How to Date Jbl Speakers

The D departed from common loudspeaker design in a number of important ways. First, the frame was cast, instead of stamped, for increased durability. It was one of the first loudspeakers to use Alnico magnets, making the D highly efficient and capable of higher output. The 4-inch diameter voice coil was much larger than other models and edge-wound with rectangular ribbon wire, which provided superior performance. D also featured a very shallow curvilinear cone and 4-inch center dome for extended high-frequency response. All of these innovations resulted in a loudspeaker that was 10 dB louder than typical speakers and capable of handling significantly more power. D quickly became the standard for a number of applications, including early s hi-fi systems. Guitarists began to swap out their stock Fender speakers for JBL Ds to achieve louder, cleaner tones.
