    Close, but Jensen and Utah were two completely separate speaker manufacturers. It's the standard Utah OEM driver made by Utah for Leslie and found in many late 60s and 70s Leslie cabinets.

    David I have had 4 or 5 Leslies from 1969 onward and they all had those Utah's in them.

    This always seemed odd to me.Why would any speaker manufacturer not put their name on their product?

    Exactly. You don't find "Jensen" on the C15s sold for use in Leslies either.

    You do find Utah's 328 EIA code on the Utah woofers, just as you find the 220 Jensen code on the C15s, even though, after ~1971, all the Jensen speakers were actually made by Rola and not Jensen Chicago.

    Utah also made an orange cloth-edge 4Ω woofer for SS Leslies.

    The Utah woofers are very well-made. I've only had to recone one of them compared to many C15s.
