    Weird combination. The tweeter only operates down to 2kHz and the B139 is not good above 500Hz.

    No it is a 'real' production LS. I think it is called a 'Beaumonde'. https://www.audiovintage.fr/leforum/...ic.php?t=12411

    The Bookshelf had a simple x-over (one cap + one inductor.) https://www.radios-tv.co.uk/radford-speakers/ and https://theartofsound.net/forum/show...shelf-speakers And see Martyn Miles comment #8.

    Hi Andrew , the pair were not mine .
    I have just the one speaker that I was given by someone clearing their loft , the loft was huge and full of junk so I’m hoping the other may appear once they clear the junk .

    Cannot find the other price list at the moment, but the Bookshelf was £30 in 1966, so not going to fund your retirement just yet...
