    075

    All early Sovereigns and Olympus with S8R had the 075 mounted to the baffle with the split ring collar. Not until about late 72' (I think) did the 4 hole square mounting flange get added to the 075/2402/2405. Sometime in mid-late 73' JBL stopped using the 4 clamps to mount the woofs in the Sovereign and Olympus, and went to 8 tee-nuts behind the baffle instead. The correct way to mount the split ring is on the face/outside of the baffle (which yours is) with the white o-ring on the 075 against the inside of the baffle. You will see some with the split ring incorrectly mounted on the inside of the baffle. From the factory the LE15A was mounted on the side of the cabinet that had the 075. Trivia! Rick

    Oooops, could the answer be that simple?

    BTW, how does that work, putting two different woofers in a shared cab?

    Sovereigns

    Not two active woofers in this model - one active and one passive. Air tight cabinets only. Passive used to expand the low freq. listening area and is driven off the compression and rarfraction cycles of the active woofer.

    OK, many thanks! That would explain, why there are no wires on the right woofer.

    OY that would be the nicest truck in OZ, I'd reckon. I have a couple friends in Vic...one is a gov't research scientist who goes out of his way to try and kill himself at Surfer's Paradise regularly

    Not yours but a dream haul, no doubt.

    Oh yeah!

    Those are a nice pair! Big ol' beasties they are. The on-going curiousity factor always kicks internally in myself, asking just how would a pair of those sound?

    I think maybe this thread should have been titled
    "Ahead to the Past"!
    What we're talking about is discovering how great these studio monitors from JBL's "Golden Age" really are. These were always "digital ready" and capable of great sound reproduction at high levels using quality, efficient drivers.

    Just my .02

    Now you've done it, and I REALLY NEED to get those Stonehenges back in shape I believe it said in the literature--106 dB SPL?

    Just the thing to watch the opening to "Las Vegas" with!

    Nice to see those emoticons go for the burn too.
