About the Product
Small in size, big in performance, the TSi100 is a great speaker to use for wall-hanging surround speakers in a TSi Series home theater (heavy duty wall-hanging brackets are built right in). Or, use them as main speakers in a small room, where performance is key but size is a consideration. Add a subwoofer to a pair of TSi100s and you have a truly dynamic high performance stereo pair for a truly surprising price.
The T15 are those bookshelf speakers whose high versatility is built to impress. Engineered with Polk’s proprietary Dynamic Balance® technology, they’re primed to improve your home theater experience and take on your entire arsenal of tunes without fail.

What customers say about "Size & Weight"
Polk Audio TSi100 Bookshelf Speakers
  • Excellent Speaker. I needed a compact speaker that could bump the mid and bass. I am replacing old small small satellite speakers and these are much better.
  • Paired this with my old receiver and replace my floor standing speakers. The sound quality is acceptable relative to the price and size. Looks great with the glossy black top and cherry wood side.
  • Great speakers. They mounted on my wall easily. Perfect size for my room. Nice quality and the sound is very nice, clean and clear.
  • I have never owned a pair of Polk Audio speakers before. My choice in the past was Klipsch speakers. I just like their sound their craftsmanship. But this has changed with the Polk Audio speakers. Excellent sound in a small size.
  • I've had these for about 6-months, and they've grown on me over time. I'm using them on my stereo in a medium sized room (10-ft ceilings, 24x20 room), and they fill the space wonderfully despite their small size.
