Applications
Only 20.25” in diameter, SoundTube’s
FPS20 delivers a targeted audio footprint
for a single listener. Tight coverage,
wide-range stereo sound and a smaller
dome make the FPS20 the ideal choice
for focused audio applications, including
kiosks, P.O.P. displays, shows, plasma
displays or anywhere the visual impact
must be minimized.

Architectural Specifications
The loudspeaker shall consist of two 50
mm (2.0 in) transducers with a voice coil
diamter of 25 mm (1.0 in). Sound waves
from the transducers shall be reflected
from a 514 mm (20.25 in) Dual-Parabolic
sound dome.
Performance specifications of a typical
production unit shall be as follows: Usable
frequency response shall extend from
210 Hz - 18.7 kHz. The loudspeaker shall be
available in 8 Ohm impedance mode. Rated
power capacity of the components and network shall be at least 25 Watts RMS.
The dome shall be constructed of custom-molded PETG with an ABS driver
enclosure. The transducers shall have a
fiber cone with butyl rubber surround. The
grille shall be constructed of heat-resistant
ABS plastic material. The overall dome and
cabinet dimensions shall be no more than
514 mm (20.25 in) in diameter by 223 mm
(8.75 in) in height and weigh no more than
1.70 kG (3.75 lbs).
Installation for the FPS30 shall be
by single point hanging aircraft cable
(AC-HC20) with a 1/4 -20 stud into a
threaded insert on dome apex. Additional
accessories include Wall Mount Bracket
(AC-WB3) and Threaded Hanging Rod
