To sidestep the question, there are similarly sized bits for a lot less money from several places. A 1.25" radius bit from Grizzly is $33.95 I used it on my latest project and it worked well, giving a smooth cut. I guess it would not last in a production environment, but that's not what I do. Bits that big are scary, even when the router is slowed down. I had to make a special base to accomodate its size.
I have no idea if it did anything to the diffraction, but imaging is wonderful. I am using a Focal 6W4254 and T120TD5 in a 10" wide baffle with a 1.25" radius roundover on three sides.
another possibility for large radii is to use ready made mdf quarter rounds. anderson international trading (aitwood.com) and tape-ease tapeease.com) are two retailers.

An externally hosted image should be here but it was not working when we last tested it.
This sort of approach is also valid.
But you can't argue with :

Here's a picture of my speaker If I can insert a picture instead of a link
Sreten, Is the top picture your DIY? Nice looking.
