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.
For theft deterrence, all XT550 speakers come
with anti-theft brackets and square-tip screws.
The system shall be the XT550 for both low
and high impedance applications.
