eq max 12?

I have been doing some research and asking many questions, for 500 which is my budget. I can come away with an eq max 12 for that price, couldn't find a eq 15 within my 500 budget, will this be satisfactory for 11x10 room, I like deep bass and not boomy or muffled like the sw450 I had, is this a solid choice and price for this sub guys and will it outperform my Klipsch sw 450?

Just wanted to get some feedback on this sub before I pull the trigger, I seen the audioholics review which had nothing but good things to say about it however they reviewed the 15 not the 12 so I was wondering if any had the 12 version or any knowledge about it in relation to what my expectations should be?

I am mainly a movie guy and they I was told movies mostly only go down to about 30hz which is why this would be a good fit, any thoughts on this?

So which of those subs do you think is best, which would you go with and why, can you post a link of the one you think is a solid pick. I just liked the eq mic and remote for the eq 12, do either of these come with the same tuning options and are those items important?
