Grateful Dead "Wall of Sound" using JBL D130's The cone is therefore less prone to breakup. Finally, the large diameter coil yields a stronger moving structure since the force applied to the coil is transferred to the cone over a larger area. The result is maximum utilization of the energy from the magnetic structure and maximum efficiency. This allowed the coil to use a single layer of wire that could fit in a narrower gap. The large coil also places more wire in the gap for fewer turns. The large coil dissipates heat more efficiently, increasing power handling and reducing dynamic compression. The advantages of this innovation are many. It was years before competitors were able to match this feat. The degree of precision necessary to maintain such a large, exact circular shape for both the coil and the gap was unheard of at the time. To achieve the maximum motor strength, the coil gap was designed to be a very narrow 0.05".
#JBL SERIAL NUMBER LOOKUP DRIVER#
It was the first low frequency driver to incorporate a coil of this large diameter. The 4" flat wire coil was the single most innovative feature of this design. It resulted in a driver with outstanding sensitivity, range and dynamic response. The coil was immersed in one of the strongest permanent magnetic fields yet developed for a loudspeaker. It incorporated a 4" flat wire voice coil attached to a light, curvilinear cone with a 4" aluminum diaphragm instead of a standard dust cap to extend high frequency response. It was personally designed and developed by James Lansing. The D130 was the second low frequency loudspeaker introduced by James B. This driver was responsible for establishing the nascent James B Lansing Sound as a force to be reckoned with in the loudspeaker industry. This wide range 15" driver was introduced in 1948 and remains in production to this day as the updated E130.
