Big Sound for Small Spaces

Do you want to upgrade your home entertainment experience but worry about limited space? Polk’s TSi400 4-Way Tower Speaker with three 5-1/4" drivers gives you that big theater sound without taking up your valuable floor space. But don’t let its size fool you; these Polk Audio Tower Speakers deliver pure, powerful, room shaking sound without taking up too much room, or breaking the bank.

High Quality Components

Polk’s TSi400 gives you a lot of bang for your buck. Similarly priced speakers are built with inferior materials. The TSi400 enclosure is made from resonance deadening, medium density fiberboard (MDF). Other cabinets in this price range are made from flimsy particle board. When you look inside the enclosure, a silk-dome tweeter delivers crystal clear highs, while three woofers deliver deep and powerful bass. Tech talk aside, Polk’s TSi400 richly reproduces everything from Tchaikovsky to hip-hop and everything in between.

Audio Options Galore

The folks at Polk don’t cut corners with their TSi speaker line. The TSi400 has dual binding posts that allow for bi-amp or bi-wire connections. So, you can take advantage of all the power your amplifier has or use two amplifiers to get a wider frequency range and get the most out of your speakers. This is a feature rarely found in other speakers at a similar price point - only Polk Audio Tower Speakers bring this level of audio performance!  

Built for Movies and Music (and more)

Polk’s TSi400 4-Way Tower Speaker with three 5-1/4" drivers has a wide frequency range. It produces highs that are crystal clear and bass that is deep and powerful. Its broad soundstage and small footprint make this the perfect speaker for your home stereo system or front channel speakers for surround sound. No matter how you plan to use this speaker, Polk’s TSi400 will deliver lifelike sound with the power to virtually transport you into the front row of concert hall or the middle of your favorite movie scene.

The Power of Polk

In 1972, the founders of Polk set out to recreate concert quality sound in homes without charging outrageous prices for ridiculously large speakers. Their goal was to design an affordable, better sounding and more practical speaker. Times and fashions may have changed, but one thing has stayed the same. Polk is still crafting high quality, great sounding, affordable speakers.

Seamlessly Blends Into Your Décor  

Traditionally, if you wanted to get big sound, you had to spend big money on big speakers. Polk’s TSi 400 tower design takes up less than one square foot of floor space. So, you can get all of the dynamic sound you find at the movies and in concert halls without having to rearrange your living space.  And, if that isn’t enough, this speaker features beautiful wood grain, vinyl finish that blends in with your furniture so it doesn’t distract from the rest of the room.

What makes this a 4-way speaker? Speakers only on the front.
A shopper on Jul 10, 2020
  Thanks for your question. Technically, the TSi400 has only a 2 way crossover, at 2500 Hz. Polk Audio technical support is presently not available. We apologize for not being able to provide a definitive explanation.
