can't comment on axiom. i can comment on klipsch.
we have a dedicated theater with klipsch running off a yamaha 2700. i find the klipsch speakers to be great for theater. for the price and considering their high efficiency, i find them to be hard to beat for movies.
for detailed, critical music listening, i find klipsch has a little bit missing, but no big deal. in any case, i can offer one vote for klipsch for your theater. it has worked for me.
