Hi: I'm looking to get a subwoofer within the next few weeks. My budget is between $300-$400 cdn .Speakers are Axiom M-60's VP-150 room size is 19' x 12' x 8' with an opening to another room that is about 12 x 10, given that I'm living in an apartment these are the one's I'm looking at so far
Precision Acoustics 10" 150-Watt Powered Subwoofer (HD S10) $299 (has been on sale at best buy up here in Canada for $180)
PSB 8" Subwoofer SUBSRS1 at 2001 Audio Video for $399 or this PSB 10" Subwoofer SubSeries 5i $499. I have a gift card for $100 at this store so take that into consideration. I'm open to any other idea's out there just keep in mind my budget and do not want to tick off my neighbor's too much with the bass!

Thanks for any advice
