500 Watt Class-bd Mono Amplifier P500-1bd

500 Watt Class-bd Mono Amplifier P500-1bd

The Punch P500-1bd is a mono amplifier capable of 500 Watts into a 1-Ohm load. The Class-BD technology produces bass more efficiently over traditional amps, and its frequency response allows it to be optimized for subwoofers.

Overview

With its super efficient Class-BD circuit topology, the P500-1bd will drop some serious BASS! Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. No need to worry because its 1-ohm capability will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease.
