The 60's can hold their own to their big brother. ;\) Not sure I understand the part about keeping up with the 150. The center channel is for movie dialog (voices). Unless the guy was playing in 5-7 stereo mode, the center channel is not designed to play like a full range loudspeaker, 60's or 80's, or 50's for that matter.

The 60's will rock your world.
