Mackie srm 450v2 tweeters sound low

You have to disassemble the cabinet with a 18 inch long screwdriver first in order to get access to the driver, then remove the 4 allen nuts on the plastic that covers the diaphragm and proceed to change the diaphragm, most of times they start to sound low because they break the titanium in peaces or in a small portion.

Tweeter problem

Since this is a bi-amplified speaker there's only 2 possibilities here:

*Tweeter amp or,
*Tweeter diaphragm.
You can test the diaphragm as a starting point using an ohmmeter to verify tweeter coil impedance, let me know if i can help more.

How to open a Mackie SRM450

Sorry about the late response. These units are sealed at the factory and opening them up for the first time is a bit of work. Make sure that all the screws are out of the unit and using a large screwdriver, carefully pry up one side. It will be difficult. Apply steady pressure and the back will eventually free up.

Mackie SRM-450 tweeter distorts sound

I'd just order a new diaphragm and see if that's the problem before any other dismantling. If that's not the problem, I'd take it to a certified repair shop. The fact that it's still working but not producing certain frqs,tells me you won't be able to see the problem with the naked eye.

Repair a Mackie SRM 450 Speaker The Speaker is making a crackling sound while playing. The sound keeps cracking up.

You probably need to replace the diaphragm. The diaphragm is located behind the back cap. Simply remove the back cap, remove the diaphragm, clean the voice coil gap with a piece of masking tape, install a new replacement diaphragm, reinstall the back cap. That it!
You can see videos on how to replace diaphragm at this link.
You can buy a new Mackie SRM450 diaphragm at this link.

How to change the hf unit?

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.
