The 800lb gorilla of the TOGO series, the Gemini AS-15TOGO features a 500W (2,000W peak) Class AB high-efficiency amplifier pushing a 15" high-excursion woofer, and powerful 1.5" high-frequency compression driver. It has no problem filling any sized room with stunning, wall-shaking sound. But all that power is no fun if you can’t put it where you want it, so a long-lasting internal Lithium Ion battery is included, turning the AS-15TOGO into your own portable BOOM factory.Plenty of Brains to Matc..
