Product Description

JBL 4349 Studio Monitor is a compact, high-performance loudspeaker built around the patented D2415K dual-1.5" compression driver mated to a large format horn, paired with a 12" cast-frame Pure-pulp cone woofer. This combination delivers music with authority and accuracy not possible from traditional loudspeaker designs.

Acoustic Technology

Built in JBL’s world-famous acoustic engineering facility in California, the 4349 Studio Monitor showcases patented JBL acoustic technologies. This monitor loudspeaker features a 2-way design with High-Definition Imaging (HDI) horn technology, the D2415K dual 1.5" (38mm) compression driver as well as 12" pure-pulp cone woofer for powerful dynamics and incredibly accurate sound reproduction.

High Definition Imaging

JBL’s revolutionary High-Definition Imaging horn geometry is the result of intense research into the nuances of horn design. In search of exceptional high-frequency detail and uniform directivity for smooth in-room response, JBL engineers pioneered a design that delivers neutral frequency response both on- and off-axis and provides a seamless transition between the high and low frequency drivers.

Compression Driver

The JBL D2415K compression driver benefits from the advanced research and applications derived from JBL Professional’s “D2” range of transducers. At the core of the D2415K device is a pair of lightweight, polymer, annular diaphragms that improve high-frequency extension by reducing diaphragm mass. The V-shaped geometry of the annular diaphragm reduces breakup modes, eliminating time smear and reducing distortion. The result is incredible dynamics with accurate reproduction and a lack of power compression. The “D” prefix indicates that this driver utilizes dual diaphragms, dual voice coils, and dual motors for an incredibly efficient design.

Tonal Adjustment

High-frequency and Ultra High-frequency tonal adjusters allow the sound to be tailored to the specific environment and listener preference. The controls work together with an advanced crossover network design that features air-core inductors, cast wire-wound resistors and low-ESR metallised film capacitors in a multi-cap configuration to optimise the performance of 4349 drivers. The multi-cap technique improves series capacitance by averaging their values while lowering ESR and distortion.

Driver Array

The 4349’s powerful 12" (300mm) woofer takes advantage of core JBL engineering techniques to ensure very high output with low distortion. The 3" (75mm) long-throw voice coil in conjunction with dual opposing spider dampers guarantee maximum output with significantly reduced distortion. A Pure-pulp cone provides a lightweight, rigid diaphragm and helps to eliminate breakup modes ensuring proper pistonic motion throughout the operating band.

The 4349 enclosure is heavily braced with 1-inch (25mm) thick walls to provide a solid acoustic foundation and incorporates a bass reflex design with dual front-firing, computer-optimized flared ports. The cabinet features a classic JBL studio monitor design with a blue baffle and is finished in a choice of Walnut or Black Walnut furniture-grade satin wood veneers. A blue (Walnut) or black (Black Walnut) cloth grille completes the elegant appearance. Dual sets of gold-plated binding posts provide a secure connection and offer a choice of single-ended or bi-wire/bi-amplified connections.
