The quality is further enhanced by the stylish non-resonant aluminum enclosure and the patented PowerPort bass venting technology. The curved enclosure breaks up internal standing wave resonance to create a pure, lifelike sound, while the PowerPort bass vents--which are hidden under the grilles--extend and strengthen the lower midrange performance to ensure a seamless blend with the subwoofer output. The resulting midrange minimizes the "hole" between the satellite and sub frequencies, helping male vocals sound rich and full rather than thin and weak, as with most other sub/slim tower systems.

Listeners can easily team Polk RM7400T tower speakers with other tonally matched Polk RM series models to create a 5.1, 6.1, or 7.1 surround sound system. Additional features include magnetic shielding, which lets you locate the speakers near a state-of-the-art TV or video monitor without distorting the picture, and five-way binding post connections for the purest possible sound. The speaker measures 5.8 by 36.5 by 6.62 inches (W x H x D) and is backed by a five-year warranty on parts and labor.
