...who has access to a ruler. :^)

Hi, everyone-- this is my first post here. As I was researching vintage speakers to mate with an RCA 45 player (one of the "Slide-o-Matic" models), I immediately stopped and dropped my jaw to the floor when I ran across the JBL "Bel Aire" for the first time.

I picked it up, but it immediately dropped again when I found out what they sell for... :^)

Since that time, though, I've done quite a bit of measuring with the pictures that I've found on the web, and I think I've got the dimensions for just about every part of the little beauty... there are just a few that I can't quite seem to suss out. So, if it's not too much trouble, can someone tell me:

1. How deep is the bottom lip of the speaker box (the little shelf area in front of the face of the speaker)?

2. How deep is the upper overhang of the speaker box (it's probably slightly shorter than the bottom lip measurement)

3. And (if you have the back off of one)-- in the interior of the speaker, how far back do the two vent baffles (which I assume are made from 1/4" plywood) extend back from the inside face of the speaker?

Seems like a nice forum that you have here, folks-- thanks for any assistance you can spare!
