    Agreed!

    And how did you make the diffusers? I recognise the metalwork as possibly being protective grills taken from an electric fan, but the cones elude me.

    Anyway, a lovely job - well done!

    I made the diffusers by securing a long wood screw into the centre of the panel and moulded plaster around it to the approximate profile. Then using a profile template as a guide, sanded it into shape. The board was painted with PVA and the plaster applied while it was still wet. PVA was also mixed in with the plaster. The shaped plaster was impregnated with wood hardener to seal it and then sprayed white with matt acrylic paint.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    That's what they are (computer parts) and they don't 'ring', there's a rubber damper on top.

    Before anyone asks. The cabinets are vinyl wrapped. It worked a treat!

    Old school! I was wondering if you'd used a 3D printer.

    That would cost me £300, not the three quid I spent!

    Nice looking speakers.

    Do you still have some Tannoy's hanging around? I fondly remember the cheviots you had many years ago.

    No Shane. The Tannoys were lovely, but too big for my current environment.
