Description
The SoundTube XT850 is a premium
2-way outdoor loudspeaker solution for
installations requiring high-performance
sound in a durable speaker design. The
XT850 is designed for full-range back-
ground/foreground music and paging.
The sealed, in-ground enclosure design
delivers true low end response (59 Hz,
- 10 dB) and optimal off axis performance.
The XT850 includes theft-resistant mounting
hardware and a weather-proof 5-position
tap switch for 25/70.7/100 Volt applications
with voice coil direct (4 Ohm) position

Applications
The ultra-wide 360˚ horizontal dispersion
pattern makes the XT850 an ideal choice for
theme parks, promenades, playgrounds,
shopping malls, restaurants, resorts, gar-
dens and other outdoor applications. XT850
speakers come with in-ground anti-theft
brackets and stainless-steel square-tip
screws for increased outdoor security.

Preliminary Technical Information for System Engineers
Architectural Specifications
Mechanical Drawings
The loudspeaker shall be of in-ground
design consisting of one 203 mm (8.0 in) low-
frequency transducer and one 25 mm (1.0 in)
aluminum dome high-frequency transducer
with a frequency-dividing network installed
in a sealed enclosure. The low-frequency voice
coil diameter shall be 32 mm (1.26 in).
417 mm
(16.42 in)
338 mm
(13.31 in)
Performance specifications of a typical
production unit shall be as follows: Usable
frequency response shall extend from 59
Hz – 22 kHz (-10 dB). Measured sensitivity
(2.83 Volt input, 1 meter) shall be at least 90
dB. The maximum continuous output at 1
meter shall be 112 dB. Rated power capacity
of the components and network shall be at
least 100 Watts continuous RMS power. The
loudspeaker shall have a nominal 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.
360 mm (14.7 in)
79 mm
(3.11 in)
Included Accessory
The enclosure shall be constructed of a
roto-molded polyethylene plastic. The grille
shall be constructed of powder coated stain-
less steel. Color options shall be granite green
or sandstone. All transducers and network
circuitry are weather resistant and housed in
a sealed enclosure.
Installation shall be by in-ground mount.
The external wiring input connector shall be
hardwire leads. The overall cabinet dimen-
sions shall be no more than 360 mm (14.7 in)
in diameter by 417 mm (16.42 in) in height and
shall weigh no more than 7.5 kG (16.7 lbs).
