• Selectable taps — The rotary tap selector switch, located behind the grille, sets the
speaker to operate in either 8-ohm direct or 70 volt /100 volt operation with 16, 8, 4, 2,
and 1 watt taps.
• Magnetic grille — Magnets spaced around the grille edge enable it to be easily
attached and to remain firmly in place.
