Real wood. Real high performance.

With a sound that's clear, clean and remarkably open, the RT25i is an amazing little speaker. Whether you're listening to music, or using it as a home theater speaker -- letting its real wood finish complement your naturally finished speaker stands or AV furniture -- you'll find that the RT25i images better than speakers costing many times its modest price.

The RT25i features:

  • Superior home theater and music performance
  • High efficiency for great performance even with low power receivers
  • Surprisingly deep bass response 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
  • Composite Dynamic Balance driver for wide response and low distortion
  • Improved Dynamic Balance Tri-Laminate tweeter, with vapor deposited micro-layers of stainless steel and aluminum for clear, detailed highs
  • Anti-diffraction bezel and grille system minimizes grille-edge reflections for more open, spacious, lifelike imaging
  • Available in three finishes, each standard at no extra cost: Maple, Cherry and Black Oak
  • Smooth, natural midrange reproduction thanks to patented Acoustic Resonance Control technology
  • Magnetically shielded for safe placement next to your TV with no picture interference
  • 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, one of our smaller bookshelf speakers, 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. We 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 in 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 delivering that performance. 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 RT25i (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! For build quality and beautiful sound, we're confident that you'll choose the Polk.
