The aluminum basket will be stiffer. In theory, this equates to greater linearity through the woofers range of motion and that translates to less distortion.

In reality, I suspect that Axiom feels that you cannot hear the difference (which I expect they would have validated with blind testing) so they go with a less expensive stamped basket as standard.
