Description
The SoundTube XT550 is a premium
2-way outdoor loudspeaker solution for
installations requiring high-performance
sound in a durable speaker design. The
XT550 is designed for full-range back-
ground/foreground music and paging.
The sealed, in-ground enclosure design
delivers true low end response (62 Hz, - 10
dB) and optimal off axis performance. The
XT550 includes theft-resistant mounting
hardware and a weather-proof 5-position
tap switch for 25/70.7/100 Volt applica-
tions with voice coil direct (4 Ohm) posi-
tion.
Applications
The ultra-wide 360˚ horizontal disper-
sion pattern makes the XT550 an ideal
choice for theme parks, promenades,
playgrounds, shopping malls, restau-
rants, resorts, gardens and other outdoor
applications. XT550 speakers come with
in-ground anti-theft brackets and stain-
less-steel square-tip screws for increased
outdoor security.

Reduce Overall System Costs
SoundTube’s BroadBeam® dispersion tech-
nology utilizes an advanced diffuser/tweeter
system to provide maximum dispersion of the
higher frequencies throughout the XT550’s 360º
horizontal by 40º vertical coverage pattern.
Designed specifically for outdoor music &
paging, the XT550 projects even coverage and
smooth response over a larger area than typical
outdoor speakers, with fewer units per install
– saving time and money on speakers, installa-
tion and amplifier power.
Enclosure Technology
XT enclosures are engineered for maxi-
mum durability and performance. Unlike
other outdoor speakers, SoundTube incorpo-
rates patented ZeroReflection™ internal shap-
ing to create the most effective environment
for sound reproduction. The result is accurate
sound and tight bass in an indestructible
enclosure.
Patented SoundTube
Technologies
SoundTube Entertainment is constantly devel-
oping new technologies that enhance audio
product performance. SoundTube Entertain-
ment innovations are protected by multiple
U.S. & international patents, which explicitly
cover SoundTube dispersion, enclosure &
dome technologies. SoundTube Entertainment
actively defends its patents in order to protect
SoundTube resellers and end users.

Architectural Specifications
The loudspeaker shall be an in-ground design
consisting of one 133 mm (5.25 in) low-frequency
transducer and one 25 mm (1.0 in) aluminum
dome high-frequency transducer with a fre-
quency-dividing network installed in an option-
ally sealed enclosure. The low-frequency voice
coil diameter shall be 25 mm (1.0 in).
Performance specifications of a typical pro-
duction unit shall be as follows: Usable frequency
response shall extend from 62 Hz – 22 kHz
(-10 dB). Measured sensitivity (2.83 Volt input,
1 meter) shall be at least 88.5 dB. The maximum
continuous output at 1 meter shall be 107.5 dB.
Rated power capacity of the components and
network shall be at least 60 Watts continuous
RMS power. The loudspeaker shall have a nomi-
nal impedance of 4 Ohms and be available for
25/70.7/100 Volt modes with voice coil/4 Ohm
direct. The frequency-dividing network shall
have a crossover frequency of 3.0 kHz.
The enclosure shall be constructed of a roto-
molded polyethylene plastic and have a remov-
able port plug constructed of buna-N rubber.
The grille shall be constructed of powder-coated
stainless-steel. Color options shall be granite
green or sandstone. All transducers and network
circuitry are weather resistant and ship in a
sealed enclosure.
Installation shall be by in-ground mount. The
external wiring input connector shall be hard-
wire leads. The overall cabinet dimensions shall
be no more than 358 mm (14.1 in) in diameter by
394 mm (15.51 in) in height and shall weigh no
more than 5.9 kG (13.0 lbs).
The low-frequency transducer shall have a
weatherproof butyl rubber surround to resist
weather, elements and insects. The high-fre-
quency transducer shall be a horn-loaded dome
and constructed of aluminum.
