Just follow these easy Replacement Diaphragm steps!
Great care must be taken when replacing a diaphragm, so take your time and do it right!
Start by removing the scews that secure the diaphragm housing to the magnet. These are usually located on the front side of the magnet assembly.
Carefully lift off the housing assembly. Clean and inspect the voice coil gap. Remove all foreign material and make sure it is uniform in shape. Most diaphragms fail because of too much power, distortion, or too low of a cross-over point.
Test fit the new diaphragm into the housing. See how it lines up and make sure that you have the right part. DO NOT FORCE IT! It should fit perfectly.
Align the diaphragm into the housing and re-install the screws. DO NOT OVER-TIGHTEN. Too much torque can warp the diaphragm and damage the driver.
Carefully align the voice coil into the magnet slot. It should fit perfectly and slide in without any friction.
Line up the holes and tighten the screws firmly but do not over tighten. Sweep test (generate a wide range of frequencies) the driver after connecting it back into the speaker cabinet and connecting it to it's horn or lens. Listen for buzzes or rattles as this is a sign of incorrect installation or other damage.
That's it! Your HF driver should be as good as new! If you need any advice or other info about replacement diaphragms, e-mail us or give us a call at 1.847.963.0733.
