Can anyone identify this 10" speaker?

    This came out of a Peavey 410tx that also contained one Sheffield and one Pyle. Googling produces a couple references to it as an Eminence driver, but they we're old for sale posts that may have been wishful thinking. I'm casting around for an excuse to build something else with all the various drivers I have lying around, but I'd like to know what I have first. Hoping this isn't one of those proprietary drivers with unpublished specs, although I still have the 410 box and I suppose I could reverse engineer it. Thanks for any direction you can provide!

    Well it's definitely Eminence 100%. That's all I can tell you :)

    Indeed. It is an OEM driver with proprietary, unpublished specs.

    Judging by the size of the magnet it's probably entry level, no better than an Alpha 10, and might even be a guitar driver. I bet the only original driver in the cab was the Sheffield, and they're no prize either.

    Meh. Well, good to know. In that case I think they're destined for little vocal boxes with a piezo, I'll either port them with something I can amend or just make them sealed. I think I have lpads around here to put in line with the tweeter, should be able to trim them somewhat appropriately.

    You can't use L pads with most piezos. If you're only using one you shouldn't need it anyway, they only have 93 dB or so sensitivity.

    Thanks, I think I probably knew that years ago when I was paying attention...

    70777121 is a peavey part number used in older 410B cabinets

    the 410TX would use a Sheffield TVX 1035

    both speakers are somewhat similar produced by Eminence

    basket is same old stamped steel used for many eminence speakers and somewhat similar to a Alpha or Beta
    Beta would use larger magnet and 2" voice coil Alpha uses a Smaller magnet and 1.5inch voice coil

    its a OEM design looks use a cheap smaller magnet like a Alpha but TS parameters wont be the same cause peavey is known to still try and make
    bullet proof speakers. Just like the Sheffields for bass its lower cost magnet but they use heavily reinforced speaker cones. So a alpha might have a 20 gram cone but peavey cones will be close to 40 grams so this will change the TS parameters.

    Just like the Sheffields and many other Oem designs its basic 20 to 30 ounce magnet and the EBP will support sealed or vented and has a FS of roughly 50hz. Meaning it will use the same .9 to 1.3 cubic foot box sealed or vented and perform fine with a 50/55 hz tuning for vented applications

    In other words the same old 1 cubic feet per driver at 55hz will work fine
