Get the perfect sonic experience for your
home AV system with the Polk Audio Csi
A4 Rti Series. It features 2 drivers
at its core - a pair of 13.34cm
Midrange/Woofers with Dynamic
Balance Polymer composite cone with Rubber Surround and a 2.54cm Dynamic Balance Silk Polymer
Composite Dome Tweeter. The speaker set has a frequency response range of 55Hz to 27KHz, producing thumping bass
lines, clear mid-range and sharp treble sounds. It also has a nominal impedance of 8 Ohms.
The Polk Audio Csi A4 Rti Series set
features proprietary curved 6-Layer
DAHLI enclosure design creating optimal shear damping for a more rigid and
acoustically inert cabinet for minimal resonances. Specifically designed for
reproducing accurate sounds, the cabinet features Klippel Motor Optimisation, which uses laser measurement technology
to ensure a smooth excursion path at either end of the volume spectrum for
uniform performance at both low and high volumes. The proprietary Dynamic Balance technology removes
system resonance, for minimal noise and distortion. Further, the speakers
feature durable, computer modelled
injection-moulded butyl rubber surrounds that supress unwanted cone
resonances for a lifetime of reliable sound. The Polk Audio Csi A4 Rti Series
features Cascade Tapered Crossover,
which eliminates the comb filtering and beaming, which is common to
multi-driver speakers. It improves sound quality and enhances the soundstage.
The speaker set features Dual
Gold-plated 5-Way Binding Posts for better and more secure connectivity.
The Polk Audio Csi A4 Rti Series features computer modelled anti-diffraction grilles,
which enhance the aesthetics while minimising sonic interference. It comes with
PowerPort Bass Venting, a Polk Audio
patented design for smooth transition of air flow from the port to the
listening area, eliminating turbulence and distortion, for a deeper bass. The Acoustic Resonance Control Technology
tunes out internal cabinet resonance, resulting in natural uncoloured midrange
frequency reproduction. The Polk Audio Csi A4 Rti Series features beautiful curved hardwood veneer cabinet
finish, with sleek and trim accents in various colours.
