Hey guys, since installing KX, I have used the Bass redirect. I was speaking with another member and they said because my speakers th LOgitech Z-640's have an internal crossover that I shouldn't use bass redirection. Moreover that because my speakers have a internal cross freq. of ~150Hz tha Bass redirection couldn't go below that. I could use Bass redirection to set my Theoretical crossover Higher that the factory installed one. Which makes sense, I guess. So to set my speakers up PROPERLY is hould leave Bass Redir. OFF? Can somebody give me the facts concerning this please? Just for my information
