2–way bookshelf speaker with 5 ?–inch driver

The Do–It–All Bookshelf Speaker
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.


  • Unlike other speakers in this price range, TSi enclosures are constructed of extensively braced, solid MDF with 3/4–inch baffles. This virtually eliminates internal resonances and damps energy–stealing vibrations, for more efficient operation and more transparent sound.
  • Beautiful pewter accents, a high gloss piano–finish black top plate and your choice of stylish black or cherry wood–grain finishes make TSi speakers a part of your decor.
  • Polk's proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion–causing driver and system resonances, so you only hear the good sounds.
  • Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
  • TSi design combines smaller drivers (for more overall driver area with less driver mass) and narrow baffle geometry, for wider range and more spacious soundstaging, so every seat in the house hears a prime performance.
  • Unlike horns or metal domes, silk dome tweeters deliver clear and detailed highs, without fatigue, even at high volume.
  • Durable, efficient, and tuned with our Dynamic Balance process, TSi Series polymer cones produce smooth, natural sound.
  • Surprisingly deep, musical bass response thanks to our critically tuned flared port venting system, which minimizes port noise ("chuffing") and smooths the turbulence of port air flow, to reveal big, full–bodied bass that blends effortlessly with the speaker's overall dynamics.
  • All Polk loudspeakers are timbre–matched within their series, designed with the same components throughout, to achieve seamless speaker–to–speaker blending effects in multi–channel systems.
  • Our high efficiency design results in sound that's spacious and clear, warm and realistic, when combined with practically any electronics, even the most modestly–powered amplifier or receiver.
  • Our high performance crossover system boosts performance with premium components, like mylar bypass capacitors, to extend response in the higher, more detail–oriented frequencies.
  • Gold–plated, professional–style 5–way binding posts, for the most secure connection options.

    5 out of 5 eggsHi-FI ive this one!

    Pros: I have owned the TSi-100 for over a year. Purchased from Newegg with quick delivery and all intact. I purchased these for my modest bedroom system of a 2ch receiver and no sub as I have this play softly all night long. At night I turn the base all the way down. The sound is very good and you can listen to these speakers all day long. A very good bookshelf speaker. Mine came with a wall bracket. I have an unconventional placement setup but it works well for me.Don't pass this deal up! My brother-in-law has bookshelf speakers that cost him over $500.00 and to me they don't sound any better than these Polk speakers.

    Cons: You have to dust them once in awhile.

    Other Thoughts: These speakers sing with a good sound source. Poor recordings are just that but well done recordings will sound remarkable for a low cost bookshelf speaker.
