I purchased these speakers along with the signature center speaker to upgrade an office 5.1 surround sound setup from some "home theater in a box" Onkyo speakers. I was concerned the upgrade would be so marginal that I'd have buyer's remorse, or that I'd regret not purchasing the less expensive Polk option. I am happy to report that not only was the upgrade in quality clear from the moment I ran sound through the system, but that it far exceeded my expectations. The speakers were significantly larger than the ones I replaced; calling them "bookshelf" speakers seems to suggest an assumption of quite the large bookshelf. Better to think of these as "mini floor speakers" even though no sensible person would set these on the floor. For a desktop, they're perfect though, giving me the experience of floor speakers on the desk. Every minor audio detail of a video or game shines through these speakers, from crickets to footsteps to explosions to conversation. The audio is just incredibly dynamic and doesn't sound or feel compressed the way it could in the smaller speakers. Plus they just look amazing, especially with the front grille taken off. The silver and black inside the walnut grey box looks really clean and crisp. I'd purchase this again and would definitely highly recommend it to others.

Okay So I currently live in an apartment because I am in the military and constantly move. So I have to worry about bothering neighbors. This is a problem when setting up a system for movies and music. I was extremely decisive on looking for the right speakers on a budget and really wanted to avoid getting a subwoofer because of how well the sound travels to my neighbors apartment just down stairs. So I bought some Sony speakers and they were wayyyy to intense on the high end. I have a small bay audio center speaker which is a perfect balance of highs and mids. I purchased these speakers in hopes for a really strong mids presence with just a little low end. I have a Yamaha aventage reciever and tuned the system in with the ypoa mic and I was blown away. In my small apartment I almost have to be careful with my volume adjustments because the mids and lows are so intense through these speakers. The theater offers a very crisp high end and the 5.25” speakers give such a clean mid/low sound. I listen to anything from alternative/classic rock/grunge/hip hop to electronic music. And these speakers have not disappointed yet. Time will tell through the break in period if they still are this awesome. But I am almost confident I can avoid buying a subwoofer altogether with these two speakers and my small bag audio center. Another thing, I can turn my volume to 90 percent with no distortion and very stable levels across all spectrums. I haven’t went 100% due to my neighbors.

These are primarily an upgrade from my Bose 301 I must say from the beginning I could hear more detail Clara and three-dimensional soundstage Imaging from the speakers when I added the subwoofer it completed the package and gave me outstanding stereo sound these are very noteworthy and I would recommend anyone who is looking for a very reasonably priced but outstanding sounding bookshelf speaker to give these a try

Polk audio signature series are by far the best I've purchased. The sound quality is superb. Playing music you will hear every instrument with clarity. Watching movies will bring scenes to life. This purchase brought my sound system to life and I guarantee Polk signature series will not disappoint.

So far so good! Nice, crisp, clean sound, with good bass on this bookshelf speaker.
