I just received my M2v4s as the Christmas gift to myself thanks to Axiom's generous discount. Enjoying M22V4+ EP500v4+VP150+QS8 for a while, I was always wondering what would be the ones for my second system in the bedroom.

Currently I use M3v3 pair with a small sub. It sounds good but I knew it could be better. Mojo and other guys are absolutely correct, M2v4 is what you need for a small room, near field listening or even larger room with a sub.

First impression is the big surprise that how come the big sound could come from the little pretty boxes. I could push the volume up without too much worry about the distortion.

Secondly, the soundstage is so wide and tall. Imaging is very steady and accurate.

Regarding the quality of the sound, it is very smooth and clean. One thing I noticed is that the bass is very noticeable even though it is not supposed be according to the specs. Then I realized that it is because the sound is so clean so the bass is clearly separated from the mid-range. Once you could clearly hear the drum and bass, I guess that mentally you feel the bass and are satisfied. This could explain why some viewers said that a sub is not necessary.

Comparing with M3v3, the improvement is apparent and justifies the upgrade. M3's sound is not as clean and the soundstage is narrower. Don't have a chance to check M3v4 so can't comment it. However I assume that M3v4 would have less clean mid-range because of the larger woofer but you get lower extension right?

Didn't see too much comparison between M2v4 and M22v4, so it is always my question, which one is better?

They both have neutral frequency response with 3DB (half power requirement) different efficiency. When adjust 3-5 db SPL, I don't find too much difference on treble and mid-range. Adding a sub, the difference is even smaller. However they are still different. Subtle but you can feel that M22 is little bit fuller. Is it because of the higher crossover? Maybe that's why I feel the SPL difference is 5db, not 3db. I will keep M22s as my stereo and HT FLR in my 1500cu sound treated theatre for better dynamics. M2 is so small, like others pointed, it is easy to place and disappear in non-dedicated areas without worrying bass management too much. Wife-approval as well:)

Keeping a low level listening volume, M2v4s would make you smile!
