Amazing Sound, Awesome Speaker
The most compact bookshelf speaker in the lineup, it sounds phenomenal for its size. A popular choice when used as home theater or music speakers. With a 5 ¼" midbass driver, it includes the same great sound in a smaller package.

Stereophile's Robert J. Reina loved the speaker saying, "I enjoyed every minute I spent with the RTiA1. The speaker's greatest strengths- the natural and detailed midrange, the excellent bass extension- are unheard of at this size and price, and its minor deviations from neutrality have been so carefully thought out and balanced that I wanted to mine my entire record collection, playing more and more different types of music."
