Diagnosing why previous owner cut internal tweeter wire CSi5

I bought a used CSi5 and noticed the sound was muffled and terrible. I opened up the speaker and found that the wire from the crossover board to the tweeter was cut, and instead the tweeter was wired to one of the main drivers in parallel.
I reconnected the tweeter to the tweeter output from the board and the sound is unchanged and I think I’m not getting any sound from the tweeter (pretty sure I wasn’t before either, when it was wired to the main driver).
The tweeter’s resistance is measuring at 3.8ish ohms.
The crossover board doesn’t otherwise appear to have damaged components on it.
So all that is to say, what should I do next? Why would someone have cut the tweeter wires and wire the tweeter to the main driver? If the original problem was the crossover, did their attempt at a “repair” toast the tweeter too?
Pictures attached, I hope someone can help me.

A real electronics genius evidently.
You have one of two choices if the crossover tweeter section works.
Get new wire remove the old from the xo and solder new to where it went.
Get two but t connectors strip and reconnect the sections of wire.

Tweeter is definitely fried if it was running with the mids lol
Most likely the crossover fried so he thought wiring the teeter to the mids would help lol- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
Woohooo! Thanks for your help and I put everyone. Luckily I was able to fix everything with a $.5 resistor! Before ordering anything I took readings on the resistors and R1 wasn’t showing anything (the 5W 2 ohm one) so on the off chance that that was the problem I barbarically ripped off the old one and soldered on a replacement and now I have good sound!
I’m amazed the tweeter wasn’t blown, I had a feeling it possibly could be working since it was showing a resistance reading remarcher than zero. -
I hate hacks. The people, I mean. Mostly for the destruction they wreak. And they do probably reek, too.
Good job tracking it down properly, and fixing it.I disabled signatures. -
Glad to hear you have found the issue!
