I have seen some custom installers here start to use the LSi9 as a center chanel speaker. I got to watch movie clips & a short demo with the LSi9 as the center. The sound was much stronger ( I guess that is the term) than the LSiC & seemed the center was more active. Any input regarding using a 9 as a center. Im sure most of us has had times when we had to turn up the vol to hear dialoug. With the 9 it seemed that the 3 front chanels were equally as strong. ( the system I got to listen to had LSi15 front mains, LSi9 center, LSifx surround & LSi9 rears). Does the center speaker need to be a specific center to hear certin sounds, or dialoug? Should the center be weaker or not as strong as the mains? or as long as its timber matched it should work? Does a center chanel speaker have anything special or built differently? Any input is appreciated. Thanks!
