nowave hit it dead on.
I would put the JBL I the backyard even if it got hit by an occasional ball.
I would leave the Axiom in my living room and enjoy the music. One can also save a little more and just get a M22 paired with a cheap sub. Even that would shake the walls playing Sensoria or Kick in the eye.
