The Desono EX-S8 is an 8” two-way surface mount loudspeaker that provides detailed voicing with projection. It is an excellent fill or distributed loudspeaker for systems where pristine voice clarity, higher output and more bass is desired.

Designed for easy and fast installation, our innovative, patented ClickMount™ brackets provide installers with two distinct mounting options. The ClickMount pan-tilt bracket provides indexed aiming control and allows for mounting EX Series quickly in either vertical or horizontal orientation without moving the bracket position. The ClickMount U-Bracket is also available for low profile mounting or exterior use and includes the ClickPlug with an integrated gland nut for weather-resistant applications. Both brackets are theft and tamper resistant.
