Life is good. You got the better house. The better furniture. The better car. But, why haven’t you gotten better speakers yet?

With understated elegance, the Reserve line has a minimalist design with universal appeal. Inheriting Polk’s flagship transducer array, the speakers produce exceptional sound rivalling competitor speakers that sell for twice the price. Immerse yourself in your favourite musical recordings or your weekly movie night with the new Polk Reserve.


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.

Flagship Turbine Cone Design

Using the same patented Turbine Cone as the Reserve line, this height module is timbre matched and positioned in the array to deliver an incredibly immersive Dolby Atmos and DTS:X experience.

Sleek Modern Design

Reserve R900 height modules are available in two modern finishes: Midnight Black and Satin White (coming mid 2021).

Fully Sealed Enclosure

The R900 features a fully sealed enclosure to prevent resonances and distortions.

Versatile Placement

The Polk Reserve R900 height module is designed to work with Dolby Atmos, DTS:X and other 3D formats. With the ability to wall mount or place on top of a compatible Reserve speaker, this height module allows convenient flexibility. Flip the switch on the back of the speaker to select the desired position and the speaker will automatically adapt to the optimal performance.

Timbre Matched for Unmatched - Performance

Designed with the same driver components of the Reserve series speakers, you can mix and match to create the ultimate home theatre set up.



"To create its Reserve Series, Polk Audio has leveraged technologies from its high-end Legend loudspeakers – including eye-catching Pinnacle tweeters and Turbine Cone drivers – while also introducing its first on-wall/on-cabinet height modules. A treat for system builders, the range has nine options, including a slim centre channel and three different floorstanders, timbre-matched to accommodate mix-and-match installs. The voicing favours neutral tonality, excellent detail retrieval and a smooth balanced bass response aided by Polk’s Power Port 2.0 venting technology – all attributes likely to set a home theatre fan’s pulse racing. While the Reserve Series’ understated design helps the speakers blend in to any room, its performance guarantees you’ll sit up and listen."


"I can still claim that the Reserve can measure up acoustically with more expensive systems, perhaps almost twice as expensive systems! Polk Reserve is highly recommended, even for those who may have budgeted for a higher total cost of speaker purchase."
