    Hey Brian, I guess I should have asked is there even a brace between the midwoofers to measure?

    The repurposed JBL cabs I saw had a thick coat of roofing polymer brushed on the inside.

    Yea there's a 9.25"x9.25"x.75" brace. I beveled down the top edges for a little extra clearance for rings. I wish I'd done something completely different while they were out. But that ship has sailed...

    I'm still looking forward to how the eggs are incorporated--always looking for ways to improve my 2BTL!

    "Huevos" in Mexican Spanish (which is mostly slang) refers to having guts or balls.

    Very cool. Reminds me that I've got a full set of Jantzen inductors to put in place of the stockers.

    May I ask how you secured the SDA inductor to the floor? That's the one detail I haven't worked out yet. (Is that a Northcreek inductor?)

    They're Northcreek. I bought them off of Larry awhile back.
    I'll take some pics when I get home. Mounting the inductors turned out to be really easy.

    Just make sure the screw or bolt is non-magnetic, either stainless, brass or even aluminum.

    So I used these t-nuts and some stainless all thread that welded at the bottom. Then these plastic spacers that I made fit into the center and that's what holds this whole thing in place. Plus I added a rubber gasket for them to sit on.

    Didn't you make some billet tweeter plates for these? Thought you did.
    I cannot find your old posts and wanted to check how you made the outer edges where they meet at baffle. Thanks

    I can't find the thread I originally posted that in but I still have some pics. These were all Larry's idea I just machined them. They turned out sharp.

    I've actually got a some more upgrades for these 2B's coming down the line eventually. But I'll have to put those on the back burner until summer probably.
