Dear Friends. hope all is well...
I have a nice Vintage pair of JBL L220 speaker systems. The LE14H's were re-foamed as were the passive radiators. Resistance is 6.1/3 to 6.6 respectively for the LE14H's. One System has slightly more bass and is clearer sounding. I believe it's a problem with the voice coil and not the re-foaming or where they rest. I'm considering replacing the LE14H with the LE14A.
Are these compatible as in.. could I use one LE14H in one system and a LE14A in the other system without compromising sound quality/differences? I see in the Schematic JBL diagrams that if the LE14A non serviceable the LE14H is acceptable replacement. Other than magnet materials what are the differences in the LE14A/LE14H/LE14H-1 or any other variations of the LE14 series? Any other suggestions would be welcomed in order to get these system to meet or exceed there design specs. I'm also aware that all the components in the crossovers are suspect to change in value over time that could affect the sound and that their tolerances are different ±10-20%. As far as re-coning these with JBL re cone kits C8RLE14A at this time this is not financially feasible. Does anyone out there have replacements that are priced reasonably. I need some help sorting this out. Thank you in advance for your care, cooperation and attention to this important sensitive matter. Sincerely, Raffaele
