Product PreviewRTiA Series
Damped Asymmetric Hex Laminate
Isolation (DAHLI) Cabinet Design
Real Wood, Real High Performance
The new RTiA Series incorporates our latest Dynamic Balance
®
cone
drivers and 1" tweeters and elegantly redesigned cabinets that reflect
the latest styles. The floorstanding models feature “PowerPort
®
Plus,”
an enhancement of Polk
®
’s patented PowerPort venting technology.
As you can expect from this highly popular line, the performance
is classic Polk.
Damped Asymmetric Hex Laminate Isolation (DAHLI) Cabinet Design
for clean, accurate sound. The asymmetric design is made from
a 6-layer laminate with 5 viscous layers to create the optimal shear
damping (OSD) system, the process for which was specifically
developed for Polk. Their elegant styling aside, creating curved
cabinets not only results in a stronger, more rigid and acoustically
insert enclosure, but the curved walls also produce less audible
coloration from panel resonances.

i Models Feature The Latest Generation
Dynamic Balance Drivers And Tweeters The bass/midrange
drivers used throughout the RTi range employ polymer/mineral
composite cones.
1" Tweeter Is A Silk/Polymer Composite Dome for smoother
response and better detail.
A Neodymium Magnet, Low-Viscosity Ferro-Fluid Cooling,
and a heat sink on the back of the magnet, create better power
handling and reliability.
All RTi A Models And CSi A6 Center Feature Polk’s Patented
PowerPort Technology that reduces turbulence at the mouth
of the port. PowerPort vastly reduces “chuffing” or “port noise”
and provides deeper, more powerful, lower distortion bass than
could be achieved with conventional ported or sealed designs
of comparable size.
The Floorstanding Models,
RTi A5, RTi A7 And RTi A9 Feature
PowerPort Plus an enhancement
in PowerPort technology. PowerPort
Plus uses two ports (one front, one
rear) and internal “plates” to further
reduce air turbulence and increase
bass efficiency. A computer designed
tweeter faceplate radius, tapered
enclosure and baffle edge radius all
contribute to minimizing diffraction
for more open and spacious imaging.
RTi A7 And RTi A9 Use Multiple Long-Throw 7" Subwoofers
to combine the wide dynamic range benefits of a single large sub-
woofer with the tight, punchy, accurate bass response of small
woofers. Combined with PowerPort Plus, these multiple subwoofers
deliver deep high impact bass with speed and accuracy.
Magnetically Shielded to allow safe placement next
to televisions or video monitors.
All Models Feature Gold Plated 5-Way Binding Posts
with dual inputs for bi-amplification or bi-wiring.
Acoustically Inert 3/4" MDF Cabinets, finished
in cherry or black oak real wood veneers.
