Polk Audio loudspeakers shatter the boundaries of bass r
air turbulence at the mouth of the port can cause “port noise” and bass output losses of up to 3dB. (A loss of 3dB means that half of your amplifier power
is being wasted on turbulence instead of bass!) The distinctive design of the Polk Audio Power Port gradually slows air exiting the port, vastly reducing
turbulence, port noise and energy loss. The result is bass that you will feel as well as hear; bass that reaches out, grabs you by the lapels and shakes
you up—for a completely visceral and emotional movie and music experience. See more about Power Port at www.polkaudio.com/catalog/technology/.
