The HY-CN7 Series brackets are used to join together two HX-7 Series speaker systems into a single system. Joining speakers together not only allows more accurate control of directivity for lower frequencies, but also enhances the audibility of amplified speech in locations that suffer from long reverberation times or high background noise levels. The HY-CN7B-WP and HY-CN7W-WP brackets are for outdoor installations under eaves or other areas protected from direct exposure to the elements.
