Ok, I have gotten my speaker selection figured out, thanks to a lot of your inputs on here! Now I need a sub for my setup. This is going into a 15' x 18' room, that has a 12' opening on the back wall and the side wall, so it is very open. Which one of the following is going to give me the most accurate, deep, and loud bass: SVS 25-31 PCi $549 Hsu STF-2 $399 Adire Rava $399 Keep in mind I have completely blown my budget on the speakers, so I of course one of the $399 subs look better on paper, and feel better in the wallet! Is it worth the extra $150 for the svs sub? Thanks for the opinions guys, it is greatly appreciated!!!
