The black SM31-EZ-T 3" Surface-Mount Speaker with 10W Transformer from SoundTube Entertainment is a 3" surface-mount speaker that comes with a AC-SM31-XFMR transformer module to add a 10W transformer and 5 position tap switch that mounts into a single-gang deep junction box. The dimensions of this speaker measure smaller than a 4" sphere.
The speaker incorporates a proprietary attachment with indexed swivel-joint for complete hemispherical aiming. Components have been weatherized for indoor/outdoor applications. The speaker is engineered for rapid installation and low profile mounting for smaller venues. It is suitable for use in retail, restaurants, conference rooms, patio areas, educational facilities or any setting where full-range intelligibility, unobtrusive design and installation ease are paramount.
