Max, as you did with your amplification question, you're worrying about speaker changes with no good reason. Listen to your presently-ordered Axioms first. My M22s did a fine job on nearly all music(pipe organ excepted)when I used them on occasion in the past without a sub. There's almost no music content below about 40Hz, and my M22s have diminished, but still usable, response at 40Hz. If you want a sub sooner, a better change would have been to leave out the center speaker temporarily and use the M22s to form a "phantom" center, which they do in a fine manner.
