The JBL 4315 is a compact 4-way speaker system designed for studio monitoring, part of JBL's professional monitor lineup. It features a robust construction with a total weight of around 100 pounds, making it substantial and durable. The speaker configuration includes a 30 cm cone woofer (model 2203A) for deep bass responses, a 20 cm cone woofer (model 2108) for mid-bass and lower midrange, a 13 cm cone speaker (model 2105) for midrange and high frequencies, and a horn-type tweeter (model 2405) for the high-frequency range. This speaker utilizes a bass reflex enclosure design, enhancing low-end performance and efficiency. The back of the enclosure is fitted with metal support fittings, allowing for suspension if needed. Two finish variations exist: the 4315A, featuring a gray finish with a black grille, and the 4315AWX, which showcases a walnut finish with a blue grille and baffle. These speakers are highly regarded for their sonic accuracy and clarity, delivering a live music experience that is difficult to match in other speaker systems. The craftsmanship includes high grain furniture-grade walnut, contributing to both aesthetic appeal and sound quality. JBL 4315 speakers are particularly sought after by collectors and audiophiles for their impressive performance and visual design.
