Sterling Audio MX3 3" Powered Studio Monitor/Speaker for guitar input

This is one speaker of a set. I don’t need this speaker & honestly unsure if it works solo. I think it does. For guitar plug in or other studio audio. the Sterling MX3 Black Powered Studio Monitors are the perfect solution. They sound great, have a stylish matte black finish, 3” LF drivers, 3/4” tweeters, front access volume control with dual 3.5 mm outputs and RCA connectivity. The monitor is perfect for home studios that need quality sound in a limited space.
