The Keiga KG-5230 is a plate Subwoofer Amplifier with Electronic Crossover intended for building powered subwoofer systems. This amp has an adjustable electronic crossover and possesses enough power to deliver excellent bass without added distortion. We are confident this amp will meet the demands of both home theater and high end audio systems. Powered subwoofers are a versatile addition to your audio system. With the variable crossover and volume control, you can match a subwoofer to any existing system. This amplifier can be used with single or multiple woofer systems (a total impedance of 4 to 8 ohms is recommended). The crossover can be turned off if you are using the amplifier with a system that already has a built in crossover.
As of 2007, Keiga Amplifiers will be warrantied for two years from date of purchase. The amp must be sent in for us to verify the serial number.
