TOA’s HY-60D Series Brackets are used to change the directivity angle mode of the HX-7 Series Speaker System to 60° mode. Three pieces of the HY-60D Series are required to obtain 60° mode of directivity angle. The HY-60DB-WP and HY-60DW-WP brackets can be used outdoors, but only under eaves or in other locations not directly exposed to rain and the elements.
