Just read an ad on ebay and would like to get the opinion of some of the forum members on the sellers comments. The as is for a set of L100's and while I am not trying to get the debate on the L100's going again I would like to understand the accuracy of the comments. The seller states that the speakers are 2nd generation (1973-75) version of the L100 and are "considered best of breed by most knowledgable JBL enthusiasts because of the inclusion of evolutionary improvements like a functional bass port and the use of heavy-duty Alinico magnets on both the LE 5-2 midrange and the D123A woofer, but produced before Harmon International induced cost-cutting changes (elimination of Alinico magents, etc- post 1975)". Were speakers produced after 1975 inferior
