I am going to round over the edges of an 18.75 inch wide baffle housing a Seos 15 and 15 inch woofer. Is a 1.5 inch round over sufficient? I’m concerned about the thickness at the corners if I go 2 inch. I was planning on a 1.5 inch thick baffle and 1.25 sides with a corner strip inside to make it thicker where I’m removing material. Moving to a 2 inch I would need 19.75” wide baffle.
Is there any benefit with 2 inch over 1.5? Can it hurt things?
The speaker is actively crossed.
I would prefer as narrow as possible for the baffle.
I require a round over for the grill type but can get away with 1 inch for that if there is no other benefit with 1.5 or 2 inch

I'll let you decide what's best overall after reading this section of a thread beginning here: https://www.diyaudio.com/community/...d-midrange-you-have-heard.405952/post-7591687
By using double 3/4" sheets you can use constrained layer damping and fit a 3.5" roundover.
The larger, the better. Read Olson's work on cabinet diffraction.

A study puiblished in a couple AA magazines found that to reach down into the midrange 3-4” was suggested.
Given a corner made with sheet material a bevel can fake a larger rounder.

Studies here suggest 5" is nearing the point of diminishing returns for the audibility of diffraction.
The method I showed can accommodate 5" if pared back to the corner strip.

Thanks for the replies guys. A round over that big would necessitate a box size that would result in divorce court, me living in a single wide, and listening to book shelf speakers. I guess a 1.5" will do then if nothing narrower than 3"-5" will do anything. Adding 6-7" to a box that allows a 15.5" driver would be nearly 2 feet wide. Drivers are all in possession. The rounded corners are needed for the grill type I'm using.
I tried.

If you do the math I posted, you'll find what's theoretically optimal for the panel width.
Right, hence Avalon's massive 4in thick baffles with the huge chamfers to minimise the direct / flat baffle area around the individual transducers.
Well, that was the idea with the early ones; it wasn't always quite as closely held to, especially if they wanted the baffle to support output down to the crossover.
That would be a section of a 10" Sonotube, or concrete form tube. I put Sonotube wings on my speakers. It worked but my wife did not approve.
