Hi,
I have not heard a Fender Passport so I can't comment on that. However, I own and use a Peavey Escort and find it very satisfactory when used at smaller venues. Sometimes, I use it as a monitor in combination with my larger PA system. As for the bass response I find it quite acceptable. Another positive I've noticed about the Escort is the projection. At 75 or 80 feet the speakers still have a clear "presence".
