Treble 20
the single loudspeaker faces downwards onto two cone reflectors, the upper reflector having a central hole and being for the sound from the outer part of the loudspeaker cone, and the lower being for the sound from the voice-coil dome and inner part of the cone. When this loudspeaker unit is stood on a flat sound-reflecting surface, this surface acts to some extent as an extension of the lower cone reflector. This unit gives a uniform horizontal distribution of sound.
