Hey Michael, welcome to the forum!
The FRM-70 is a fairly small full range driver (2.5") but I guess you already know that.
It sounds best in ported enclosures I've found. It's quite efficient and surprisingly "full range" for such a tiny driver. Where do you plan on putting it?
I have 4 of these drivers I was planning on putting on the motorcycle. I've since sold the bike, so if you're interested....
