Description

The SM400i is a 4” coaxial, ported

speaker with a low-profile surface-mount

enclosure design for indoor/outdoor

applications. Mounting hardware is

included & features a corrosion- and

theft-resistant Stealth-Bracket

™

for easy &

secure installation. Nearly invisible from

sightlines, the Stealth-Bracket

™

includes

uni-direction fasteners for tool-free, theft-

resistant security. SoundTube’s custom-

engineered driver and electro-acoustic

network deliver high-performance sound

in a cost-effective surface-mount speaker

design. The SM400i speaker incorporates a

5-position tap switch with voice coil/4 Ohm

direct for simplified ordering and stocking.

Provided port plugs can be used for added

weather resisitance.
