Dobrý den chtěl bych se zeptat jaký je rozdíl mezi reproduktory Polk Reserve R900 a Klipsch R-40SA popřípadě které by jste doporučili děkuji

The white Polk Reserve R900 speakers have adopted the best features from the flagship Legend speaker series. This is what allows you to indulge in superb sound. The Polk Reserve R900s are height units designed to complement your audio system. Their precision craftsmanship hides a range of sound innovations. The transverse bracing of the Polk speaker cabinet effectively eliminates internal resonance. Thanks to the rounded internal corners, sound is dispersed more effectively over a wide area with minimal diffraction. The Polk Reserve R900 speaker is Hi-Res Audio certified. This means you can enjoy a clean and detailed high-frequency response. With a minimum support of 32kHz, the speaker can also play the latest Hi-Res Audio files with enhanced sound extension (DSD, FLAC, WAV, ALAC, or MQA).
The Polk Reserve R900 speaker is equipped with a Pinnacle Ring Radiator Tweeter, which, thanks to its pointed shape, directs the dispersion of high-frequency sounds around the room. It is this innovation that widens the sweet spot, allowing you to enjoy music, films, and TV series no matter where you are sitting in your living room. A single 4-inch Turbine Cone mid-bass driver features a pioneering turbine design that significantly increases the cone's rigidity without adding weight. All this, combined with support for IMAX Enhanced, Dolby Atmos, and DTS:X technologies, will give you an even more satisfying experience when watching films.
You can easily mount the Polk height speakers in a way that suits you best. You can either place the Polk Reserve R900 directly on a compatible speaker from the Reserve series or mount it on the wall. There is a switch on the back of the speakers that allows you to select your preferred mode — on the wall or on a speaker. The Polk R900 will then automatically optimise its performance.
