    Hello everyone,

    I have a 10" speaker that I'm trying to identify. I was told that it's the original Fender speaker from a 1967 Princeton Reverb that was reconed in the 1970s. However, I've been unable to find photos of a Princeton with a similar looking speaker. There's no Fender sticker on the back. Instead, there is a sticker for "Super Music Products". I think that leaves two possibilities:
    1. The most likely explanation is that it's not a Fender speaker. It's an old speaker from a now defunct company called Super Music Products.
    2. It's a Fender speaker reconed by Super Music Products, who replaced the label with their own sticker.
    Does this resemble any original Princeton speakers that you've seen?

    Not a SF Princeton speaker. The Square mag and the paper gasket on the BACK of the rim indicate it may have been an old PA speaker that was front mounted and maybe reconed. Is it actually 8 ohm? Many of those were 16 ohm or etc.The label is likely the reconer's.
    Likely a Utah or CTS PA speaker frame.

    Thanks for the responses so far. I can't see any code numbers on the speaker basket, unfortunately.
    The observation about the paper gasket on the back of the rim is interesting. There is also an [thicker] paper gasket on the front, but perhaps it was designed to support both mounting options. There are some adhesive globs on the back paper gasket [visible in the photo] but these could be from handling the speaker with sticky fingers during the reconing.

    The resistive impedance measures 6.4 ohms, so it's in the 8 ohm ballpark.

    Basket looks cts. Mag is ceramic though.
    Usually their ceramics were round but maybe outlier

    Judiciously use some mineral spirits to release that paper gasket from the back of the speaker basket's rim. The manufacturer's code will be stamped on the rim.

    If you just pull the paper off, you may pull paint (and the code) with it.

    Thanks schmee, I think that picture confirms that it's a CTS. I haven't actually played through it yet but I'll try it later tonight. I'll also try to carefully remove the paper on the basket rim and report back.

    Yup - CTS. I have a '68 PR in very nice condition that I got used about 15 years ago. It came with the same square ceramic magnet speaker (but with the Fender donut sticker), and although the date codes jibed, I was always a bit skeptical of its originality. Maybe not anymore...but the gasket has me wondering a little.

    I managed to scrape off most of the SMP sticker, which revealed the following stamped info:

    PA 10
    MEXICO
    137 7813

    The 137 confirms it's a CTS and is probably a PA speaker like schmee suggested. The 7813 indicates that it was manufactured in the 13th week of 1978, right?
