The four satellite speakers can be wall mounted or stood around the room and are voice matched to the centre speaker for a consistant sound. These four speakers are taller than in the JBL Cinema 300 system and so may suit a larger room better. The centre and satellite speakers all use midrange drivers to improve efficiency allowing higher volumes and less distortion. In the JBL Cinema 300 only the centre speaker has a midrange driver. The subwoofer in the Cinema 500 has an 8 inch, fast-moving woofer with 150W amplification for realistic directional base to enhance your movie viewing. The subwoofer phase, level, and bass-boost can all be set to the specifics of the room or your own personal preferences. With colour-coded speaker connections and biult-in keyholes on the speakers, this 5.1 channel speaker system is easy to install, yet compact and brings quality sound to movies, music and video.
