CENTER LOUDSPEAKERS

1" silk/polymer composite dome tweeter for smoother response and better detail. A neodymium magnet with low-viscosity ferro-fluid cooling and a heat sink on the back of the tweeter assembly, create better power handling and reliability.

ARC (Acoustic Resonance Control) Port reduces midrange “boom” for clear, natural midrange. Magnetically shielded to allow safe placement next to CRT televisions or video monitors.

Reversible design allows center channel to be “inverted” to fire up at listening position.

Damped Asymmetric Hex Laminate Isolation (DAHLI) Cabinet design for clean, accurate sound.

Finished in cherry or black oak real wood veneer. Anti-diffraction grilles minimize grille diffraction for spacious, 3 dimensional imaging.

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.
