Polk Audio TSi400 4-Way Tower Speakers with Three 5-1/4" Drivers Package Overview

Designed for crisp, clean sound, the Polk Audio TSi400 4-Way Tower Speakers with Three 5-1/4" Drivers features a four-way audio design that is sure to revolutionize how you listen to music or hear your favorite movies and TV shows. Featuring a pair of silk dome tweeters that accentuate delicate highs at any volume, this speaker set is designed to enhance high sounds like dialogue and treble, resulting in a truly realistic, detailed audio quality. The woofer offers a thumping, dynamic bass sound that is both warm and smooth, and the Dynamic Balance technology filters out unwanted distortion, vibrations and other system resonance. These speakers will pair with virtually any surround sound system, while the timbre-matched design allows for speaker-to-speaker blending in multi-channel systems, creating an exceptionally realistic sound. Small in size but with big sound, these tower speakers will add a missing element to any surround sound system. 

Product Information

Pair of Polk Audio TSi400 4-Way Tower Speakers with Three 5-1/4" Drivers

Step down in size from the TSi flagship TSi500 when you want big impact in a smaller room. Here, three smaller drivers in the classic TSi narrow baffle design make more efficient use of power, while delivering the same wide, realistic soundstage and deep, musical bass response you desire.


Polk Audio TSi400 Speakers Features:

  • 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.
  • Polks proprietary, patented Dynamic Balance technology allows the 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 (taking up less than one square foot of floor space), 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 the Dynamic Balance process, TSi Series polycarbonate cones produce smooth, natural sound.
  • Surprisingly deep, musical bass response thanks to the 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 speakers 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.
  • The high efficiency design results in sound thats spacious and clear, warm and realistic, when combined with practically any electronics, even the most modestly-powered amplifer or receiver.
  • The high performance crossover system boosts performance with premium components, like mylar bypass capacitors, to extend response in the higher, more detail-oriented frequencies.
  • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
  • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio.
  • Fat stabilizer feet on TSi Series floorstanding models make a solid stand on both carpet and hard wood floors, with the stability and efficiency to deliver more precise bass response and superior imaging.
  • All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industrys most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

Tremendous value
I was looking to replace some old tired vintage Advents and these Polks fit the bill nicely. I have a small listening room and they sound great turned down but if I want to crank up the music, they handle the job well. Overall nice sound stage with pretty decent bass on their own. I don't feel I need a subwoofer. Very pleased with the speakers and with World Wide Stereo!
