About the 4312G
The JBL 4312G is a classic-format, passive three-way studio monitor loudspeaker descended from JBL’s 4310/4312 monitor lineage. It uses a large 12-inch pure-pulp woofer, a polymer-coated 5-inch pure-pulp midrange driver, and a 1-inch magnesium/aluminum alloy dome tweeter with an acoustic-lens waveguide. The front-firing bass-reflex enclosure is designed for placement on sturdy stands, shelves, or consoles, while front-panel midrange and high-frequency attenuators allow tonal adjustment. The 4312G is sold as a mirror-imaged matched pair and is suitable for use with a broad range of amplifiers capable of 10–200 watts RMS per channel.
