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. Hi-Res Audio
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.
5.25” 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. You will hear every detail and experience a
smooth, detailed mid-range and effortless bass.
Power for the Best Performance
70W or more per channel power amplification is recommended to
experience the best sound quality and performance.

Consumer Benefits
Crystal Clear Vocals For Your Home Theater
The center channel is the most important speaker in any home
theater setup. The Reserve R300 uses Polk’s latest flagship
transducer array to deliver clear, crisp, intelligible dialogue no
matter where you sit.
Cabinets Built for Better Performance
Polk believes cabinets should be beautiful and add nothing to the
playback. Polk Reserve cabinets, braces, and internal enclosures
are carefully engineered to minimize unwanted internal standing
waves and eliminate unwanted resonances. The result is a
cabinet that rigidly holds the transducer array while it faithfully
reproduces recordings.
