What does audisey adjust


I have a integra 9.8pre pro and a rotel 1075 amp. Inwall speakers and 2 small 10 inch subs. Movie Quality is good but 2 channel music is awful.Looking to upgrade main speakers . monitors or towers ? Also does audiseys baas management just adjust the lfe of the subwoofer or does it adjust front main speakers also if the crossover is set lower ths 80 hz.

Audyssey MultEQ XT equalizes all the speakers including LFE in the sub. Also, the LFE "crossover" is entirely independent of the bass management that reroutes main channel bass to the sub.
