What makes the sound "bigger?" Is it the presence of the mid bass? The drivers are the same on the m2 and m22 as the m60 except for the 6.5s.


You answered your own question, with an added component of larger box size.
Making sound is about moving air. Larger drivers, larger cabinet, more air movement.

However, given your relatively small room, i would not have recommended M60s. You really need to sit a reasonable distance away to form a good stereo image, unless it is a one person sitting room or you have a small loveseat located around 8-10' plus away. The smaller speakers will fare better in a smaller room for setting up a good stereo or surround image.

If you have the chance to demo the M60 vs the M22, you will clearly see what i'm referring to as their difference in sound. The quality, tonal character is very similar. The best description i can provide is that the M60 is definitely the 'big brother' to the M22.
