The 4500 can handle crowds of up to 1,000 people. It won over a lot of people with its dual-function allowing you to use it both as a full-range sound system or a PA system with clear voice and great projection, at the flip of a switch. It comes with an 8-inch woofer and a titanium-dome compression driver, as well as an integrated circuit amplifier. It features a sturdy and very durable injection-molded case. The Liberty MPB-4500 is battery-powered, offering up to 117 dB with a 50-watt power output. It uses lead-acid batteries at 12V and 2.6AH which offer 5-6 hours of play per charge.
