Considering it's a 500 Hz XO, doing a dab of Elmer's glue or similar + maybe a tiny piece of TP shouldn't be audible since the WLs < its effective piston, patch diameters will be rolled off enough by the XO point/slope.

One speaker, with an interesting history:

Not all vegetables make good leaders.

i have the drivers and horns to make up a pair of these. the 909s diaphragms are 26420 pascalites. they look new.
This could be my next Altec build soon as i get moved into N Florida. House couple acres barn and no neighbors.

I'd go here and save ALL images if you;re serious about the build: ALTEC LANSING M500 crossover - MES ENCEINTES ACOUSTIQUES
I don't think you'll find that info anywhere else.

Interesting! I've been calling them 500 Hz due to what the distributor said way back when they got a demo pair in and no one's ever corrected me, so wondering if it's adjustable.
