Polk Audio RM6750 5.1 Channel Home Theater Speaker System is perfect for people who crave true cinema excitement without breaking the bank. The integrated Power Port Bass Vent designed right onto the back of the compact Satellite & Center Channel speakers improves lower mid-range response and all-important sub/sat blending, taking the RM6750 beyond the performance realm of any other sub/sat system in this price range. 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. The RM6750 comes with its own powered subwoofer module, an 8 inch long throw driver and high current power amplifier for real ground-shaking bass thrills. This home theater system is affordable and is high in quality.  It has clean and crisp audio with deep and rich bass. 

Polk Audio RM6750 is not the best system for audiophiles. 

Overall, Polk Audio RM6750 5.1 Channel Home Theater Speaker System is a good buy for someone who doesn't want to spend a lot on one, and also wants a fairly good quality system.  It brings home the excitement of dynamic, thrilling surround sound with deep bass for movies, games and TV.
