPX Series. Especially considering their highly competitive prices.
We included built-in subwoofer crossovers, low-cut filters to prevent woofer cone flutter, fan cooling, Speakon® output connectors and much, much more.

Gain Comparator Limiting.
When a signal has waveform peaks that exceed the amps’ power-supply rails, waveforms get chopped off, or “clipped.” This undesirable distortion most often happens when the amp is turned up too high (too much gain). GCL™ senses clipping (or current limiting) and dynamically reduces the gain for a few milliseconds. You can drive the CPX amp to its maximum (and beyond) without hearing audible distortion.

Don’t settle for less.
If you need maximum performance on a tight budget, you owe it to yourself to get your hands on a CPX Series amplifier from Crest Performance.
