carefully. Keep it in a safe place for future reference.
• Install the speakers in a cool, dry, clean place – away
from windows, heat sources, sources of excessive
vibration, dust, moisture and cold. Avoid sources of
humming (transformers, motors). To prevent fire or
electrical shock, do not expose the speakers to rain or
water.

A vessel with water in it

amplifier to be driven into “clipping”. Otherwise the
speakers may be damaged.
• When using an amplifier with a rated output power
higher than the nominal input power of the speakers,
care should be taken never to exceed the speakers’
maximum input.

Taking care of the speaker
To maintain the spotless glossy surface of the
polished finish, wipe it with a soft, dry cloth. To
avoid damage to the finish, do not apply chemical
solvents, such as alcohol, benzine, thinner,
insecticide, etc. Also, do not use a damp cloth, or
any type of cloth that contains chemical solvents, or
place a plastic or vinyl sheet on top of the speaker.
Otherwise, the finish may peel, the color may fade,
or the sheet may stick to the surface.
