EXCELLENT JBL 4311 STUDIO MONITORS SPEAKERS – ICONIC VINTAGE VOICE – LEGENDARY WEST COAST SOUND

 Condition: Excellent – Clean drivers, matched pair, tested and sonically balanced

The JBL 4311 is one of the most iconic studio monitor designs in history — the direct descendant of the legendary JBL 4310, used in countless professional recording studios during the golden age of analog. Built for precision monitoring, the 4311 delivers a forward, punchy, and dynamic sound signature that remains thrilling decades later.

With its 12″ woofer, LE5-2 midrange, and LE25 tweeter, the 4311 provides fast transient response and bold clarity across the frequency spectrum. Its signature design places the tweeter and midrange below the woofer for optimal time alignment when used in horizontal orientation — just like the pros did. These monitors are not just functional; they’re a piece of recording history, with heavy-duty cabinetry and a no-nonsense industrial aesthetic.
