Brush up with internal and external maintenance! JBL's 4311A was developed as a monitor speaker for studios, etc. It is a system that I would definitely recommend to customers who listen to jazz/rock due to the good overall tightness of the sound and the low frequencies with good omission. The exterior is generally good.
