I recently bought the Lsi-7's, and they sound great...should keep me satisfied until next year. While I save for the 15's. I was just wondering what are some of the advantages and differences on moving up to the 15's for music and HT?

I've read a few posts on the differences between the 7's and the 9's and I think I remember seeing a post between the 9's and the 15's I'll search for it.
Setup:

2 Channel: Vienna Acoustics Mozart Grand, T+A P 1230R, Primare SPA21, Oppo BDP-105
PC: Vienna Acoustics Haydn Grand, Cambridge Azure 650A v2 , Peachtree iDAC, Denon DVD-3800BDCI

    The 15's give alot more bass and play very well on there own without a subwoofer (for music - still need one for HT).

    I actually think the 7's and 15's sound VERY similar above about 100hz or so. More so than the 9's and 15's do. This makes for a great pairing for home theater (or SACD) use.

    Others may or may not agree with me, but my opinion is that the 7's for rears and 15's for fronts are as close a voicematch as the LSi series gets without using all the same speakers.

    My thought is that 15s sound very different than the 7s. 15s have a lot more air and throw sound to the rear of the speaker much more....also, 15s have a much larger presence. 15s dont need a sub for most music, and is very very good with acoustic music....To me, the 7s sound much more like a good conventional speaker with most of the sound seeming to come from in front of hte speaker....very detailed but does not have the airiness. I never heard the 9s but I speculate it will be somewhere in between the 7s and the 15s in that regard....

    I don't think I have quite as critical of an ear as some, but to me as already mentioned, the 15's provide a greater presence, obviously deeper bass, and great on their own for 2-channel stereo (if amplified properly). I even for a while ran them for home theatre without a sub in a small apartment and had all the bass I wanted (vibrated the couch). I have ran the 7's own their own in 2-channel with good results, but prefer the 15's. I've never ran the 7's as mains in a 5.1 setup (always surrounds) so can't really comment on that.

    15s are far better with regards to midrange realism than either the 9s or the 7s. Heard the 3 again at Tweeter and there was definitely no comparison when listening to 2 channel music... and this was on receivers.
