If you did a good job with the assembly, nowhere.

Any joint you suspect could possibly leak air. Although, I'd just smudge more PL in any questionable place.

If you apply enough PL, and have good “squeeze out” in the joint, you shouldn’t need to worry about caulk.
If you shone a bright light at the joint after it has set, and could see the light shining through, that might be a reason to put caulk on.
Hope that gives you a bit of an idea...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...

I've seen it on so many home-made boxes and thought "why?". This was after using PL, of course. Just like the Frank's Red Hot sauce commerical, "I put that $h1t on everything!".

Hey, Master Yoda. While still on the subject; could air leaks be created by using a flexible latex adhesive in a mdf box with high excursion drivers? We've all seen it used in car audio.

I've never used MDF with flexible latex adhesive, so I don't know. I've only used MDF once, and not by choice. Some 20 years ago I was sent a pair of kit speakers to review. They used MDF translam construction. When these small 2x4" loaded MTMs came in at 25 pounds I never again considered using MDF for my own designs.
