They are never seen, only heard
Since 2007, the Sentosa Express has connected the Singaporean island of Sentosa with the mainland. The train station in the continental region of HarbourFront is equipped with two LFI-220 line source speakers with Fohhn Beam Steering Technology and four active XS-30 subwoofers.
The speakers serve as the sound system for a large screen in the main train station concourse. Various tricks were used to make them unnoticeable: the subwoofers are hidden behind the screen’s panelling and the line source speakers were made in a custom colour from Fohhn’s in-house paint shop that perfectly matches the video projection screen. They are now in Sentosa Orange.
We would like to congratulate everybody involved in this successful installation!
