I wonder if anybody's got *reliable* specs for JBL262 series (not 2262) as used in the PRX512. Parameters as stated in JBL's latest TS PDF seem quite dubious to me, as Xmax varies vastly between different voice coil options (2.5 to 16mm, I can't believe that)

We're running some 4825 clones; while still quite satisfied with their performance, we're looking into replacing the woofers for some weight reduction. Alternatives are 2262H and maybe 262H (-1? What does -1 mean?).
