KEF 103.2
These are very nice large bookshelf/small floor standers (with a stand preferably?) They have a very interesting crossover that has active semiconductors and so draws power from the music input to operate the electronics (there is no separate power supply and they are not "active" speakers, no amplifier built in. The electronics operate the protection circuit and a LED for over drive indication? There are a couple of capacitors on the crossover board that leak and need replacing, these are part of the protection circuit. Sometimes the leaky caps corrode the copper track and make the drivers appear dead. The active protection electronics are in the two red upright "slabs"; they are dip coated in a varnish or epoxy.
