Summary: Your first impression of these will be that they are terrible. Brand new speakers need many tens of hours of break-in (the manual specifies 100 hours, but that's probably to be on the ultra-ultra-safe side), and out of the box, you'll hear a whole lot of crunchy horn noise and little else.
Summary: Sound is smooth and crisp, especially in the mid rand and highs. expected a little more low end but does more than enough for my room size. Sounds good with many different types of music, but really shines with movies. I would highly recommend these to anyone.

Summary: I bought one of these speakers a few months back, when i first hooked it up to a small 25x4 watt amp i was blown away. I own a pair of Boss P12DVC Phantom subs, and these have more bass than the subs do. My favorite part about these is that they have an exceptional frequency range.
Summary: I just bought the Klipsch Synergy F20 speakers today, hooked them up to a humble Insignia 100-watt receiver with Bluetooth and a cheap Sony DVD/CD player and have been listening to music all night in a state of musical nirvana!
