    I'll get the drill out and go to work.

    You might be right about the lugs. I'll test the caps while in there.

    Earl,

    That's really good information! I had a moment of enlightenment about the "potato masher" horns in there. It starts to make sense, but also spawns so many questions like: Can you...

    Cutting the plates for a 2308 on my CNC laser would be pretty easy. I just have to find a .bmp file or drawing of one plate and correctly size it. Its basically a rectangle, but the V notch specs...

    2307's are difficult to find, but I'm more curious about them than a week ago. Experiencing this type of horn before spending $$$ seems...

    Ian,

    The PT's are an option. They certainly are easy on the pocketbook! I think the stx825 horn (JBL part #5006815) at Reconing Speakers is the 1" horn.
