Floor reflection shredding resides particularly on lower mid. Subwoofers can´t climb that high to lend their helping paw.
Ok, you have studied things in practise "quite much". Very good.
Floor cratered single woofer -reproduced low mid may make midrange "sound better" (which is VERY subjective), although meter-technically quite probably worse. As strict meter man, I would just choose flattest response giving option, and not trying to judge by listening at all. Highly suspect that smoothness winner in real world M2 vs. 4722 -duel in room would be... 4722.
In my opinion 4722 is still only quite smallish two-way loudpspeaker, not needing particular long acoustical band/radiation -summing distance. 6 - 7 feet and upwards is enough for it, I would say. Its bigger (line source resembling) 3-way ScreenArray -brethren are different kind, though. Of course this directive big speakers resolution may be too much from 6-7 feet, if listener is not used to that kind of headphone -kind level of resolution from loudspeaker.
My general point taking part to this conversation was, that 4722 has serious advantage in its ankle holster, too. M2 is not sovereign, granted winner againts it at all, as many of you price tag worshipper -guys seem to think.
Our (HT) applications M2 is actually the one which more likely gets its ass kicked by 4722.
It doesn´t hurt either that 4722N is so much cheaper and fully usable in passive mode without dedicated DSP-amps, too. Even headphone output of mobile phone could drive this sensitive speaker to quite hefty levels, so can virtually every AVR on a market.
