The Klipsch R-51M is a set with passive 5.25 inch speakers for a small or medium room. Because of the 5.25 inch woofers, these bookshelf speakers come into their own in a small space. Place the speakers next to your television and enjoy detailed sound when you watch movies or listen to music. Thanks to the design of the sound box around the tweeter, the high frequencies move to your listening position. Together with the disconnected titanium tweeter, this ensures that you can easily observe all the nuances in the high frequencies.
