I've got an old Schroeder 1210 with a distortion problem, and Jorg said to remover the tweeter. I've done so, but, do I need to now join the two wires that were attached to it so the circuit is complete?
I'm now getting no noise or sound at all, the ex-tweeter connections are hanging in air now...

Mr Smiley Face is where the tweeter was.

Ex-tweeter connections.

I know, it's a dumb question. 🙂

Why not repair it properly?

Some crossovers can crate issues for class D power amps when the tweeter is removed or fail open circuit. Generally the protect light will turn on at the amp,but not always because it's a non-monitored fault condition.

I've put it back- for reasons I might not be aware of, like that one, for instance! 😃
I don't know what's up but this particular cab is having a low-level distortion issue. I'm talking with the guy I got it from and we're having a civil and agreeable conversation about it.
This small problem has become a focus for me and I just can't fit it into my cart, as it were. I'm taking some time to decide if I should hand it back to him or take it to be professionally assessed.
This post is part of a not so long string of inquiries/emails, etc. to ascertain what in the heck I should do to get my small gig scene functioning now that I'm halfway across the stream with this process...

Ok, now we are getting down to the root cause of the problems.

This is a good example of why amps/cabinets that have been modified or messed with cost more to fix properly, it takes a lot more time and effort to figure out all of the ways possible to screw something up. End users and hack techs can be unbelievably "creative" in this regard.

A little knowledge is a dangerous thing.
I don't know the ramifications of that crossover mod, what they might be. But I played through it again tonight and it's more distorted. Seems like I may be headed for a recone job. We'll see, I'll make sure I've got that sussed first.
I'll end up having effectively paid again the price I bought it for to repair the damage from a shade tree speaker designer. Lol, serves me right for going cheap! But hey, it was a Schroeder.

I suggest that you stop messing with it before you possibly damage your amp... no way to know what you have at this point but it's not working correctly.

Update... I've found that the 10" driver from the Schroeder 1210 is distorting, so I'm bringing it to a tech I know locally for a re-cone. Also the crossover is not the original, so I'm removing it and the horn for now. I'll see if I replace it with one from Schroeder, I'll use it without until I think I need one back in there.

I was incorrect, it turns out the crossover is the right one... 🤓

So I took the Schroeder cab to a gig last night. Several days ago I brought the speaker to an accomplished and well-known tech in the neighborhood. He put the speaker on a tester thingy and worked it pretty good, no issues. It was fine. Lol. I don't know what to say.
Still, two days ago I still heard a light rattle when I played through it. But, it hasn't gotten worse- that is meaningful since it tells me that there's no damage to a moving part or I'd be hearing it get worse... I'm not going to belabor it any more.
Anyway I played it with the Mesa for three sets last night, and it was fine. Nothing but what you'd expect from a good bass rig. Now I'm at a place where I can just pay attention to getting this little system dialed in.
I'm done stressing now.
It's weird, I guess, but I'm walking on the sunny side of the street.
Thanks everyone, for your participation, help, and wisdom.
The Hartke combo was there just in case...

So this isn't over, I plugged into the cab last night and there is some kind of rattle in it. I can't find anything loose in the structure of the box, I don't know what to think. Maybe it's the horn. And oh yeah, as I put all this down it occurs to me that I did consider a wire laying against the frame of a speaker. I'll look into that later tonight. I would love for this to come to a happy end!

Sometimes structural failures aren't visible. Rotate the cab 90 degrees and see if the noise persists. Then try 180 degrees. Then 270. You can also try placing something heavy on top of the cab and see if it helps.

If the noise can't be heard while the band's playing, then you have the option of just living with it.

EDIT: I just noticed the Hartke is laughing at the Schroeder.

I had a Schro 1210 cab like that for one gigging season, most schizo cab ever. It worked great in the one legit rock club in town though, at least. And yeah, be sure all internal wiring is battened down completely, and maybe try a nice Pfriem Pilsner or a Black Butte Porter instead of that skunk carp, the Pilsner will be easier to clean up when it takes a dump... ;)

I can't play it without being bugged, and I need to play it to get everything else dialed in- like the new-to-me Mesa TT-800 and a Fender Jazz Bass.
I've bundled the wiring to keep it away from the speaker magnet, had the speaker I suspected tested thoroughly, now I want to bypass the crossover...
I an hoping to like this cab, but it's losing me...
