I'm running 4.5 in the main room consisting of active LFR1100 driven by an ADA-1000-8 and a 1500-2, QS10 fed by an ADA-1000, one 800, two 600 and two 500 subs. No centre channel needed. Sources are an 8 year old Onkyo with a firestick, PS3 and Yammie cassette deck. And a karaoke.
In the living room I run M5OW with dual 125 subs fed from a Pioneer and a Chromecast audio. I just replaced my M2OW there. Frankly, there was no need. As Rebulx just discovered, the M2s and a sub are all that most people need.
I have Audiobytes, M50v4, M3v4, M2v4 and M5v4 bookshelves in other rooms. My friend stole my M100s when I wasn't home. He and his wife have locked themselves in their home and aren't answering their phones. When I go over, all I can hear is the M100s playing.
I also have an Air Force and Freedom. I use both to stir trouble with the neighbors outside.
Cherry cinnamon...nice. If you saw my various walnut finishes and cherry chestnut, you'd want them.
