    Hey Folks..

    Couple of pics of the codes and labels from an old Oxford/Fender 10 inch..i believe this was stock to my 1970 Princeton Reverb..shelved it, but now thinking about having it reconed with tighter bass in min. Hoping to identify specific model and version of model..some of these extra numbers throw me..plus, the label has some fade. Looks to be a 10J4-(?) 5?

    Yep, agree. 10J4-5 would be period correct.

    King,,.,
    Any idea what the 5 means?.--the dashed number on these Oxford speaker models..

    Also seems to be several 10'J'x designations..
    10J4, 10J5, i think a 10J6, too? what is going on here?

    ThNx...

    The letter is the power handling code. The number following it is seemingly an unknown code. Could it be a voicing code?? I don’t know, and I find no info on that dash number rolling. The 10J4 is the proper speaker for the Princeton, and your date code fits your amp....42nd week of 1969. I would think your amp is from early 1970?

    Yes. I suspect the -5 is a series number. I’ve seen earlier ones that were -4, and a late 70s -6...

    thanks guys..When I bought this PR there were a lot of things i liked about this speaker..very sweet highs, smooth through the mids...bass was fine until volume got up there..
    Thinking about doing a recone..but not sure it'll solve that bass issue when pushing it..

    I recently had a pair of 1955 p10q's reconed (smooth cone--paper was disintegrating)..decided to jump into a ribbed cone on these..They turned out amazing..not even broken in and sounding great..they stay very tight into driving the amp..thrilled with the result

    Wondering if this could be accomplished on these 10J4's...
    they already have ribbing in the cone tho so im not sure how far i'd get in improving that aspect..

    If you tried it before the amp got new electrolytic caps, particularly the filter caps in the can, try it again now.
    It's amazing what fresh filter caps do for "Oxfarts".
