Refresh yourself with internal and external maintenance! JBL's 4311A was developed as a monitor speaker for studios, etc. I would definitely recommend this system to customers who listen to jazz and rock because of its good overall tightness and smooth low range. The exterior is generally clean due to maintenance, but there are repair marks left on the tweeter and scoker, serial 30617 29153 (Asaine Tomo)
