Over 40 years of tweeter innovation, design and prototyping has led to the development of the new 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.

Hi-Res certified, the Pinnacle Tweeter is designed for today's two-channel music listening as well as multi-channel 3D audio found in movies, sports and video game soundtracks. 6.5" Turbine Cone 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.

The Turbine cone combines Polk's proprietary foam core and molded Turbine geometry which dramatically increases stiffness and damping without adding mass.
