The new XT series amplifiers deliver POWER on a whole new level. With years of research and development, and extensive field testing, improvements were made in both performance and reliability. In addition, we also added some cool new features, starting with an enlarged engraved logo on the heatsink, large 4 awg speaker terminals for reduced resistance, and clipping indicators on both the amplifier and bass control knob to monitor the INSANE POWER that these amplifiers can produce. The PCB design was improved from top to bottom to create power more efficiently and allowing us on certain models to shorten the overall footprint for those who are limited on space. One feature that did not change was the use of XS POWER Flex Series power cable on our PCB layout. This 100% pure OFC wire allows for the best current transfer across the PCB for increased efficiency.

All XT series amplifiers were designed to work with todays electrical options, as technology has changed over the years with amplifiers, so has the electrical options to supply these mega power systems. XT series amplifiers were designed to produce rated power at 12.5 volts and will keep increasing power up to their max voltage of 16 volts. It does not matter if you are dedicated SPL competitor or a guy who just wants to listen to their system at ridiculously loud levels, these XT amplifiers will deliver the power you need and much more!
