Appplications
8 Ohm (nominal value)
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.
