I think one of the speakers in the 66 is damaged so I'm in the market for 6x9s

I have a higher powered head unit so I don't plan to run an amplifier and probably no sub any time soon so they need to be efficient (91db or better) and have decent lower end frequency response (<45HZ)

Oh, and budget friendly because I'm a cheap ass (<$200)

Any suggestions?

Also open to a good used set if you have any collecting dust.
