Sounds like a great result!
Is this the 'old' taller 115? If it is, FWIW, my experience with it was pretty much the same.
In a small room, it sounded just... OK. But at the gig, with room to breathe, it's a different thing entirely. It opens right up, the mids shine, the lows are so supportive, and I never felt like I needed to turn it up particularly loud. Even with my Walkabout putting about 180w into 8ohm, it was solid and authoritative.
