Prezes

Hi, I am planning to mount my R-14M to the ceiling using the following mount a Colytech SP-OS04 mounts: http://www.cotytech.com/content-product_info/product_id-2275/ceiling_bracket_for_large_satellite_speaker_sp_os04.html. There are two options: to attach the mount plate to the side wall of the speaker or to the top wall. Could someone advise which way would be better, as well as what type, size and number of screws to use? Thanks.
