The Polk Reserve Series home theater bundle pairs the R350 slim center channel speaker with the R100 bookshelf speaker to deliver an immersive, high-fidelity audio experience. The R350 center channel speaker features a 1" Pinnacle Ring Radiator Tweeter and four 4" Turbine Cone Woofers that produce clear highs, smooth mids, and deep bass. Its slim, sealed enclosure can be placed horizontally as a center channel or vertically as left/right surrounds. Meanwhile, the R100 bookshelf speaker packs a 1" tweeter and 5.25" woofer into a compact cabinet with rear-firing bass port for impactful lows. Both models carry Hi-Res Audio certification and support Dolby Atmos, IMAX Enhanced, and hi-res formats like DSD, FLAC, WAV, ALAC, and MQA. Cross-braced cabinets minimize resonance for purer sound. The speakers' sleek aesthetic blends modern style with smart engineering like acoustically inert grilles and large binding posts for easy connectivity. While the R350 anchors dialogue and effects in cinematic audio mixes, the R100 adds dynamic range and dimensionality as front, side, or rear surrounds. Together, they create an enveloping listening experience with pristine clarity across the frequency spectrum. Place an additional R350 vertically to complete a basic 5.1 system. Adding floorstanding, center, and height speakers from the Reserve lineup builds an even more impactful home theater.
