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 with good overall sound tightness and good low frequencies. Some of the lettering on the exterior has disappeared, but it is generally clean.
