    Hi Ben,

    I don't know if you've seen Ken's website so here are some links:

    http://www.jkwynn.co.uk/

    http://www.jkwynn.co.uk/66_HTML/66_Thumbs.html

    http://www.jkwynn.co.uk/Project_Images/66/66_XOver.pdf

    The last link has a parts list and a very nice diagram.


    Here is a link, to our own "Knowledge Cafe" for the Ditton 44 circuit diagram and parts list:

    https://theartofsound.net/forum/show...er-Information


    You'll see there are some differences.

    Tweeter (Ditton 44 - C1, C2, C3, C4 / Ken's 66 - C5, C6), disregard the 44 circuit and follow Ken's work. It's only a matter of getting the correct value e.g. Ditton 44 C1 + C2 (4.7 + 1.5 = 6.2) Ken's 66 C6 = 6.2. Ken's approach is arguably better and it's definitely cheaper.

    Midrange The only difference here is a change in value (Ditton 44 - C5 = 6 / Ken's 66 C3 = 4) for this, stick with the Ditton 44 https://www.falconacoustics.co.uk/al...le-series.html


    Other than that, follow Ken's work, that's all I did!

    As for Quad 405's. If you click the link in my signature it will take you to my Gallery. On the first page there's a link to what I did with them, best of all the photo's were uploaded here, not PhotoFuckIt so they're still visible! Other than that I can't be of any more help I'm afraid, read through the thread and you'll soon realise I'm not even at novice level

    I do hope this gives you the information and confidence to get this started, if not just keep asking questions till you get it

    Apologies for the late reply. I hadn't seen Ken's website, thank you for the links. Really good read.

    In all honesty that makes absolutely no sense to me at all Any chance of really boiling that down to basics? Is that what you follow if putting the 66 mids into the 44's as you have done?

    I have been given this list for the 44's which I will post up below for future searches.

    Alcap;

    4x72uF/100v*
    2x30uF/100V*
    2x6uF/50v*

    Ansar:

    2x3.9uF*
    2x6.8uF*

    The only reason the top two are 100V is they dont do em in 50V..
