Default Baffle 36mm thick, do i need to chamfer?

I've just finished routing my baffles (2x18mm) for my ZRT 2.5 way sealed.

Should I do a 45" chamfer around the the woofer, or can I just use the same 1/2" rounding bit as i'll use on my baffle edges?

I would suggest a big champher is necessary if you want to avoid cavity resonance from screwing up your mids.

Round vs. camber. Two issues, you pick. Camber will have a sharp edge that is libel to produce refraction. Round over a bit more restrictive so if you expect really large cone excursions, maybe an issue.

I camber, then hit it with a flapper disk and smooth everything out trying for a horn-like profile.

It's CHAMFER not camber, champher, or camfer!

Champher & camber are both correct, chamfer would be an americanization of champher.

Once you chamfer the chamber you can clamber for some champagne, champ.

With the baffles, is there any minuses using 2x18mm mdf, instead of one piece 36mm?

I know it's hard to find large thickness mdf, the thickest I can find locally is 32mm.
But the suppliers can glue two thickness's together for me.

ps I did chamfer a 45 deg camber for woofer in a 25mm baffle

2 layers of 18mm MDF are likely better than 1 x 36. 3x 12 would be better yet. 2 x 12mm of quality plywood even better.
