Single satellite speaker for the RM series 6.1 or 7.1 channel speaker system. Equipped with a single 3.5-inch polymer composite midrange driver. Frequency response: 40Hz - 24kHz. Equipped with a single 0.5-inch silk/polymer composite dome tweeter. Integrated keyhole slot wall mounting brackets. The Polk RM6751 satellite speaker accommodates listeners who want to add a channel or two to their existing 5.1-channel surround sound speaker system. Specifically designed for Polk's RM6750 setup--which itself comes with four satellites, a center speaker, and a subwoofer--the satellite helps fill out the rear effects, creating a true top-of-the-line home theater compatible with the latest surround encoding formats. Each RM6751 speaker is equipped with a 3.25-inch polymer composite cone midrange driver that's lightweight and efficient, along with a high-performance 0.5-inch silk dome tweeter. Combined, the drivers create a clear, distortion-free midrange and smooth highs.

120-Watt maximum input power. Center includes dual 4.75" driver with 1" tweeter. Rear speakers include 4.75" full-range driver. Nano-fine tweeter rated to 50kHz. New BRAVIA matching design. Create a cinema-like atmosphere and supplement your system with the powerful SS-CR3000 speaker package. Consisting of a bold center channel speaker and two dynamic front/surround speakers, this package adds dramatic depth to your listening experience. Designed to integrate with the BRAVIA design, this system looks as great as it sounds. The speaker also employs the same PowerPort bass vent technology used in Polk's line of full-sized speakers, thus improving the lower midrange response. The result is a midrange with no "hole" between the satellite and the sub frequencies, helping male vocals sound rich and full rather than thin and weak (as with most other sub/sat systems).
