The Mid-Weight Champ
Approaches the performance of the RTi A9 but in a slightly smaller, more economical package. RTi A7 has two 7" bass drivers and one 6.5" midrange drivers, but still features PowerPort Plus and solid cabinet construction just like its bigger brother.
RTi A Series Speakers sound as great as they look! The perfect solution for a premium home theater or music system, these speakers will make you think you're in the movie or front row at the concert. RTi A speakers feature HUGE dynamic range- suitable for today's high resolution and high impact sources such as Blu-Ray, HDTV, SACD and HD Radio.
The September, 2008 Home Theater Magazine Review of the RTi A9 flagship system stated "The Polk system impressed me the most with its huge dynamic range in movies." Here is why RTi A speakers are so awesome:
