History
the JBL Model 4429 Studio Monitor speakers look a great deal like many of the loudspeakers made in the 1970s.
The JBL 4429 studio monitor, introduced in 1970, was the company?s first bookshelf compression driver system with a Bi-Radial horn and large-format woofer, designed to give true studio performance in transportable size without the need for subwoofer augmentation.

The new JBL 4429 incorporates a number of important improvements over the 4425 and its successors. A UHF transducer, an improved HF compression driver and horn design, a new crossover network and improved internal bracing combine to give the 4429 an advantage in the naturalness, clarity and detail of its sound relative to previous models.

Effortlessly delivering the full bandwidth and dynamics of the newest digital media ? without suppression at any listening level ? the 4429 reveals subtleties you may never before have experienced in recorded music. Every detail of the design and construction of this system has been directed toward a single goal: uncompromised sonic performance.

Featuring a massive, 300mm (12-inch) woofer, and large HF and UHF compression drivers with a one-piece SonoGlass horn, the 4429 delivers quick, tight bass, a natural, well-focused midrange and clear, distinct highs to create listening experiences with all the richness and detail of the original performances.
