OK, curiosity got the better of me so I calculated the increased area of the M22. If you compare the 1x6.5" of the M3 to the 2x5.5 of the M22, the M22 has 43% more cone area, a fair increase. It also ups the efficiency slightly and has slightly better power handling.

OK, playing with a power calculator, you are only going to get 2db more out of the M22. You can still reach 95db at 68w with the M3, at 4 metres. Given that this is well inside the maximum power handling of 175w for the M3, they should still sound good.

Interesting. I guess there really is not much difference in volume between the two.
