Plenty of listening thru the years. Lots of time with both in the 80s. The LSI series from polk has always been what I considered nice. With Klipsch it really varys throughout their lines. I personally wouldnt dabble with either their lower lines as IMHO there are speakers I'd suggest before hand.\nI had some monitor 7s in the early 80s. Very musical but they had a tendency for blown tweeters. I know it was my fault because I liked to play my music Loud and I had a 100 watt Kenwood amp. Anyway up to that point the Polks were the best speakers I ever had but then in the mid 80s I acquired some DCM Time Windows. Problem solved no blown tweeters and even better sound. Ah the good old days.
