i am pairing it with creative x-fi elite pro, with the x-fi crystalizer you will notice the different. It also have bass boost too.

If you wish to improve the sub-woofer bass, you may try to change the connection cable to better quality one, i did changed mine to Van Damme blue series speaker cable, it really help. If you know some basic soldering, then can consider DIY to change the cable inside the sub-woofer as well.
