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.

Data Acquisition

All performance data acquired at

SoundTube’s Technical Measurement

Center (TMC) are analyzed using a vari-

ety of standard measurement techniques,

including Measured Length Sequence

(MLS) and Time Delay Spectrometry

(TDS). Performance, development and

data acquisition tools include: Gold Line

TEF 20, CLIO, LMS, LEAP, and propri-

etary modeling software. EASE™ data

are acquired through an automated TEF

20/Outline/EASE^™interface.
