I have a 100-R, it's deceptively loud. If you're standing right in front of it and the sound is blasting past your ankles you might be disappointed in the volume. If you're standing 4-5 feet away it comes alive and does a good job of filling the room with sound.
It depends on how loud/what type of band you're in, but in the right situation it will shine!!!! Congrats!
P.S. first dibs if you ever decide to sell it! :-D
