Polk Audio's RM6750 5.1-channel speaker system gives you a complete surround sound solution for your home theater without breaking the bank. The integrated power port bass vent designed right onto the back of the compact satellite and center channel speakers-the same technology used in full-sized Polk Audio speakers-improves lower midrange response and all-important sub/sat blending, taking the RM6750 beyond the performance realm of any other sub/sat system in this price range.

Polk Audio RM6750 5.1-channel surround sound speaker set in black (see larger image).

This integrated design reveals midrange with no "hole" in the frequencies between the sats and the sub, for male vocals that are rich and full-not thin and weak like other sub/sat systems. It comes with its own subwoofer module--an 8 inch long throw driver and high current power amplifier for real ground-shaking bass thrills.

Key Features

• Satellites use a 3-1/4-inch (8.25cm) Polymer composite cone driver: lightweight and efficient, for clear, distortion-free midrange. The center speaker uses two of the same high quality drivers for even greater output capability.
• Integrated baffle and grille design allows maximum sound dispersion with minimum diffraction for superior imaging and room-filling sound. Everyone in the room hears clear, well-balanced sound.
• High performance 1/2-inch (12mm) silk dome tweeters for superior imaging and smooth highs.
• Mineral-filled polypropylene enclosures are non-resonant for great looks and natural sound.
• Individual satellites available to accommodate 6.1 or 7.1 channel systems.
• Integrated keyhole slot wall mounting brackets (two keyhole slots on center channel speaker) allow for easy wall mounting, with no extra brackets or wall mounts to buy; threaded inserts accept popular articulating brackets (sold separately).
• The Subwoofer, in a compact ported enclosure, features an 8-inch Long-Throw Dynamic Balance poly composite driver for longer driver excursion and better linearity, resulting in big, musical bass.
• Built-in Subwoofer power amp (50 watts continuous/100 watts dynamic power) with active crossover offers the control you need for real home theater thrills and big, musical, accurate bass. Features variable low-pass filter and volume (level) controls, as well as phase switching toggle, and signal-sensing Auto ON/OFF, for even more control and convenience.
