Installation and cabinet guidance

Allow for a 146 × 87 mm oval panel opening and align all four fixing positions. Consider the speaker’s orientation when planning coverage, as horizontal and vertical dispersion differ. Optional grilles: 4645 and 4745.

Use an amplifier suitable for the 4 Ω load and observe terminal polarity. For a 100 V line system, connect through a suitable line transformer; do not connect the driver directly to the line.
