Audyssey can help to reduce some types of peaks for some locations in a room, but that's all.

Further, whatever bass peaks Audyssey improves for one location, it will not help other locations and will likely make them even worse. The only room I've seen Audyssey truly help was a cube, where peaks were the dominant problem. You can read more in my Audyssey Report
As Selden explained, improving acoustics is not as simple as adjusting a video display. However, that's no reason not to do it! Most people are clueless about the importance of acoustics, even people who consider themselves serious about home theater and audio quality. This short article is mainly about home recording, but all the same principles apply to hi-fi and home theater too:Acoustic Basics
