To Improve Audiox to be able to feel it also with 8 cases-----x to feel it with 6 cases---- In ITALIANO x sentirlo con tutte è 6 le casse,cosi mi funzionano solo 2--thanks

what?

Maybe he means surround sound? 7.1 = 8 cases (speakers?), 5.1 = 6 cases.

yep, he means speakers.
btw most modern audio cards or speakers have dolby pro logic or other things which can distribute stereo sound in the surround speakers
i use that method in the meanwhile
