Real wood. Real high performance.

This tiny powerhouse of a speaker doesn't need much copy to set it apart from its peers. It's small enough to fit just about anywhere, with a real wood finish that looks great on the most prestigious naturally finished speaker stands and AV furniture, and sets new performance standards for speakers in its size and price class. It's available not only in the new real wood finishes of its fellow RTi Series speakers, but also in a matte white laminate finish.

The RT15i features:

  • Superior home theater and music performance
  • High efficiency for great performance even with low power receivers
  • Surprisingly deep bass response for such a wee enclosure is provided by a rear-firing Power Port venting system built into the speaker's back plate, which doubles as a convenient keyhole wall mounting bracket
  • Dynamic Balance® composite driver cone for wide response and low distortion
  • Anti-diffraction bezel and grille system minimizes grille-edge reflections for more open, spacious, lifelike imaging
  • Acoustic Resonance Control (ARC) Port System reduces unwanted internal enclosure resonance for utterly clear and lifelike midrange reproduction.
  • Available in FOUR natural wood finishes, each standard at no extra cost: choose from Maple, Cherry, Black Oak and Matte White
  • 5-way binding post inputs for the most secure wire connections

More About The RTi Series Bookshelf Speakers

When a floorstanding tower is too big, but you still want powerful, quality sound, Polk RTi Series Bookshelf speakers fit the bill perfectly.

Wood at Vinyl prices - The first thing you'll notice about the RTi Series is their luxurious real wood finishes: beautiful light Maple, inviting Cherry, and serious Black Oak (the RT15i is also available in white). What will really surprise you, though, is that you won't pay a premium for these distinctive real wood finishes. Because of our in-house computer controlled woodworking factory, we can offer these rich finishes at prices you'd normally pay for vinyl.

After the look, there's the sound. The RTi Series Bookshelf Speakers pack the unique Polk technologies found on larger Polk speakers -- like Dynamic Balance drivers and exclusive rear-firing Power Ports -- into stylish smaller packages. The RT55i, RT35i, RT25i and RT15i are bookshelf speaker systems boasting the sonic attributes of the best and costliest examples of the genre: superior linearity, definition and imaging at a price well within your reach. The bookshelf RTi Series produce bass that's rich, deep and satisfying - far beyond that of bookshelf speakers costing upwards of twice their price.

The RTi bookshelf models are intensely musical, presenting a large soundstage without sacrificing pinpoint localization, and are so transparent that they allow you to focus on the entertainment values of the performance without thinking about the speakers from which the performance is emanating. RTi Bookshelf Speakers are superb music listening speakers. At the same time, they possess the wide dynamic range necessary to make them great choices for home theater systems, particularly when teamed with a powered subwoofer.

Pick up the modestly priced RT15i (go ahead, pick it up!), then pick up a similarly-sized bookshelf speaker from another manufacturer. You'll immediately notice that the Polk speaker is heavier, more solidly built, and sports a superior fit and finish. Now compare the sound -- Go ahead, we said COMPARE! You'll choose the Polk, we stake our reputation on it.
