Product Description

The Crest Audio CA 18 professional power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability – even when operating under extreme stress – in touring or fixed installation applications. The CA18 provides high power output coupled with true clarity and is well-suited for high-powered subwoofers and passive full-range systems.

Absolute sonic accuracy

Absolute sonic accuracy is the hallmark of every Crest amplifier.
Bass is solid and defined to the limits of audibility, with ample current reserves delivered by an “over-engineered” power supply and advanced Class H circuitry. Wide-bandwidth output devices assure a detailed, transparent high-frequency response. And, thanks to Crest’s exclusive IGM circuit, the CA18 will drive 2Ω loads safely without compromising performance.

Construction and Quality Control

The Crest Audio CA18 is built exclusively in Crest’s USA manufacturing facility, with internal components selected for

premium quality and proven durability. Each modular subassembly is pre-tested,

and once assembled, the CA18 receives a rigorous “hot room” burn-in before thorough final pre-shipment checkout on precision test equipment.
