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-Bracketfor easy &  
secure installation. Nearly invisible from  
sightlines, the Stealth-Bracketincludes  
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/EASEinterface.

frequency dividing network shall have a  
crossover frequency of 2.27 kHz with slopes  
of 12 dB per octave (2nd order) for both low  
and high pass filters. Rated power capacity  
shall be at least 20 Watts continuous power  
(RMS) and conform to EIA-426-B testing.  
Maximum continuous output at 1 meter  
shall be 98 dB.
