I beleive that the price changes based on the number of speakers in stock. More factory blemished M40's= less price.

A few months ago the FO M40's were on special for subscribers to the Axiom Newsletter. That was the $315.00 price.

It seems to me that Axiom is raising the prices on all the Factory outlet speakers as they did on their regular stock awile back. The price NEVER reverts back to the lower price.
