Go into settings and switch them from small to large, or verify they are set to large/full range.
You're in for more upset when your center arrives.
Big left and right mains has never made any sense to me in a home theater 5.1/7.1 setup. A very high percentage (70-80%), of all dialogue comes from the center channel.
You're better off running 3 center channels for left/center/right in a 5.1/7.1 set up. Cross them all at the same frequency and let the subwoofers cover the rest. Full range towers have no place in a 5.1/7.1 setup anymore if you ask me. If it can dig to 80hz, good enough, I prefer 50-60hz though.
You're full range speakers are good for music stereo listening with no sub. I learned the hard way too with Cerwin Vega ls12s. 12" floor standers, and almost all the stuff that matters in a movie comes from center, surrounds, and subs. I'll never believe left and right mains need to be bigger then the center.
