Please double check the original matches the product images AND voice coil size before ordering. This diaphragm WILL NOT FIT some of the very early SRM-450 loudspeakers which were not fitted with spring clip terminals.

PLEASE NOTE: Mackie routinely change driver specifications during manufacture of any given model of loudspeaker. As a result, more than one type of compression driver may be fitted to any given speaker model. We strongly recommend NOT sourcing your replacement compression driver based solely on the Mackie cabinet model number, but by removing the compression driver and determining the part number for that. This will then enable you to accurately select the correct replacement diaphragm for your speaker.

Our database of parts includes a wide range of products, and in many cases offers cost effective alternatives for repair. Alternatives are loosely grouped into three types:

Original - Usually an exact match to the original product, and just the 'standard' part from the factory which gets rebadged by manufacturer with their own brand and part number. Occasionally, there are subtle tweaks made from the standard part, but its virtually impossible for us to determine this. If we have listed the part as Original, it means we are confident the performance is the same.
Aftermarket - Aftermarket parts often become available from factories in the far east once the original part is no longer manufactured. They are intended to be a close match, and provide a cost-effective alternative.
Equivalent - These are alternative options, which provide very similar performance, but are not the same as the original. In some cases the performance may actually be improved. We have used both our own experience, and feedback from customers in generating list of alternatives. Alternatives like this are useful when the original part is no longer made, there is no aftermarket option, so the only choice is to upgrade with the nearest current equivalent product.
