Compact & Ultra High Powered LF System

The HPI18BP Bandpass 18" Subwoofer - how to get the most power and output from the smallest size.

The AES 1,000W – Peak 4,000W single 18 bandpass subwoofer is a high output and relatively compact solution for extended range bass over long durations. The HPI18BP is suited as a stand-alone unit or as part of a high powered large venue system. 

The combination of high tech hand built Australian made driver and bandpass design means high efficiency, and very high output. The HPI18BP is ideally suited to electronic dance music in medium to large venues over long duty cycle durations.
