Summary: After breaking in the Polk speakers for about a year (during which they sounded better and better each month, they were slightly `bright' or shrill at first) I decided to try Klipsch speakers after hearing them decades ago at a boutique stereo store in Chicago. After plugging them in right next to my Polk Monitor 70 series II, I instantly noticed a louder volume level to indicate the increased sensitivity (efficiency of speaker).
Summary: I'm using these for my "B" channel on my Pyle Pro tube amplifier and they compliment my "A" channel 400 watt capable 10" monitors very well. I use them only for music, not movies but I'm sure they would be great for movies. They have a solid bass and clean highs. These Klipsch speakers are very good for the price. I also have a klipsch subwoofer to help with the low-end bass.
Summary: I have to give these speakers a four star rating. I really was hoping these would exceed my expectations over my dual 8 inch Sony speakers. They really didn't. As a matter of fact, my Sony's had better bass coming out of them. My receiver is a Yamaha RXV1800 with a Klipsch sub, center & rear surrounds. I wanted these fronts to complete the system. On the positive note, they sound really great for movies. Nice crisp & clear.
Summary: These blow their little brothers, the F-20s, and my old 8 inchers, Sony SF7000s out of the water. They compliment the F-20s very well, and the F-20s already had the Sonys beat. Massive bass for only two 8" woofers and a horn tweeter. They're paired up with an Onkyo TX-NR616, and it can be cranked to make them bump.
Summary: I am going to keep this short and simple. For a speaker of this price range it had the build quality of some no name budget speaker you buy at K-mart. Legs cracked easily and the edges of the speakers are poorly glued together. Before you buy and waste your time go into a store and take a closer look in person. I wish I would have done so!
Summary: To preface, I am a Klipsch fan. I have had a pair of their larger bookshelf speakers for a few years and love them. You will hear things from a Klipsch speaker that you've never heard from speakers with lessor tweeters. Yes, they can be shrill when used for music; but EQ settings can fix that. They are among the best home theater speakers you can get. The F-30's are some of the best bargains in audiophile quality speakers that you will find.
