This is a really affordable fun speaker that has more bass than I anticipated. I bought these as "bookshelf" speakers since I couldn't find any Polk satellite speakers at the time for my rear surrounds and if you have the room, they do an excellent job. The highs are clear and they easily reproduce dynamics. In fact I liked them so much at the price point I bought two more and a used amp so I could have good sounding music in the garage too : ) These speakers are great for surround channels, amp zoned bedrooms, small living rooms, etc. My son runs 5 of these (ES15) and a sub for his 5.1 setup as he needed something balanced between quality, affordability, and able to easy pack up since he lives on base. Polk has been excellent at providing a quality product in every price bracket and we appreciate that. These speakers look great too!

The sound, build and design quality of the Polk S15 is OUTSTANDING. For the the size of the speakers they put out impressive amounts of bass. I would overall give them an Excellent rating.

Bought these to put in the salon of a sailboat, but they were a bit large. Instead, I made them the rear surrounds in my home theater system, and took the OWM3's to the boat. These look and sound great, and match the rest of the all polk speaker system perfectly

Good bookshelf speakers for a very affordable price. I used these to complete the channel set up for my 11.1 home theater system.

I was pleasantly surprised to find Polk Speakers in my search. Many, many years ago I purchased 2 Polk 5JR 54034 speakers and a Powered Sub Woofer. My current purchase is the direct result of my satisfaction of these units.

The speakers sound terrific for their small size. I was a bit worried before I got them that they may not provide enough bass, but they do very well in that respect, and very good sound overall. They look really nice as well and have a quality feel to them. Very reasonable price and quick free delivery just in time for Christmas!

Great set of speakers! Happy that I chose these for a second set in my stereo system. So now my system is running two sets of Polk speakers.

The quality of sound for the money is absolutely astonishing. They could easily price these @ $289.99 Selling them under $220.00, makes people think they are a cheap loudspeaker. Sales and profit may actually improve if they were listed/sold in the $249-289.99 price range

Lacks clarity and brightness (seems soft in midrange. Do they publish a measured frequency response ?

Got these because I was using my surround system for music. Overall they sound good. Really sensitive tweeters. Very dependent on the source material. They can sound great, or overloaded & distorted. Overall I?m satisfied w/ them.

Excellent speaker for the money! Great mid range and highs, and a low end is surprisingly deep for the size of the speaker. Highly recommended!

Sounds are fair enough for a medium size room, but there are lacking on wow factor. The cabinet is made with cheap material. The wooden laminate got pulled when I remove the red congratulations sticker they put on them, now its lifted a little bit from the cabinet. Otherwise they are just ok speakers.

Okay, it started with a pair of Signature Series S55 towers for fronts.Was so impressed, ordered an S30 center channel. Also amazing. Decided to add the S15 for rears. This Signature Series if phenomenal! I have this system paired with an H/K AVR and 12? powered sub. The great part of the S15 is that the sum is not greater than the parts. These bookshelf speakers have a very dynamic balance of lows, miss, and highs. The highs, crisp and natural without fuzz or tinny, or too bright. The miss are clear and warm and not over powering. The lows on this speaker are just so good. So much power from such a small package. These would a wonderful option as stand alone fronts. I almost feel bad using such a balanced and wonderful speaker for a rear channel. I connected these to my other H/K 3700 2-channel receiver with a Pro-Ject Carbon EVO turntable and was blown away. I have a very large room with high ceilings (14?) and these little S15 filled the room very well. When using them as A/B speakers with the S55 towers on a 2-channel setup the sound strange that Polk Signature Series create is just phenomenal. It?s so clear, powerful, and natural. The S15 is just a great speaker and a great value. I am so pleased I might order some S20 bookshelf?s and upgrade to a 7.2 setup and get a couple of Polk powered subs. I finally have a grown-up audio system, than you Polk Audio for making this line of speakers at prices that working folks can afford!

Amazing sound for their size; they more than fill my large family room. The bass is incredible. You would think I was using a powered sub woofer.
