The MAX-Wall 420 portable acoustic treatment system is the perfect solution if you're in a rented space and don't want to, or aren't allowed to, mount anything on your walls. They're also good if your place needs to serve a variety of acoustical purposes, or if you're on a budget and have acoustical problems that can't wait. If you're the sort who likes to mix things up on the fly, the MAX-Wall system will keep pace with your busy schedule. So, go ahead, turn any room into a temporary performance or mixing space. This is the purple version.
