Polk Audio RTi A3 - Cherry (PAIR) Bookshelf Speakers

Tower Performance, Bookshelf Size
The larger bookshelf speaker with a 6.5" woofer and 150 watt power handling, the size will really fool you into thinking tower speakers are playing. Mark Marcantonio from Affordable Audio comments "The timbre and spacious presentation was dead on," and "The clarity of all vocals (no nasal or fuzziness) makes for an easy and non-fatiguing listening experience.

• Curved Cabinet Styling
The cabinets are specially made for both great looks and sound. The real wood finish is available in black or cherry, matching your furniture and room décor. A curved teardrop, asymmetric shape functions are both adding strength and to avoid the boring "box" look of other home loudspeakers.

• Dynamic Balance and Klippel Optimization
Like all high quality Polk speakers, the silk dome tweeters and bicarbonate drivers in all RTi A series speakers are both Dynamic Balance and Klippel Optimized. Klippel Optimization ensures the speaker will perform well at both low and high volumes levels. Dynamic Balance allows us to see the operation of the components on a microscopic level using lasers to reduce or eliminate artifacts that color the sound. So what do all these features do? When added up, they bring you a gorgeous looking speaker that sounds spectacular everyone in your household will enjoy.

• Patented* Bass Porting Techniques
Nothing is more annoying then dialogue that sounds chesty or boomy- the result of cabinet resonance. RTi A Series Speakers feature either PowerPort Plus, PowerPort or ARC Porting to reduce or elimate this noise.

• PowerPort®
Bass venting for superior clean, low distortion bass that you can really feel. PowerPort vastly reduces "chuffing" or "port noise" and provides deeper, more powerful, lower distortion bass than could be realized with conventional ported or sealed designs of comparable size.

• PowerPort® Plus+
An enhancement in Power Port technology. Power Port Plus uses two ports (one front, one rear) and internal "plates" to further reduce air turbulence and increase bass efficiency. PPP allows even lower frequency tuning and lower turbulence for less noise and distortion, and more big musical bass, even at lifelike volume levels. This technology delivers performance that vastly exceeds conventionally ported speakers with bass that you truly feel, as well as hear.

• ARC (Acoustic Resonance Control) Port
This technology suppress internal cabinet resonance to ensure clear, non-muddy midrange resulting in a more natural sound.

• Real Wood Finish
RTi A speakers have Damped Asymmetric Hex Laminate Isolation (DAHLI) cabinet design for clean, accurate sound. The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system and one real wood top layer for a beautiful finish. The process was specifically developed for Polk. Their elegant styling aside, creating curved cabinets not only results in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances.
Premium Connections
