L19 = 4301 except JBL Blue
i bought my 4301B pair new in 1982 in Paris, reconed one time by JBL (due to over X damage :blink: on 116H following by VC failure ...), and they are now as new in their original JBL boxes, well protected against UV ... I never forget to rotate each cabinet by 180° each six months. Sometimes i open the boxes just to see and smell them. They are the smallest great sounding speakers that i have heard. In near field hearing conditions you can imagine separately each acoustical instrument.
Very impressive speakers :p
