IF you’re a fan of Polk Audio speakers, here’s something new from the company – the Reserve Series, aimed at hi-fi and home theatre enthusiasts looking for butt-kicking performance on a modest budget.
Polk tells us the the Reserve Series features “our transducer array that we released with the Legend series… a new Hi-Res Pinnacle tweeter and new Turbine Cone, combing to give a flagship sound. Polk Reserve will feature two new technologies – Power Port 2.0 and X-Port. All pieces combined deliver an amazing sound at the fraction of the price versus competitors.”
The line-up comprises two bookshelf models (R100, R200), two centre-channel units (R300 and the slim R350), three towers (R500, R600, R700) and the R900 “height module” (Atmos, essentially).

“The Reserve Series uses the same custom-made transducers originally developed for Polk’s award-winning Legend Series loudspeakers,” says Polk Audio president Frank Sterns.
“Featuring the proprietary Pinnacle Tweeter, Turbine Cone midrange and Polk’s latest bass-management and resonance control technologies – PowerPort and X-Port – the Reserve Series delivers Polk Audio’s signature quality sound at an approachable price,” Sterns adds.
We’re told that Polk Audio engineers created “rigid, internally braced cabinets while leveraging driver and port technologies from the Legend Series speakers to achieve breathtaking levels of balance and realism.”

The Pinnacle Ring Radiator tweeter features a finely-tuned waveguide to dramatically improve the dispersion of high frequency energy, ensuring a broad sweet spot, while the critically damped rear-chamber helps defeat unwanted resonances. Turbine Cone midrange driver combines Polk’s proprietary foam core driver design with molded Turbine geometry, which dramatically increases stiffness and damping without adding mass.
X-Port Technology, making its debut here, uses a set of closed-pipe absorbers precisely tuned to eliminate unwanted cabinet and port resonances. The Power Port 2.0 design is a Polk-patented loudspeaker port application that enables bass frequencies to extend more deeply and at higher output levels than traditional ported speakers.
The Reserve Series is now available in black, with white and brown options planned for June.
Nice to read your post. I really like your post. A few days ago I wanted to build a home theater in my flat, but I didn’t know how to do it. I understand from reading your post. Thanks for sharing with us.
