The Klipsch R-625FA is a passive floorstanding speaker that improves the surround sound of your home theater set. You perceive sound above you thanks to Dolby Atmos technology. The speaker reflects the sound waves through the ceiling towards your hearing. That way you hear objects from films and series flying above you. This gives you the feeling that you are on the film set yourself. The 4-way system splits high and low tones and sends them to the woofers via separate speaker cables. This allows you to enjoy a clear view of the medium-high tones. The tweeters are disconnected and made of titanium. This means that the high frequencies are audible.
