Coastal Source has completed development of a custom-built outdoor amplifier lineup in partnership with Powersoft. The new models are engineered for durability, advanced power management and AES67 network integration, and are now shipping.

The collaboration brings together Powersoft’s amplifier engineering and Coastal Source’s expertise in outdoor audio. The result is eight purpose-built amplifier models designed for residential and commercial installations in harsh outdoor conditions.

The company says the new amplifiers are engineered for efficiency, durability and advanced power management — qualities aligned with Coastal Source’s standards for outdoor installations where moisture, salt air and temperature extremes are common.

The new line expands Coastal Source’s premium audio portfolio and is built to perform in environments with exposure to water, salt, and extreme temperatures.
