Expert Reviews:

"I am a little stunned by the Polk LSi15...outstanding accuracy, detail and nuance...."
Anthony Cordesman
The Absolute Sound, April/May 2002

"And they [LSi15] sounded fantastic! I expected them to be robust and dynamic -- and they were. What I was unprepared for, however, was how seamless their presentation of music was and also how refined they sounded."
