Couldn't resist the comparison. Did you count the segments on the folding rule? That's right, 48"! LOL!
The Theatre 4 components go back in these which are prototypes for building the JBL2226 and Altec 811/806A into the same, albeit, smaller design. A quite valuable thing to do with a somewhat complex design like this. I developed a flow chart for the build process as some steps can't be done except in a strict sequence.
Veneer is next and then the woofer and horn sub-cabinets get connected.
Don't know if they'll make it to Lima, they'll each weigh about 150 lbs!
