    I just got a hold of an Ampeg V4 for free!!!! It needs new tubes, but other than that it is great. It's pretty beat up, but it has the best tone in the world. It's running through two fifteens and I want to know what brand these speakers are. They have goofy old square magnets, but they sure do sound awesome.

    Any info at all?

    Good Score........! Hagn on to it. It sounds all original. You prolly need a cap job more than tubes. It is not uncommon to have Old tubes last 30 years. Someone will know what speakers they are.

    Do you play in a band with those 2 15's? If so how does the V4 hold up volume wise? I've played a V4b and loved it and heard that the V4 is almost the exact same thing but a little cheap (and in your case MUCH cheaper!!!)

    Can you read any of the markings on the speaker magnets?

    Is the speaker cabinet an Ampeg as well? During that era Ampeg used CTS speakers, but they may have used others too.

    See if you can find any markings on the magnets and let us know what they are.

    i use one (v-4bh, the new one) in a pretty loud rock band. not the loudest, but we're not bashfull. it's loud enough for sure, but then i must add that i push it pretty hard. oh, by the way, i use a 2x10 and 2x12 set up to compete with a drummer and a guitar player using a bassman 100 combo with 4x10's. he's pushing it pretty hard as well. hope this helps. oh and by the way again, most people seem to think the v4 is cheaper and, "better" than the newer ones. i don't have any experience with the older ones, but i'm REALLY enjoying my amp.
  6. Square magnet = CTS (Chicago Telephone Supply), later CTS became Eminence, I think. There should be a 137-xxx date code on the back of the magnet.

    The only markings on the speakers are as follows:

    I don't know what this means, but maybe somebody knows.

    If they are CTS, that's good to know, but the number you mentioned isn't right.

    I hooked the cabinet up in my van to my Rockford Fosgate Amp to see how much pure boom they would put out. These things are amazing! I'm not really into noisy rumble, but these were great. The low, low end was outstanding and they were way clearer than I expected out of two old 15's.

    137 is CTS, but they haven't made MI speakers for a long while.

    Yes 67 is Eminence, yes to the date code.

    The 67 and 137 etc is the EIA manufacturer's number. One link giving many of the more useful codes is here:


    There may be another, it was the first i came to. Somewhere I have a listing in an EIA book.

    Eminence was founded by an ex-CTS engineer, and is currently run by his son. Good people.
