Re: I HAVE THE MTX TP112 SPEAKER, THE HORN TWEETER...
It is a one piece horn need to replace the whole thing. These are not like normal PA speakers where the driver can be unscrewed from the horn lens and replaced.

You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.
The typical cause of this is a blown tweeter or the tweeter has broken off of the horn and fallen inside the cabinet. Remove the screws from the horn and carefully remove the assembly. Try the speaker at low volumes to see if you hear any sound at all. Next, remove one of the wires and using a 9Volt battery quickly touch the 2 leads on the tweeter. If you don't hear a click, the tweeter needs to be replaced. Contact Mackie service for a replacement.
If you hear a click, then the problem is in the crossover or amp and further investigation willbe required.
yes, but it is attached to circuitry that allows only the high frequecies into it. You can replace the speaker with any 8 ohm tweeter without any difficulty, but if there is a capacitor across or in series with the speaker, make sure you put it on you new speaker the same way.
The most common cause of this is a blown horn. A replacement can be ordered from Mackie directly. Remove the screws that hold the plastic horn in place. At the rear of this part will be the tweeter assembly that unscrews from the horn. This needs to be replaced.
Another possibility is that the tweeter driver has broken from the horn itself and is inside the cabinet. Remove the horn and you may find that the aluminum part has broken. Replace the horn which comes with that part and you should be fine.
You need to get another amp for your sub. I would say if you want good quality go for MTX because I have had amps from MTX and never had a problem. what you need to know is look at the fuses on the amp if there are 3 of the 25 amp fuses on there then it should push out about 750 watts but on MTX they under clock the amp so it will push about 800 at 14.4 volts for that you will need a 4 gauge wiring kit with a 60 amp fuse in the fuse link. As far as your other amp hook up the speakers and tweeters to that but be sure to tune in down and you would need a 8 gauge wiring kit. I hope this helps you.
