JBL studio monitors pair new tech with classic design

JBL coupled its D2415K dual 1.5-in driver with its large format HDI horn to release the JBL 4349 studio monitor.

The monitor features a 12-in cast-frame and Pure-pulp woofer cone. It was designed and engineered in Northridge, California. 

The JBL D2415K compression driver features a pair of lightweight, polymer, annular diaphragms that improve high-frequency extension by reducing diaphragm mass. V-shaped geometry of the annular diaphragm reduces breakup modes, eliminates time smear and reduces distortion resulting in incredible dynamics with accurate reproduction and a lack of power compression. 

A 12-in woofer on the new JBL 4349 studio monitor is designed to ensure very high output with low distortion. The 3-in long-throw voice coil in conjunction with dual opposing spider dampers deliver maximum output with 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.

High-frequency and ultra high-frequency attenuator controls allow sound to be tailored to the specific environment and listener preference. These controls manage an advanced crossover network design that features air-core inductors, cast wire-wound resistors and low-ESR metallized film capacitors in a multi-cap configuration.  

The new monitor is designed with a blue baffle and a choice of Walnut or Black Walnut satin wood veneers and a blue (Walnut) or black (Black Walnut) cloth grille. Dual sets of gold-plated binding posts provide a secure connection and offer a choice of single-ended or bi-wire/bi-amplified connections. The enclosure has 25mm thick walls. JBL says JS-120 floor stands can be paired with the monitors.
