If I ever put a system in the garage, it ISN'T going to be my M80s




Well the Axiom system is already paid for, and the Rockets are now paid for, so does not make a lot of sense to sell these Axioms, and buy in walls. The weather conditions here in the valley is mild, no extreme colds, in the summer since the garage is on the north side of the house, it remains cool. No moisture, humidity is not an issue so they should be rather happy in that area.
I talked with Amie and she reminded me they have Axioms in the boat house, have had for several years and no problems, so I see no reason not to do it.
