the box Diaphragm 4401

Its very simple to change the diaphragm on the Thomann Box range of speakers. Just undo the 4 alum keys holding the horn in place, remove the next 4 alum keys holding the diaphragm in place - remove the old one and gently insert the new one. Replace the alum keys and job done!

As mentioned in the heading they also fit Mackie SR450 mk 1 not sure if they have changed the HF unit for later models.

Reasonable price and easy to install,not a major problem when one occasionally blows.

very easy to install, well packed, and best price you can find

Cheap cheerful, very easy replacement for the inevitable.
