If you are in the market for serious portable speakers for a job site or a backyard party the Ion Audio has you covered. When I say serious, I mean industrial size and strength.
Bars not only protect the speaker, but also make for easy transport. The device batter powered and Ion Audio claims up to 50 hours of battery life. It has both wireless, Bluetooth and auxiliary inputs, the side acts as a power strip, AM-FM radio and is rugged enought to withstand a job site with sawdust, dirt and more.
The speaker weighs just over 20 pounds and pricing and availability have not yet been announced.
