WIRE GAUGE AND QUALITY
When using the SM516 in an 8-ohm system the total wire resistance
should be less than 10% of the speaker impedance. The SM516
speaker is nominally an 8-ohm speaker, so your total wire resistance
should be no more than 0.8 ohms.
should be less than 10% of the speaker impedance. The SM516
speaker is nominally an 8-ohm speaker, so your total wire resistance
should be no more than 0.8 ohms.
In simple terms, the extra resistance from the wire will have a very
negative affect on the sound quality of the speaker. The sound can be
less dynamic, definition of bass frequencies can be reduced, and in
extreme cases, the high frequencies can be attenuated. Amplifier
power is also wasted in the wire, reducing the maximum output level
of the system.

PAINTING THE SPEAKERS AND GRILLES
Sound Advance SM516 speakers feature a tough, weather-resistant
ABS finish that may be painted to color match your surroundings. Use
a weather resistant outdoor paint and a spray gun. First remove the
grille by carefully prying it away from the baffle. The driver
components must be protected from paint when spraying. Place the
grille on a piece of cardboard and trace around the outside of the
grille. Cut just inside the line you drew on the cardboard and place the
paint plug on the speaker baffle. Remove the paint plug when you are
finished painting.

The metal grilles may also be painted. Use very thin paint (5:1). It will
be easier to paint the grille while it is off the speaker. Avoid plugging
up the holes with excess paint.
