Crown IT8000 8000-Watt Power Amplifier

The latest technology backed with the Crown name and quality!

The world has seen many good amplifiers, but few achieve greatness. What sets these elite few apart from all the others? The answer is simple: A careful synthesis of unrivaled sonic performance combined with rock-solid dependability.

While the definition of a great amplifier may be simple, delivering on those requirements is not. This is what has always set Crown amplifiers apart from the others: Crown delivers.

From the slightest nuances in the tremolo of a flute to the chest pounding bass of a rock ’n’ roll kick drum to the harmonically rich vocals of a jazz singer, Crown delivers. Crown amplifiers are renowned for their ability to accurately amplify anything audio—with unmatched power and accuracy—night after night without fail.

For decades, the formula for creating great amplifiers has been the same at Crown: An insightful combination of genetics, breakthrough technologies, craftsmanship, and passion. This formula, proven over and over, has produced a lineage of great amplifiers, each great in its time, and each raising the standard for high performance. Once again, this formula for greatness has delivered on its promise: I-Tech, the world's next great amplifier, and the pinnacle of Crown's 50-year history of innovation.
