Derived from the legendary JBL® model 4425 studio monitor – the brand’s first compression-driver system with a Bi-Radial® horn and a large-format woofer – the 4429 studio monitor incorporates a number of important improvements designed to give true studio performance in transportable size without requiring a subwoofer. An ultrahigh-frequency transducer, an improved high-frequency compression driver and horn design, a new crossover network and improved internal bracing combine to give the 4429 an advantage over previous models in the naturalness, clarity and detail of its sound. Featuring a massive, 12-inch (300-millimeter) woofer and large compression drivers mounted in 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 live performances – all while delivering up to 200 watts when powered by a separate amplifier. Effortlessly delivering the full bandwidth and dynamics of the newest digital media – yet without suppression at any listening level – the 4429 reveals subtleties that you may never before have experienced in recorded music. JBL engineers have directed every detail of the loudspeaker’s design and construction toward a single goal: uncompromised sonic performance.



  • Extremely rigid, heavily braced enclosures of 25mm (1-inch) MDF
  • Dual front-mounted ports provide optimal woofer tuning for extended bass response and permit speaker to be placed against a wall
  • Continuously variable MF and HF attenuators let users tailor driver output to suit room acoustics or personal preference
  • Bi-wire capability for use with multiple amplifiers and speaker-wire sets
  • Walnut veneer with polyurethane topcoat and blue baffle and grille continue the classic JBL studio-monitor look
