Hey Papa D, nice to have another Iowa native around.
Keep in mind if you order 5 items from Axiom, you get 5%. Also, if you order from the factory outlet, which most of us do, you get 10% off, plus the 5% if you get 5 items. Might be something to consider, that way you might be able to get a matching sub.
I will tell you I like jazz also, one of my favorites is Diana Krall, my jaw hits the floor it sounds soooooo good, especially the stand up bass with a sub that can play low.
