That sounds like the amp board died. Mackie parts can be hard to source, and Mackie is really slow to ship, so I suggest taking it to a Mackie authorized service center. Here's a link-

Sounds like a problem with the horn amp in that cabinet. This is not a user fixable problem and needs to go to the shop. Here is a link to the Mackie support page where you can find a link to the repair shop list.

Yes, that's how they're made: cable cut to length, connectors attached, tested, packaged and shipped.

replace diodes D106 and D107

Consider having it reconed... usually costs half of new speaker. Search google for "speaker repair" such as

The amp is likely blown. This is not DIY unless you are competent at electronics.

This MAY be very close to your system... there are several parts to the schematic in this compressed file...

OFTEN companies do NOT re-engineer things so one has to use intution as to what the model number thisng might be listed...

You often find modules are identical between units even though the model is labelled differentely.

No. It should not cut out. Must be a circuit problem. Get in touch with the shop you bought it from or a really good repairer and get them to have a professional look at it but get a quote first.
Good Luck
