JBL D2430H Compression Driver (#5061586X) D2 Dual Diaphragm 3" Diameter.
The revolutionary D2 Dual Driver dramatically improves the sound and performance of high frequencies, providing an extreme output advantage over conventional systems with significantly higher array power, reduced distortion, double the number of voice coils and more than double the power handling. This results in a dramatic increase in pure high frequency sound pressure levels in the same physical footprint with a 30% reduction in weight.
A revolutionary device that merges two compression drivers into a single compact transducer, establishing a new benchmark for pure high frequency output and low distortion. Dual Diaphragms Provide Increased Radiating Area for Higher Output.
The main idea behind this new type of
high-frequency driver is to marry two drivers back to back with a special radial phase
plug that feeds their energy towards the
center so that it can exit together in one direction. The two back-to-back diaphragms
operate in “push-push” mode, each with
their own back-to-back phase plug between them. Each phase plug has its own
radial channels to direct their energy towards the central opening and then out the
driver’s exit together, in one direction.
