Johnny,
I'm no expert, but I'd like to add my .02 cents to your last comment. You claim that the sub would not have had an effect on the performance of the Axioms or Ascends with the "thud" sound during SPR. And you state "Just like the other sounds I mentioned were more pronounced on the Axioms" (I presume you were talking about the highs on the Axioms).
I think Zarak is arguably correct that the sub would fill in some of the "thud" sound in SPR on either speaker. I've compared my M22's with and without a sub, and there is a big difference in the fullness of sound when using a sub. So I would be shocked if a sub did not have an effect on a "thud" sound or any other sound during the SPR beach scene.
Conversely, if the highs are better with the Axioms than the Ascends, then that is being caused by one thing, the speaker itself. There is nothing else to fill in the high end other than turning up the treble.
There is no doubt that the Ascends sound like excellent speakers, and could be preferable to some people over the M22's. But I would tend to support Zarak's comment that a sub would help any deficiency of the M22's with a "thud" or similar sound. Maybe I'm wrong though.
