The grille and frame of the speakers may be easily painted to match your
décor. It is best to paint the frame and grille separately. Remove the speaker
grille and use the paint mask (the center section from the cutout template)
to protect the drivers and baffle. Paint the grille separately and let it dry
completely before reinstalling it.
Painting
The HD series speakers can be safely used with any receiver rated above
20 watts per channel. There is little advantage in using more power than 100
watts per speaker, but receivers above this power rating can be used so long
as the receiver is not operated at distorted levels.
To protect the tweeter, a self-resetting circuit breaker is incorporated into the
crossover network. If the speaker is overpowered for an extended period,
this circuit breaker will open and the tweeter will be disconnected. When
the volume is reduced or the overload has passed, the circuit will reset and
normal operation will be restored.

The speaker grilles and exposed rim can be cleaned with a soft, damp cloth
or mild cleaner.
Brush or vacuum the grille panels with a soft brush attachment to your
vacuum cleaner.
Enclosure Cleaning
Operating a receiver (of any power rating) beyond its maximum undistorted
output level creates distortion – added high frequency sound not part of the
musical program. Distortion dramatically increases the internal operating
temperature of a speaker and will eventually cause the speaker’s failure due
to burned or melted internal parts. While Cambridge SoundWorks includes
the most heat-tolerant parts commensurate with good acoustic design, the
speaker’s Limited Warranty against defects in materials or workmanship does
not apply to parts that fail from long-term operation at very high temperatures.
