It altered the sound balance to something i could not like. I put the old wires again, and i am happy with them as they are now.
    Mmm interesting, I will think it through, the wires inside are extremely lightweight and thin, although I have no idea what they are made of or their quality. Thanks for you advice.
    Listening is the act of aural discrimination and dissemination of sound, and accepting you get it wrong sometimes.

    So today I started on the first L100 and removed the speakers which was pretty easy. then I set down to running down the cabinets. Not too bad and with some walnut coloured wood filler I am hoping to get way with not re-veneering them.They have come up quite well, I am just waiting for the filler to firm up on the bottom corners.

    The grill cover had some well worm speaker grill material on it, which I removed and scarped the rear of the board. I am not sure whether to by some replacement foams, they are available from the USA but come in at about £300 a pair for decent ones with shipping etc. It would be nice to return them to original though. If anyone knows where to source some at a better price please let me know? I have seen ones from Poland but not sure about the quality, has anyone had any of these? I have some Royal Blue speaker material so for now will probably just recover the grills with that.

    Once I have finished rubbing down I will touch up the black paint and then use some Liberon on the cabinets.

    I'd go for the cheap Polish grilles. How bad can they be? It's only a grille in any case, £300 plus shipping is ludicrous.

    If they were designed to be listened to with the grills in situ, as would befit a domestic loudspeaker, then the grill material (an open foam in this case) might well have been part of the acoustic design. I would tread carefully with their replacement.


    I once heard the L100s many years ago in a record shop. They were suspended from the ceiling and playing 'Heroes and Villains' by the Beach Boys. Was very taken with them, to the point that I still remember the experience.

    They are domestic version of a studio monitor so fine with no grilles. Not that it makes much of a difference either way.

    OK - but they look so much better fitted with the sculptured foam 'waffle iron' grille. I would choose the brown grille, so it looked like a giant chocolate bar!

    Yes, the orange grille looks good.

    .
    In a thousand years time scholars will still conclude that if you were going to be stuck anywhere in time then the 1970s would be the optimal choice.
