Polk Audio Lsi Series - Manual (Page 6)

POWERPORT ®
Polk Audio loudspeakers shatter the boundaries of bass response with patented PowerPort bass venting
technology. Conventional ports have limitations: 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 PowerPort 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/.

6 LSi SERIES LOUDSPEAKERS
PSW1000
The PSW1000 creates superb detail and musicality for truly
big, tight, emotionally satisfying bass you can really feel.
High roll surrounds allow longer cone excursion for louder,
gut-kicking bass. Both drivers feature vented, four-layer,
long-winding-height voice coils, vented pole pieces, and
Aluminum Formers, ensuring better heat dissipation and less
heat build-up for a long life of big bass. Both of the PSW1000’s
10" Dynamic Balance drivers are magnetically shielded, so you
can located PSW1000 near video equipment with no risk of
video picture distortion.
Dual 10" (25cm) Dynamic Balance drivers have nearly 40% more
surface area than a single 12"driver and a much greater force
to mass ratio.
Two Bass Venting Technologies—Slot Load Vent and
PowerPort
® combine to virtually eliminate port turbulence
and noise.
BASH Amplifier combines the fidelity of conventional Class
A/B amplifiers with the efficiency of Class D amplifiers. You
get high power, cool, reliable operation with precise definition
and low distortion.
Multiple connection options, including filtered line ins &
outs, speaker level ins & outs, adjustable-filtered Line In
and unfiltered LFE give you unprecedented hookup flexibility
and more control.
Heavy duty MDF cabinet with 1 3/4" (4.5cm) side panels
and rigid internal bracing control vibration for near-zero
cabinet resonance.
