Where are you seeing it listed as an option, Dave? I can't find it.

Perhaps instead of raising the $$ on V3's they took the spikes off the table? I use the rubber feet myself, spikes are still in the trays.

I have to agree with you Adrian. Taking in consideration the improvements on the v3 and Axiom decided it was not a good idea to raise prices I guess this was a good business decision since most people don't use the spikes. Although I would really like to have received them because of its looks.

The bookshelf models never included spikes.

It was reported by a somewhat upset buyer on another site. Axiom shipped them out free of charge, but it was communicated that they now cost $21.

As Ken implied/stated...maybe they are referring to bookshelf speakers which wouldn't require them(normally)? I don't see any indication that the towers don't come with spikes.

No, it was the M80V3.

Yeah I know the book shelves don't have spikes. That wouldn't make much sense.

Hmm. Seems like a reasonable change to me. I never used the spikes either. I wonder what other companies do? Ie: is there an industry standard/convention?

Yup, looks like you have to add the spikes via customize yours. $18USD for M80s, from what I see.

I'll bet most people use the rubber feet anyway.

Hard to say. I think I've got about 4 sets of spikes sitting in boxes, though...
