Axiom Home Page Forums General Discussion Home Theater EP350 or one of the others?

I'm looking for a sub in the 600-700 range or so and was looking at the LFM1 Plus, VTF2 MK3, and for the heck of it the Sentinel cause of the size. My living room is 14x15 with vaulted ceilings and it opens up to the kitchen in back.
The current sub i have is a 12 year old pile of poo is 17"H, 17"D, 13"W jbl 100 watt. The catch is i'm trying to swap out the old sub with the new one without my wife noticing a major size difference. The Sentinel which i probably can't afford is close to the size and then there's the Axiom. I'm more into the Axiom cause of the price. Don't want to go over 750. If the Axiom does well for the movie stuff and the music (metal/rock) then i'll call them up today.
