JBL loudspeakers have been a top choice of music lovers and audiophiles for more than 70 years. Embodying that legacy, the 4307 10-inch, 3-way Studio Monitor is designed and engineered to bring studio-quality sound into your home. Featuring a 10-inch pure-pulp cone woofer for natural, undistorted bass, a 5-inch polymer-coated midrange speaker for pristine and dynamic human voice reproduction, and a 1 ½-inch tweeter with laminated tangential ring diaphragm for sparkling high frequency response, the 4307 fills your room with legendary JBL sound. The speaker’s compact form factor and sophisticated walnut veneer finish means it integrates subtly and elegantly into any décor.
