| One thing a smaller speaker does is spread the sound wider. The bigger the cone, the lower in frequency it will start to "beam". Meaning it puts it's middle and high frequencies out in a narrower beam in center and doesn't spread them as widely as the smaller speaker.
One would think 10's would be better to use than 15's for that, but, when you mount them in a square like you see in 410 cabs, they then act like one giant 20" speaker, and the 15 still has a better spread by comparison.
Rule of thumb is to stack the speakers in as close to a vertical line as one can in order to spread the sound more evenly about the room. Have better sound for more of the audience instead of a hotspot on center and muddier sound off to the sides.
For example, a pair of 210 cabs stacked on their sides to make a vertical column would have twice the horizontal dispersion as 410's mounted in a square.
