It is sad that MV is going - but I am pleased it will still be studios, in all likelihood. So many BBC buildings are gone. I worked in TV film to begin with at Ealing, and various Shepherds Bush buildings, then Pebble Mill. Then moved to radio and had to do the rounds of all the London buildings. Many of those buildings gone.

theseThere is a lot of misinformation about the use of Ls3/5a. As the development documents will show, they were intended for use in TV OB trucks, where space is very tight. Fine for use on speech and of course in mono back in those days of circa 1975. Then the hifi market started selling them and claiming they were used for music recording etc, which was hardly ever the case, except rare small set ups. Never a big orchestra. They were ok on speech. Nowadays I have seen them used os talkback speakers, as they are great for voices and low grade monitoring. The Radio OB trucks back then had much larger LS3/1, then LS3/7 and then LS5/8. Nowadays they have the same Geithain monitors that are in MV1, or Genelec. There are some great shots of the Radio OB fleet
