From the Manufacturer
The Polk Audio RM6752 Center Channel Speaker for RM6750, Black Finish (single) allows you to add a voice-matched back surround speaker in a 6.1-channel setup. The integrated Power Port Bass Vent designed onto the back of this compact unit is the same technology used in full-sized Polk Audio speakers, and improves lower midrange response and all-important blending for a great performance at a reasonable price range. This integrated design reveals a midrange with no hole in the frequencies, for male vocals that are rich and full rather than thin and weak like many other systems.
The RM6752 utilizes dual 3.25-inch polymer-composite cone drivers that are lightweight and efficient for distortion-free midrange, and a high-performance 0.75-inch silk and polymer-composite dome tweeter for superior imaging and smooth highs. The integrated baffle and grille design allows maximum sound dispersion with minimum diffraction for superior imaging, while the mineral-filled polypropylene enclosure is non-resonant for great looks and natural sound. The RM6752 includes two integrated keyhole-slot wall mounting brackets for easy wall mounting with no extra brackets or wall mounts to buy, as well as a threaded insert that accepts popular articulating brackets (sold separately). This center speaker is magnetically shielded for safe placement next to TVs and video monitors without causing video distortion, comes in a sleek black finish, and measures 11.1875 x 5.8125 x 4.3125 inches (WxDxH).
