    First post! I need some help identifying this bass speaker, I was told it was a mid 70's Ampeg Speaker...It's 10", the magnet measures 3.5" x 4.5", 1.5" depth. Any help would be appreciated. Thanks for looking!

    Made by the CTS company, 26th week of 1974. I think CTS stands for Chicago Telephone Supply, not sure. They made lots of speakers and Ampeg used a lot of them during that era.

    The "137" is the manufacturer's code for CTS. The "7426" means the 26th week of 1974.

    32 ohms indicates it may be from an early Ampeg 810 flatback cab. Got 7 more of them? The proper term for this would be "mojo".:smug:

    Yup, looks like CTS 10 made for the ampeg 8x10 cab. Has the same part number as mine, assuming the top one is the part number:


    Should handle about 30-50 watts tops. Are you planning on rebuilding the 8x10 or using it for something else?

    I was actually thinking of selling, I'm looking to downsize a bit.
