Upland Loudspeaker Service...JBL Authorized Since 1988
JBL Recone & Added Service Prices with Reproduction Kits
Vintage JBL loudspeakers from the 1950s through the late 1970s with AlNiCo magnets will lose some of their magnetic energy over the decades. Typically, the energy in the magnetic gap will be down approximately 10-20% resulting in a diminished performance of the efficiency, sensitivity and frequency response of each driver. To make sure the loudspeakers are performing at their peak capability and reliability, it is highly recommended to disassemble, clean and recharge each AlNiCo motor structure. This will ensure "like new" performance. Later loudspeaker models with ferrite (ceramic) magnet motor assemblies do not require a recharge. However, ferrite motors with a shifted magnet/pole piece can be realigned provided the magnet itself is not destroyed.
Motor/Magnet dissassembly, cleaning and recharge, add $85.00
