Bookshelf-75/LCR-55MkII/Center-55MkII/LCR-45 Bookshelf-75/Center-75/LCR-75/LCR-55 You will note that the tweeter in your LCR-55MkII and Center-55MkII speakers is mounted at a slight angle (4.7 degrees). This mounting is an integral part of the High-Frequency Prism System. When the speakers are mounted properly, the tweeter will be angled away from the listening position. That means that the surround channel speakers should be mounted with the tweeter angled towards the back wall of the room (when the speakers are mounted on the side walls), and with the tweeter angled toward the closest side wall (when the speakers are mounted on the back wall of the room). -

This speaker should be of the highest possible quality, and as similar as possible in response and radiation pattern to the left and right speakers. -
