    Disclaimer: I am not a review writer. In fact, this may be my first ever review on-line. I realize I am one of the first listeners of these speakers so I wanted to try and help people out. If you want any info not listed below ask in the questions sections and I'll try and get back to you asap. ------------------------- I love my new Polk Signature S15's!! I specifically wanted Polk's to compliment two surround RC85i (in wall) speakers and a Polk TL1 center I had already installed. I had originally purchased the RTI A3's after reading information on them for hours, but I didn't pay attention to their size... I figured as they were bookshelf speakers, that they'd fit on my (quite large and rather empty) bookshelves, but they were ridiculously huge so they had to be sent back. I'm pleased to say that these S15's fit nicely on my bookshelves and they look great. More importantly, they sound great. They're used mostly for music (Sonos and Vinyl) and I'm very happy with their performance. They're punchy and have a good bass response (I don't have a sub). I feel they are very clear sounding and fill my pretty large room well (30' x 15') either by themselves in stereo mode, or as part of a surround system. I'm no audiophile but I'm taken aback by having a nice audio system again (been about 10 years since I had a good setup). For the money, I believe I have found a speaker which is the right fit for me.

      I’ve had these speakers about three weeks now as part of a 7.1 setup. Installed in a large two story room, they are paired with a Polk S35 center speaker, four TL3 satellite speakers and a Bic Acoustech PL-200 II (12 inch) subwoofer. For music, the combination of the S15s and PL-200 is sonically excellent. I have listened to jazz, rock, reggae, dance, classical and R&B in order to get a complete reference on the speakers. The treble and mid range is clean and clear, while not introducing listening fatigue during lengthy sessions. The S15 bass is punchy while the PL-200 provides bone-rattling low end down to 22Hz. The combination is extremely impressive. At relatively high sound levels, the setup provides a concert or nightclub type experience, and has made listening to my music collection a renewed joy. Also, high resolution YouTube videos of live performances are a pleasure to watch, giving the illusion that you’re present at the live performance.

      For movies, the speakers, in conjunction with the rest of the setup, provide a real theater type atmosphere. The imaging and clarity are great. In all, I couldn’t be more satisfied with the S15s in this setup. For the quality that you get, they are extremely cost effective. I would recommend them to anyone, especially if paired with a good subwoofer.

      These are an excellent choice for either a music/home theater setup, as I have been using them in my living room. I have had both ELAC Debut B5 and B6's in that role previously, but was unable to accommodate their Debut C5 center channel due to the large size. I missed the clarity of the center channel, especially during movies so after a good amount of research I decided to give these a shot with the matching S35 center channel. I am very happy with the setup, and will consider moving these S15's to replace my surround speakers and getting a set of the floor standing speakers for the front left and right channels. If you are wondering how these compare to the ELAC, as I was before pulling the trigger, they are definitely in the ballpark. These have brighter highs, which brings a new level of clarity on detailed sounds, although I would give the edge to the ELAC for Music especially. In my mind the ELAC's really just nail it for music, giving you an incredible soundstage and imaging for the money. I still really enjoy listening to music with the Polk's, but it isn't as immersive an experience as before. If you are going to use your setup more for movies, you are definitely better off with these Polk's and their impressive center channel. It is a very compact size, and with the built in mount points it will make placement about as easy as you can get.

      I would highly recommend these, especially for the money. I went with the S15 because I have a sufficient subwoofer setup for the low end, but if you do not you would be better off going with the S20 for a bookshelf or stepping up to a floorstander S50/S55/S60. If you need something for rear surrounds, the S10 would probably be plenty for most setups. If you look at any photos of the 3 bookshelf offerings in this line, you will see that the S10 is a good amount smaller than the S15, with the S20 being slightly larger.

      I was setting up a new system for my gym/mancave and really wanted to go with Bose. I've sworn by Bose for 25 years, but after spending many pretty pennies on my gym, I decided to compromise (I thought) on the sound system. My setup is a 20yo Yamama receiver with the Polk PSW10 Bass, S20 front speakers, & S15 rear speakers...So this review is really for all the Polk speakers. Maybe it's just the different room, maybe it's the different setup, but these Polk speakers absolutely kill my Bose AM10 system (which has a brand new receiver). The bass is chest thumping. You will FEEL it, and if you have one, your wife tell you turn it down! I have the bass set to neutral on the receiver and only at 1/2 on the sub. Overall the sound is incredibly clean and crisp. And it is everywhere. Somehow it beats Bose's Direct/Reflect system in putting even sound in every corner of the room. The sound truly surrounds you, it doesn't come from over there. So, you know, I highly recommend this system. If I had the coin, I'd replace my primary theater system, too.

      The only down side is this: The speakers are big (relative to cube speakers). They will take up some space. They look sharp, so they shouldn't take away from a room's visuals or whatever, but you'll have to give these babies some space. If you're willing to do that, don't pass these up.

      Specific to the S20's & S15's, you *almost* don't need a sub. These both put out so much bass that you can turn that bass way way down and still have enough to shake the house. This is almost a negative for me, as I built my gym as far from the bedrooms as possible & still get complaints!!! But overall, for a fairly small speaker to put out that much bass really is impressive.
