Subwoofer Dilemma

[PS3+HDDVD OWNER]

Ok guys.

I'm finally ready to take the plunge and order a subwoofer for my home theater. My budget will be about $500, and i don't intend on spending anything over that amount. I currently live in an apartment, so i really dont need an SVS or anything earthshaking right now. I need some opinions regarding which sub or sub(s) to go with. Here are the two subs i'm debating between.

eD A2-300 Elemental Designs has these listed at $350 on their website, but i'm not sure if they charge tax/shipping. This is my 1 sub option. Only issue, the things a tank and the finace' will not be happy!

(2) Acoustic Audio HD Sub 12's Equal bass distribution, right Big Daddy?! Listed at $200 each with free shipping, i have the opportunity to rock 2 of these bad boys! Only issue, the fiance' might kill me for not only getting 1 sub but getting 2!

These two options above are difficult to choose between. Both subs are sold exclusively online, so i cannot demo either of them. I've heard rave reviews about both, and i'm torn. I guess when it comes down to it, i'm leaning towards going with the 2 Acoustic Audio subs. I get 2 subwoofers, which will help enhance bass distribution, and i dont have to wait a month to get my woofer. Thats really hurting eD's chances on getting an order from me. Not sure why they still build those things to order when it seems like EVERYONE around here has one.

What do you guys think?

I'll list my setup the sub is going into below

Samsung PN50A460
Onkyo 605
Monitor 50 Fronts
CS2 Center
T15 Surrounds

Very basic setup as you can see
