I found the LSi15 to be somewhat bass-lacking. Personally I liked the LSi25 better with the built in active sub. My earlier adventure into Polk brought me a pair of RT-20p that I truly loved but kept having amp problems (Built-in 2-8" powered subs/speaker). Moved on to B&W Nautilus 804. Many people like the laid-back sound of the LSi15.
Polk LSi 15's
Hi Audio Fans, still playing with speakers in my system. I heard a friends Polk LSi15's and was quite impressed in his system. As a blues music fan-how would these speakers rate? Current amp is Rotel 1070 and Cary 308 cd.
