Ok, so I thought this center channel speaker would be a nice upgrade over my 20 year old Polk Audio center channel speaker it replaced, but had no idea just how much the improvement would be! Sounds great in my Dolby Atmos setup with a high quality Denon receiver purchased this year.

    Great, natural sound. Sounds awesome at all volume levels.

Klipsch is generally out of my price range so it will be slow going the get the full set so I choose the Premier series and the RP-504C walnut center speaker as my first purchase. I was not only NOT disappointed, I was blown away! All of the reviews I have read were spot on.

Updated my Polk with this one today and listened to cds and just got done watching Star Trek Beyond. Omg super clear sound and a good tight one too. Now my Polk audio 20 year old towers need to be replaced with the 8000. That is the only draw back, money!

I've had the 504C for about a month now. Took longer then I expected to "break in" but now that it has it sounds even better. Upgraded from a small satellite speaker as my center watching movies is much more enjoyable with this bad boy!

Awesome speaker. Using with vintage JBL GHE1000v bi-amped towers and am very happy how the 450c compliments my system.

Great sound, a lot bigger than the other 4 driver that has the exposed screws. I think the bigger 2 driver would've been enough for me but at the time 100 dollar difference it didn't make sense.

I did a lot of research on center channels and was looking for something a bit more robust. This center channel has been well reviewed so I went with this one. I made sure to do some measurements with the furniture that I own since this is a larger than normal center channel.

    -Amazing crisp dialog that works well in low to high volume ranges-4 Support woofers for music/home theater-A great investment to a home theater setup

    - Make sure you do a measurement check to see if this fits an existing media console

The price was well worth the quality of this center speaker. Clear and quality sound from this speaker makes listening to music, games and movies even better. Overkill is an understatement when this speaker becomes a must have to any surround sound system.

Sounds as good as it looks! Couldn’t have been happier with my purchase. The only thing is that I should've got it sooner! I have it paired with Reference Premiere dual 8” towers along with the new and improved spl150 and spl120 bass cannons.

Loving this new Klipsch center speaker!! All vocals are crystal clear now and I can make out every word and I don’t have to turn in subtitles to hear what the characters whisper or mumble. Highly recommend!
