Specification Sheet

High Definition Pinnacle Ring Radiator Tweeter
Over 40 years of tweeter innovation, design and prototyping has
led to the development of the new 1” high definition Pinnacle
ring radiator tweeter. Developed by Polk Audio, it delivers ultra-
clear, crisp highs without unwanted coloration or distortions.
The Pinnacle tweeter features a finely tuned waveguide that
dramatically improves the dispersion of high frequency energy
ensuring a broad “sweet spot” while the critically damped rear-
chamber helps defeat any unwanted resonances.
Dual 5.25” Turbine Cones
Polk developed the Turbine cone specifically for our flagship
products to ensure the natural reproduction of the mid-range,
to which human ears are particularly sensitive. These Turbine
cones combine Polk’s proprietary foam core and molded Turbine
geometry which dramatically increases stiffness and damping,
without adding mass. You will hear every detail and experience a
smooth, detailed mid-range and effortless bass.
