I can tell you about 2 years ago, I had never heard of Axiom speakers either until I started reading reviews on various AV websites. I've owned many brand speakers in the past, and I'll tell ya my Axioms aren't going anywhere, unless "Wid" talks me into M80's.
I know the Polk VS Axiom conversation has come up many times on this forum. I bet if you use the Search feature and look for RTi10 or RTi12, you'll find your information.
My recollection is that overall Axiom's have been favored, not so say Polk makes bad speakers, they don't. Axiom has been around for 30+ years, and is one of Canada's leading audiophile speaker manufacturers. The speakers are fabulous and the Axiom customer service after the sale is second to none, in my opinion.
Another option is to check out the Audition thread in the "Hearing Things" section, there might be someone in your area willing to give you a listen to these babies.
