Models KSN 1140A Horn Drivers
The POWERLINE series of speakers developed by Motorola/CTS incorporate protection circuitry which allows them to be used safely with amplifiers rated as high as 400 W. This results in a product that is practically blowout proof.
The KSN1140A speakers were designed to provide a smooth response over the 2 kHz to 20 kHz range. Similar products with the Model KSN1142A.
