I spoke to the tech guy at Snell a few months ago. He has
B Minors, as I do. He said he didn't see any reason to get something new in the line.
I've heard that the Coincident Total Eclipse might be the way to go, if you like the Snell B's, though I've never actually heard the speaker. They're also the Absolute Sound choice in their category. The driver configuration is similar to the Snells, too.
