“[Polk has] hit the bull’s-eye with the LSi 9. Not only is it an exceedingly refined, first-class performer, it has specific sonic qualities that make it stand out in its price class.”

ARC® PORT

A loudspeaker’s internal standing wave resonance can impart a “thick” or “chesty” character to the sound of voices. Polk Audio’s patented Acoustic Resonance Control Port System is tuned to cancel this resonance for utterly clear, accurate and natural midrange.
