Help Picking a Subwoofer

[dukerock12]

i bought the psw110 at bb for 125 but feel like i can be getting better bass still. my room size is about 11x13. i have a carpeted floor. id prefer a front firing sub because ive had both a front firing and down firing and i can defiantly notice the front firing giving me a smoother bass for my room type. i really dont want to spend more than 200 dollars.

thanks for the help
