LINER NOTES

The history of some of the world's most famous and valued JBL loudspeakers traces back to the 1960s, commencing with the 4320 model. To enhance the dispersion of high frequencies, a smaller-diameter tweeter replaced the original one. Additionally, adjustments were made to the crossover frequencies to achieve a smoother response. This updated version was designated as the 4311 and featured a conventional recessed baffle, along with an H.F. radiator raised to the acoustic plane of the woofer and the front edge of the enclosure. JBL recommended it as "a compact package delivering smooth, powerful, and broadband response."
