As a quick follow up, and thanks for letting me jump on and steer this thread around a bit, I busted out the mono LPs and did some comparisons. That's where the differences appeared. The recapped speaker has a solid presence through all 3 drivers, with a noticeable boost to the squawker. The old speaker sounded grainy and 'RIAA curvy'- treble and bass but low mids. Decided to replace the caps in it and the Fortes have never sounded better (though I've only had them for a month)
