Question about Mackie SRM-450 System
A new diaphragm can be fitted into the original driver and the speaker will be like brand new. first you must determine if you have the older RCF version (M44TI) or the newer Mackie versions (0008093). There is only one RCF diaphragm that will work for this repair and they are scarce. There are both authentic and aftermarket Mackie diaphragm options and both work very well.
