Driver replacement procedure
If it is necessary to replace the bass driver, place the cabinet on its rear and, using a 4 mm
hex head driver, remove all of the bolts. As with most objects held by a series of bolts, these
bolts should initially be loosened a little, one at a time rather than each bolt being fully
removed whilst the other bolts remain fully tightened. When replacing the bass driver, the
gasket behind the driver should be replaced with the new gasket that will be supplied with
your new driver.
Tweeter replacement procedure
The tweeter is secured by 4 x M4 machine screws. Remove these with a 2.5mm hex drive.
Take out the tweeter and disconnect the two wires, noting which colour goes to which
terminal. If on removing the 4 screws that hold the tweeter there is any difficulty in removing
the unit, do not try to force a blade between the cabinet and tweeter, but use a small narrow
bladed screwdriver in one of the screw holes to gently lever out the tweeter. If it is necessary to
replace the diaphragm:
a) Remove the 3 pozi screws on the front plate of the tweeter using a number 1 pozi driver.
b) Remove diaphragm assembly and replace with the new diaphragm. The ferrofluid has the
appearance of oil and is dark brown in colour and should cover about 1/3 of the coil. If
there is less than this then additional Ferrofluid should be added (generally the fluid will
only need to be added after you have changed the diaphram 2 or 3 times). This can be
obtained from your dealer/distributor or directly from Quested. It should be noted that
ferrofluid is best added as shown in the diagram below and not from the syringe that it is
dispensed in. The fluid should never cover more than 1/2 the coil.
