The bass is acceptable. People said that it was quiet but it does live up to my expectations at least. The response is on point since I listen to a lot of metalcore. It shakes the room a tad bit but it wont shake the walls. I still have my Logitech Z-5500 sitting here if I ever feel like that for whatever reason.
If you want a loud punch - the Z-5500 is your best option (although now on Amazon they jacked the price up, and Logitech's new model is getting average to negative reviews).
Wow, you're right. On Amazon its 999.99 now. Does this mean my Z-5500's resale value would be much higher? I was thinking about selling it before I head off to college next year.
