SoundTube Entertainment SM31-EZ Overview

The black SM31-EZ 3" Surface-Mount Speaker from SoundTube Entertainment is an 8 Ω surface-mount speaker that incorporates a 3" polypropylene driver with butyl rubber surround. 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.
