Matching pair of LS5/1 studio monitor loudspeakers with AM8/1 amplifiers, c.1966.

Used by the BBC to judge the quality of the audio in its radio and television programmes. Studio versions of the LS3/1, designed to replace the LSU/10. The cabinets were larger than the LS3/1 and the tweeters were mounted above the woofer, rather than in front. This pair uses Goodmans 380mm (15") low frequency drivers, plus two GEC high frequency units. Each one has a plinth below with a 'built-in' AM8/1 amplifier.
