The PowerBass PBX Series Amplifiers are the cleanest most efficent amplifiers we have built to date, with attention to sonic accurracy, clarity, and a bold use of efficient power, this series is guaranteed to have smiling with pure musical enjoyment. PBX Ultra High Efficiency Amplifiers are the result of extensive engineering and testing to develop the best sounding and most efficient power delivery we have ever produced. With the success of our previous XMA series our engineers went to work on the PBX Series with the goal of creating true works of art featuring high quality parts and an ultra efficient circuit design proving to be some of the best Class D amplifiers on the market today. The PBX Series represents the very latest in Class D Technology. IR, a leader in PWM circuit design, has worked in conjuction with PowerBass engineers to produce more stable power output, minimal RF interference and improved sound quality. Available in Full-Range Digital 4CH, 6CH, and 5CH models as well as D-Class Mono Blocks from 800W to an astounding 3000W RMS the PBX Series has the power and channel configurations to meet the demands of the most demanding setups.
