Features:

• The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA9 cabinets are designed for clean, accurate sound.
• The two 5 1/4-inch midrange drivers are housed in their own tuned internal enclosures for increased clarity and lifelike detail.
• Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
• Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out the distortion-causing driver and system resonances, so you only hear the good sounds.
• Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
• The RTA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
• Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
• Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
• PowerPort® Plus bass venting is our patented design for smoothly transitioning the airflow from the port into your listening area, eliminating turbulence and distortion, for bigger, more musical, deep bass impact.
• All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
• Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
• Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high-performance audio.

Video Review:

Audiophile-quality sound from a great-looking tower
Our customers love the A9 — the flagship floor-standing speaker in Polk's popular RTi series. It combines a handsome, real wood veneer finish with the kind of performance that pleases even critical listeners.

This speaker's carefully designed drivers undergo laser testing to help identify and eliminate resonance points, ensuring a smooth, accurate response. Its asymmetric cabinet helps it deliver rich, clear sound by combating vibration and increasing rigidity.

The A9 also includes Polk's exclusive PowerPort® technology that reduces noisy air turbulence and increases low-frequency output. You'll enjoy clear highs, rich bass, and open, natural-sounding midrange.

Additional high-end features
Two sets of gold-plated five-way binding posts let you bi-amp or bi-wire the RTi A9 for the best possible sound. An anti-diffraction grille helps it deliver a large, three-dimensional soundstage with pinpoint-accurate stereo imaging. Adjustable spikes provide stability on both carpeted and hardwood floors.
