Any potential problems with poping off the metal speaker grilles of my Kef 2005's and spraying them to match the speaker unit? Has anyone tried it? My living room's quite pale, and the black grilles do tend stand out somewhat. I thought a few thin coats of spray paint could make them a little more subtle. Does any know if the front grilles can be taken off without dismantling the speaker (which I don't want to do). From the 2005's info page on the kef web site, it looks like they push on from the outside. They do seem quite well fixed in though. Thanks, Balders.
