New Cast Composite Enclosure
SoundTube’s RSi Series cast composite
enclosure provides a low-resonance
platform with effective self-damping properties for a clean, tight sound. Compression
cast glass-fiber composite material coupled
with SoundTube’s patented ZeroReflection™ internal shaping provides extreme
stiffness and the elimination of internal
standing waves and external diffraction
distortions. The result is accurate sound
and tight bass in a high performance
commercial speaker.

Installation Options
The loudspeaker shall consist of one 200mm (8”) low-frequency
transducer with a frequency dividing network installed in a dual
ported enclosure. The low frequency voice coil diameter shall be
50mm (2”).
Hanging Cable Kit
Performance specifications of a typical production unit shall
be as follows: Usable frequency response shall extend from
33 Hz - 120 Hz. The loudspeaker shall be available with a
switchable transformer/4 Ohm input, and shall be equipped
with corrosion resistant gold plated barrier strips for both
impedance modes. Taps shall be nominally 8W @ 70.7V (16W
@ 100V), 16W @ 70.7V (32W @ 100V), 32W @ 70.7V
(64W @ 100V), 64W @ 70.7V (tap position not used @
100V). The frequency-dividing network shall have a crossover
frequency of 120 Hz. Rated power capacity of the components and
network shall be at least 125 Watts continuous RMS power.
Wall Bracket
SoundTube’s hanging cable kit
incorporates hanging and safety
cables in an integrated system for
easier and cleaner looking installs.
SoundTube also provides a wall

can be hung at 1, 8 or 20 feet below
the bracket.
The enclosure shall be constructed of a glass-fiber reinforced
composite for maximum performance. The grille shall be
constructed of heat resistant ABS plastic material.
Installation shall be by a single hanging aircraft cable with a 1/4-20
stud into threaded insert on rear input panel. A safety cable shall
be included as a seismic redundancy system. The external wiring
input connectors shall be barrier terminal strip and shall accept
from 16 to 22 gauge wire (or wire of any size using a blade terminal
input). Overall cabinet dimensions shall be no more than 316mm
(12.43”) in diameter, by 405mm (15.95”) in length, and weigh no
more than 9.55 kg (21.05 lbs).
Optional Accessories
Hanging Cable Kits 1, 8 & 20 feet in length, (HK1/HK8/HK20),
Hanging Cable Clamp (HCCL), Beam Clamp (BC1), Snap Link
(SL1), Forged Eye Bolt (FE1), Safety Cables 10 & 20 feet in length
(SC2-10/SC2-20) and Wall Bracket Kit (WB1).
The system shall be the SoundTube RS8SBi for both low and
high impedance.
