Abstract
For more than a quarter of a century the normal broadcast receiver has been equipped with a single loudspeaker fitted inside the cabinet. The introduction of sets with two separate speakers, each reproducing part of the frequency spectrum on the Philips "Bi-Ampli" principle, dates only from the last few years. The installation described goes a big step further, the loudspeakers berg entirely separated from the amplifying part; two low-note speakers are housed together in a special cabinet and two high-note speakers separately in their own boxes. The quality of reproduction has been remarkably improved in this way, which appears to full advantage with fm reception and the playback of gramophone records or tape recordings.
