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. See more about ARC Port at www.polkaudio.com/catalog/technology/.

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.
