At one point Axiom offered a Reference lineup, with the AX lineup - but before the ASW shaped AX lineup cabinets.

I have a pair of AX3's that are real wood. As good as the vinyl (I remember calling this Mac Tac in the 1970's!!!), real wood is much better. Of course, it is not a factor in the sound quality - although Totem I believe veneers inside and outside of all cabinets (or they once did) believing the cabinets would change - it certainly would change pricing.
