I'm a happy owner of Polk LSi 9's for the fronts, LSi C for center, and LSi-7's for the rears, which I also use for mixing as near-field monitors. When I heard the LSi-9's I exclaimed "WOW!!!" quite loudly after hearing everything else our local Tweeter had to offer, and totally startled the salesman, who had never heard a customer reaction as strong as that!
