    Many thanks to the information in this great forum I had a few Hartields build. Therefore, once again many thanks to all who made this forum possible.
    More images.

    Regards
    Juergen

    Ps Please do not look at the lens, I work because they have to gold anodize.

    Juergen,

    congratulations! It is a very fine work.
    You have let us share your progress within your avatar already, now it has come to a "golden" end.

    Your pose scares me. The lady must be very old, so it is a no-no choice. :shock:

    Please let us know not only your listening impressions but some measurements too - as far as I know you have the original speaker package.
    ___________

    Rich, Peter,

    Thank you for your comments.
    I have not quite the original speaker. The 150-4C, I have only to the 32 ohm version, 150-4. Therefore, I can not use the orginal crossover. I will, therefore, only an active crossover and use triamping. According to the findings, I will then build a passive crossover.

    regards
    juergen

    Powder coat !

    Jurgen,

    it would'nt cost much to have the lens powder coated .

    And, I think you are much prettier than the original

    Beautiful! A piece of history made new. I envier you these beautiful speakers.

    Question: How do they sound? Please try to give me (us) a listening test.
    It's really all about music.

    Rich,
    I will also make DIY anodising, it is cheaper than powder-coated. But it is very difficult to remove original color.
