For the 2010s there was no Boom 2 so to speak. The Boom! speaker upgrade was just a 5 1/4" speaker that had it's tweeter mounted on the grill. It would be a drop in replacement for someone without an amp, but once you put a non Harley amp into play they are pretty much worthless. I bought a set because my stock speakers were worn out on my 2010 but only ran them for a couple of months.
