The best way for mobile audio to be heard is up in the air above the crowd on tripod stands. The American Audio SPS-1B is a great solution because it's a light weight (only 6 pounds) aluminum tripod stand with a pole mount to put your speakers on. It's easy to set-up and takedown. The included safety pin allows for maximum security. The SPS-1B can hold up to an 80 pound speaker.
