The LS5/9 design was created by the Engineering Department of the BBC in 1983 . The design brief was to develop a compact, broadcast quality monitor loudspeaker. The loudspeaker had to be capable of accurately reproducing the human voice, and classical music.
However, to suit the BBC’s need of minimum downtime, the speaker had to be manufactured to a very tight specification, so that in the event of field failure, the entire speaker could be replaced by another, without affecting the perceived tonal balance, an obvious prerequisite for monitoring purposes.
4 decades later, these loudspeakers are a superb example of globally enjoyed HiFi, in a historic tradition of innovation and timelessness, which we hope will give much enjoyment.
Please read through this manual. It contains much useful information to enable you to get your speakers installed correctly.
You will also find helpful advice on connecting-up, matching equipment, room placement, service and maintenance.
Provided the recommendations are followed your LS5/9’s will give you many years of pleasure.
If advice or service is required please contact the dealer from whom you purchased the product, quoting the serial number and date of purchase.
