    Help Identifying speakers

    Hi all.
    These speakere are from a 1965-67 Ampeg Portaflex.
    Its a Jensen but I cant find any more information on the exact model name or wattage rating, ceramic ot alnico ect:
    Anybody here good with ID'ing speakers.
    The date code is 220652
    Thanks.

    Those would be Jensens made in the 52nd week of 1966.
    Date code breaks down as follows:

    220 = manufacturer code
    6 = year (since your amp is 65-67, the assumption is 1966)
    52 = week

    Here's a link for future reference; especially check out the bottom of that page that goes into great detail on Jensen speaker codes. Yours are out of the ordinary.

    Thanks Ric, I knew the date, was wondering if anybody knew the model. IE: C12N ect:

    Perhaps its just called Concert series as it says on the bell but I havent heard much about this name which seems kind of odd.

    The model is EM1202. What it means is a mystery. The EM is the type of magnet, the 12 is the size, the 02 is the speaker "quality".
