Hi There, This is quite a common problem with the Mackie SRM450's. You will find that you need to replace the diaphram on the top. This can be done by removing the 16 screws from the back of the Mackie (quite a long pain in the **** job) with a long handled cross head screw driver.
Once you have done this you should then remove the hex bolts from the back of the drive where the black and right terminals are. When this is done, pull off the cover and swap the diaphram out. With the new diaphram in place reverse the steps above but before you screw the back on, power it up carefully and check the sound is now working.
If the diaphram keeps going eg every 3 to 4 months then you will need to change the driver which is quite expensive to do. If you need spares and are based in the UK, contact LondonSpeakerShop.com who carry spare parts or can undertake the repair.
Hope this helps.
