Portable speakers can be very nice little accessories to carry around, but the “little” part often extends to the sound as well. Forum member Dobson did his own thing and instead put speakers in a backpack.
Dubbed the “sound bag” by its creator, this thing is quite impressive with 2 large speakers powered by a 50W amplifier that runs off a 7000mAh battery, which gives the rig a battery life of about 15-20 hours. This will definitely play louder than anything even an army of normal portable speakers can spit out and might not be too bus-friendly, but it definitely has style. Great work!
