The L300 has been refreshed both inside and outside. It has a good sense of balance in the range, and the total balance is wonderful, so it doesn't make you feel old-fashioned at all. It has a reputation as a model with a particularly high degree of perfection among JBL from the 70s. Not to mention the thick mid-low frequencies typical of JBL, the sound loss of the 077 tweeter is excellent. The exterior has scratches on the glass plate. Serial 23219A, 23419A (Kimiya Miura)
