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 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.
