SERVICING

Cabinet finish.

To remove marks and scuffs use a medium soft brush. If necessary, a little warm water and detergent can be used but under no circumstances use a solvent or abrasive cleaner. The surface will change colour when wet but will return to normal when dry. For touch-up of paint chips contact your local Tannoy service agent for materials and guidance.

Dual Concentric driver removal.

Lay the cabinet on its back. Remove the six hexagonal bolts and set aside. Ease the driver from the front of the cabinet taking care not to mark the front surface.

Use a piece of stout cardboard to lever against if necessary. Remove the driver, note the polarity of the internal connections and disconnect the internal wiring. Take care not to damage the moving parts of the LF driver.

To refit the driver, connect the cables from the crossover to the LF and HF terminals.

Fit the driver into mounting hole, making sure that the internal connecting cables are not trapped between the HF unit and the cabinet crossbrace. Fasten the bolts finger tight and then progressively torque them down.

Drive unit servicing.

The HF unit may be fitted with a new diaphragm assembly or replaced as a complete assembly for speed. In either case, with the driver face down, release the three bolts securing the HF assembly and lift the HF unit vertically upwards and away from magnetic attraction caused by the LF magnet. Replace the diaphragm - it is self- centring - or the complete unit, taking care to align the parts correctly.

To refit the HF unit, hold it about 300 mm vertically above the LF magnet in both hands while resting on your elbows. Slide your elbows apart and lower the HF unit onto the back of the LF magnet. As the HF unit gets close to the magnet you will feel the magnetic fields repelling. Align the fixing holes and secure with the bolts, tightening down evenly. Do not tighten the bolts finally until you are sure the HF unit is seated correctly and the two magnet systems appear parallel.

The LF unit may be re-coned in the normal way. Ease the trim ring from the rubber surround and remember to refit it. The trim ring forms an integral part of the HF dispersion system. Use only the parts and adhesive supplied in the re-cone kit.

Crossover.

The crossover is mounted on the rear of the terminal panel. To inspect it, remove the panel by releasing the hexagonal screws. Take care to avoid undue stress on the cables and components.

To remove the crossover completely the cables must be disconnected from the drive unit. Please proceed as above to remove the drive unit.

Checking the unit.

The speaker can be checked using a sine wave generator. A high quality, low distortion (preferably a beat frequency) oscillator will be required to check for any buzz and rattle noise generated by the drive unit. The voltage to be applied at the speaker terminals should be about 3V rms (the speakers should be free from buzz and rattle at any audio frequency).
