Installation and cabinet guidance
Allow for a 146 mm panel opening and a 155 mm fixing circle, with space behind the speaker for the magnet and connections. TR 10.16 and TR 6.8 transformers fit the mounting arrangement and are separate components.
Use an amplifier suitable for the 8 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.
