Yes the old LS3/5A are repeatable. I one heard a very early Rogers one
and another make can't remember who's it was now apart from 11 ohm
impedance the imaging was excellent. OK so they don't do real bass then
don't go loud but for OB vans their intended use they were fine.

Course that design is some, what, 50 ish years old now and as mentioned
BBC born and bred they nowadays don't do that much of that anymore but
they used to design and make a lot of gear years ago radio and TV.

I once worked for Pye TVT, Neve and Audix it was well known sell to the
BBC and you could sell to anyone any broadcaster even the Germans where
engineering is still a highly regarded profession.

So what else is wrong then and who are considered better candidates for
that job and why Trevor?..
