Very rare floor standing speakers from German Physiks in very good condition. These look like something from a science fiction movie but perform like a Formula 1 car. The built quality is exceptional. These loudspeakers, produce a very accurate and realistic stereo image. Another key advantage of the DDD driver is that it is omni directional, so these excellent stereo images can be enjoyed from a wide range of listening positions, unlike conventional designs which have much smaller “sweet spots” due to the tendency of their drivers to beam the sound. This is an ideal property in a loudspeaker that may be used in a home theatre system where there could be many listeners.
