What do you guys actually think of the lsi's for home theatre? I am very happy with them musically but find that they lack in the home theatre department. Am I the only one? (maybe my center is to new still and hasn't opened up yet). Looking for your thoughts.

    Powering the 7's with exernla amps and an SVS and I couldn't be happier.

    I am using the Nuforce ref 9 on the mains and ref 8 on surrounds and center. The eights may not be enough for the center now that you mention it. But those 9's are more dynamic power than the lsi's can handle.

    Maybe my view is a little skewed as I heard those amps on some Ushers watching King Kong the other night. The sound was unbelievably good. Having said that I wasn't crazy about the tone of the Ushers for music though. A little cold and edgy.

    I love my LSi's for Home Theater. (I use my system for about 90% HT)

    The sound is great. I do need a better pre-amp (an issue I hope to solve as my next upgrade.) In all fairness, I do not have alot of audiophile friends, and do not have much to compare them to. (I have never heard the RTi's in a well set up Home Theater.)

    For what I have paid for my speakers and amplification I am VERY happy with my purchases and could not think of anything else I could have purchased for the price that would get me close to this level of performance. (I purchased both my amp and LSi's used)

    her is from the web site for the ref 9...
    Power/Load
    8 ohm 160W
    4 ohm 300W
    2 ohm 350W
    ...not bad, but not the greatest of specs. my setup can double the power all the way down to 1 ohm. They are very dynamic when i put in a movie that has a good dynamic range for the soundtrack... Some people prefer the sound of the lsi9 over the lsic. I think wingnut uses a lsi9 as a center. The lsi9 shoulds much different from the center. try to switch them around and see what i mean.

    In what way do you find them lacking in Home Theater? Detail, clarity, impact, ???

    What sub and electronics are you using with your system. For impact and slam, the sub is VERY important for home theater.

    Just curious.

    I am finding the soundstage to be a little smallish. Also, maybe a little brighter tweeter is probably better for home theatre. One other problem may be my source. Waiting for the new formats to come out and settle before I upgrade that however.

    Why do the lsic sound different than an lsi9? I don't have the 9's to compare. They have the exact same specs (crossovers, sensitivity, drivers). The only difference is they don't go quite as low but that seems quite insignificant. Maybe due to cabinet size.

    it is due to the cabinet design, and they use different crossovers. The specs for the crossovers are the same, but they are actually different units.

    Can somebody try to explain the difference in the sound between the lsi9 and lsic?

    Also those numbers on the Nuforce amps are a bit misleading. They are going to be more powerful than the same numbers of a ss amplifier. This is because they have less than .05 distortion at any volume level. Clipping is no issue at all. I have heard them wide open on gear (4 ohm Usher speakers) for an extended period of time. They were fantastic!

    I think one of the keys to LSI is just giving them enough power. I'm still fiddling with my system right now but I went to Frys today to hear what their setup was like and I was thoroughly shocked. They were powering them with a plain old 125 watt Onkyo receiver. The sound was so muddy compared to the setup at home with my Earthquake amp. The LSI's really like to have about 300watts if you can provide it.

    Not sure what you mean by that statement. There is no amplifier that can run "wide open" without clipping. I must just be misunderstanding your statement. Also you mentioned the Lsi's not having an adequate soundstage. Look at placement and associated source. You rarely hear about the Lsi's not having a good soundstage.
