Known as “Caleb,” the J5-4015 is simply the most accurate and powerful High Q loudspeaker ever created. A single cabinet can produce quality audio well beyond 1,000 feet from a true full range Synergy Horn™ housing (12) 18-inch drivers, (32) 8-inch mid-range drivers and (64) 1-inch-high frequency compression drivers. And yet even with all that power, we do not sacrifice one iota of clarity and quality.
