TSi

Bring out the best in your entertainment media with the loudspeakers of the TSi Series. With a high quality, heavy duty construction (that shows smartly in any room), and audiophile-level components like silk dome tweeters for detailed highs without fatigue and polycarbonate cone drivers for smooth, natural sounding mids, TSi makes a definite statement about your personal style. They’re priced reasonably to perform professionally and bring out the best in your media, whether old school or new.

Outstanding Performance, Amazing Value

In the days of audio yore, that is the 70s and 80s, high quality “audiophile” sound was mostly expensive and very mysterious. Polk was a hero among the people for breaking the cycle of expensive audio equipment, designing and engineering equipment that delivered real high performance at a rational, reasonable price. We did it by building the loudspeakers that we personally wanted to listen to: high quality, serious audio equipment that didn’t skimp on materials or performance. Our friends and fans appreciated that we left off the expensive pretensions.

The TSi Series is a great way to introduce yourself or your family to the fun and thrill of a home theater system. Build a system using TSi Series speakers, or use TSi Series speakers to complete a stereo system you already have. Add a subwoofer to deepen the impact and bring real excitement. Substitute the versatile OWM Series speakers as your rear surrounds in a TSi Series and save even more, without sacrificing performance at all.

With the TSi Series, your options are nearly endless, your performance nearly flawless, and your audio system totally radical!

Technology & Features

High Quality Cabinet Construction

Most other speakers in this price range are made of particle board. It’s flimsy, unstable, and doesn’t reproduce quality sound. The TSi speaker enclosure is constructed of extensively braced MDF with 3/4-inch baffles. It’s easy to see and feel how heavy and solid this is, and the braced construction eliminates internal resonances and energy-stealing vibrations, for more efficient operation.

Furniture-Quality Finishes

TSi Series looks much more expensive than it is. Beautiful pewter accents, a high gloss piano-finish black top plate and a removable black grille make TSi speakers a part of your decor. All models are available in your choice of stylish black or cherry wood-grain.

Dynamic Balance® Design Technology

Dynamic Balance is our patented advanced analysis of a speaker’s entire electro-acoustic and mechanical system. It helps us select better materials and more efficient geometry. With deep analysis, we can pinpoint and eliminate things that reduce performance before they become a part of the finished product. The silk and polycarbonate driver materials in the TSi Series are specially tuned to produce a flat, uncolored frequency response. This true transparency reveals a wide dynamic range, with sharp details, and no hint of strain.

Klippel Distortion Analysis

The state-of-the-art Klippel distortion analyzer uses a lasers and sophisticated software to do large-scale analysis of drivers in motion. We use this technology to test speaker motors (the moving parts) while they are still in the prototype stage. We can tweak voice coils and spiders for optimal motion, ensuring that a speaker will perform well at both low and high volume levels.

Narrow Baffle Geometry, Small-Driver Configuration

A one-two performance punch that results in smart styling and superior sound. First, multiple smaller drivers are combined for more overall driver area with less overall driver mass, for wider range, more spacious soundstaging, and better detail. Second, these smaller drivers are arranged vertically in a slender enclosure (TSi floorstanding speakers take up less than one square foot of floor space), and tuned to project sound over a wider area, so every seat in the house hears a prime performance.

Silk Dome Tweeters

Unlike horns or metal domes, silk dome tweeters deliver clear and detailed highs, without fatigue, even at high volume.

Bi-laminate polymer Cones

Durable, efficient, and tuned with our Dynamic Balance process, this polymer cone material produces smooth, natural sound.

Flared Port Bass Venting

Surprisingly deep, musical bass response is the result of our critically tuned flared port venting system. Flared ports minimize port noise ("chuffing"), and smooth the turbulence of port air flow, to reveal big, full-bodied bass that blends effortlessly with the speaker’s overall dynamics.

Timbre-Matched to Other Polk Speakers

The TSi Series is timbre-matched to other Polk loudspeakers, so you can mix and match them to build or add to existing systems.

High Efficiency Design

TSi Series speakers are design especially to be driven well by practically any electronics, even the most modestly-powered amplifer or receiver. Whether you’re connecting them to the newest digital processor, or to your vintage rig, TSi Series produces sound that’s spacious and clear, warm and realistic.

Premium Crossovers

Our high performance crossover system to boosts performance with premium components, like mylar bypass capacitors to extend response in the higher, more detail oriented frequencies.

Magnetically Shielded

All models of the TSi Series are engineered to be safe when placed near sensitive AV equipment like monitors or TVs.

Gold-Plated 5-Way Binding Post Connectors

Dual (bi-ampable) gold-plated 5-way professional binding post connectors give you maximum signal transfer and the most secure professional connections.

Stable Footing

Floorstanding TSi Series models feature fat stabilizer feet to make a solid stand on both carpet and hardwood floors. Stabilizer feet help these deliver more precise bass response and superior imaging. Staying stable ensures that all the energy that moves your drivers never moves your speakers, so your speakers don’t dance to the music (only you do).
