Hi all,

I've just inherited a Quad 33/303 amplifier and would like to build a pair of BBC LS3/5a type speakers to experience the sound of the early 1970s (when I was a lad!) Can anyone recommend plans for such a build? I want to spend as little as possible but still be authentic. I am based in the UK so shipping anything from the US is too costly.

I saw this article which at least provides information about the crossover and some basic dimensions. There are a few references on diyaudio and hifiwigwam on the ls3. Eg ... nes-3.html. I had the b110 and t27 in my kef concerto kit from that period. Lovely sound. My hearing was better then. Your own falcon acoustics seems to have most of the parts but looking pricey these days.
