I have 3 P10R's from 1958/1959 with original cones in my 59 Bandmaster. They aren't blown (ohm out around 6 ohms). No cone rub. No tears, but they sound more fuzzy then I would expect. I have a 4th P10R 1959 that is a recone and it sounds tons better. I tried these in a couple different amps and they are pretty dirty at mid level volume (ie, medium to loud bedroom levels). I tried them at a gig at they just seemed to crap out trying to get loud enough to be heard over the drummer. I'm wondering if old speaker can go bad, but not be an obvious blown speaker. Also wondering, if you were in my shoes would get them reconed, or leave them as is for the next guy who might prefer original cones, even if they sound sub-par.
