Polk Audio RTIA3B Bookshelf Speakers

Inside these bookshelf speakers lie advanced acoustical technologies. They contain the latest generation of Dynamic Balance® polymer composite drivers for smooth wide-range response with low distortion. In addition, a Damped Asymmetric Hex Laminate Isolation (DAHLI) cabinet design produces clean, accurate sound and a stronger, more rigid and acoustically inert enclosure. The warmth and beauty of the wood combine with the technology of a 1" silk/polymer dome tweeter for smooth response, while Mylar bypass capacitors in the crossovers deliver high frequency response and improve detail and transparency. Enjoy secure, versatile wiring applications with gold-plated 5-way binding post inputs. Also available in Cherry.

Product Details - RTIA3B

PowerPort bass venting vastly reduces "chuffing" or port noise and provides deeper, more powerful, lower distortion bass
Acoustic Resonance Control (ARC Port) technology allows for more natural midrange reproduction
Magnetic shielding for safe placement near video sources
Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency
Neodymium magnet, low-viscosity ferro-fluid cooling and a heat sink on the back of the magnet create better power handling and reliability
Butyl rubber surrounds for high-performance durability
Floating antidiffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging
All-MDF construction with massive asymmetric cabinet bracing ensures resonance-free enclosures for accurate sound
