The Kick15 represents a new and more powerful amplifier design for keyboardists, drummers, and those needing a personal PA. You get 400 Watts of peak power in a true bi-amped design with a custom-tuned electronic crossover, an integrated four-channel mixer and built-in Alesis effects. Just like Alto Professional"s industry-leading Truesonic loudspeakers, the Kick15 is a fine-tuned performance-hungry machine. Each component has been optimized for maximum efficiency, giving you an amplifier that sounds amazing, is lightweight, and has everything you need without the filler.
