Visitors walking past the RSF stand at ISE 2010 couldn't help but hear a female voice whispering 'Pssst… over here' in their ear. The sound came from the company's latest directional loudspeaker, the SpotDAP.

The SpotDAP boasts a 3° directionality and an intelligible sound projection distance of up to 20m. Billed as an "extreme directivity loudspeaker", the SpotDAP is available in two models": the SpotDAP450 (black or white) with all region power supply; and the SpotDAP460 (black) with all region power supply and providing approximately double the SPL of the SpotDAP450.

The company also debuted a new module that adds bass to the units, allowing them to project music as well at the unwary.
