Polk S15 is an excellent $200 bookshelf speaker from the Signature series, which also includes smaller S10 and larger S20 bookshelf speakers. Check out review on Polk Signature Series S55 floor standing speakers and HTS 10 subwoofer.
• Superb audio quality for the price
• Good bass for bookshelf speakers
• Beautiful design and look
Signature series has non-resonant Medite MDF cabinets quality with excellent build quality. It is available in either charcoal gray or walnut brown finish. The speakers look great with the grilles off.
S15 features 5.25-inch woofers and 1-inch Terylene tweeters. Like many of Polk’s speakers, the woofers feature Dynamic Balance technology that was designed in collaboration with John Hopkins University to minimize the effects of unwanted vibrations on the woofer. With frequency response range of 50Hz to 40kHz, it’s very impressive and better than almost every other speaker in the same price category. The speaker also features Polk’s Power Port that increases the bass response by about 3dB. You should still pair it with a subwoofer for movie watching but it can definitely stand on its own for music and low volume listening.
