I have mounting brackets for the defcon III Speakers, they are from the old model but will work with the new ones. They are for 1 1/2 to 2".
I am getting the 2 to 2 1/2" for my new tower. If anybody would like to trade that would be lucky but ideal. If anyone is interested in these, I can make you a really good deal. I beleive that these will only work with the defcon speakers.
