NO, the concept is one mid directly aimed at the sweet spot, another is aimed at slightly left, and the third is aimed at slightly right. A tweeter is located in between the three mids creating a configuration of MTMTM. This will not create a true arc but the front of the speaker will look like a bulging front just to accomodate the slight toe out of the two outer mids. The tweeters will also be very slightly toed out to the left and right where the angle is between the center mid and the outer mid.

The theory is that the sound heard at the sweet spot will not be entirely different from the sound heard at the left or right of the listening area.
