Echo – Built to Be Heard.
Turn it up and let it rip. Echo is the mid-size portable Bluetooth speaker system designed for those who want more power, more clarity, and a sound that refuses to blend into the background. Big performance without the full-size bulk — this box was built to make some noise.
Featuring a 2-speaker component setup, Echo combines a PRV 8" mid-bass speaker with a PRV titanium super tweeter to deliver hard-hitting bass, crisp highs, and a sound experience you can feel. Powered by a 160W x2 Bluetooth amplifier, Echo brings serious output in a rugged, portable package.
Power it your way. Echo is compatible with a pair of your favorite 18–20V tool batteries (not included), or upgrade to our 36V lithium-ion rechargeable battery option for a setup that’s ready whenever you are. Depending on your battery choice, Echo delivers up to 30 hours of playtime, keeping the music going from the first song to the last.
Whether you’re in the garage, at camp, tailgating, working, or just showing up with the loudest box around — Echo brings the energy.
Portable Power. Serious Sound. Built by BS Customs.
Every box is backed by our 1-year warranty covering part malfunctions, because we believe in standing behind what we build. Warranty covers manufacturer defects and component failures. Damage caused by misuse, modifications, accidents, or excessive abuse is not covered.
