I have sixty of these drivers, if you need (backup) drivers I can make alterations to my build to accommodate different drivers, since I have not done much the last few months. They are still in the boxes and haven't even been tested. Let me know if I can help.
That's a very kind offer. I'll let everything sink in for a while and figure out what to do.
Like ra7 I had thought I had bought drivers that would last me forever!

Too bad the SB10PGC21-4 has a distortion peak around 4kHz, because on paper, it looked like a real candidate for LAs.
Maybe using 25 of them would tame that distortion peak.

Usually things get exaggerated or magnified when used in a line...
The 10F (8414G10) is better behaved in the top end, but slightly worse (in distortion) than the TC9 on the bottom end. Quite an upgrade in price level though. It seems it's the new TG9 of Scan Speak, while the others like the 10F 8424G00 are meant to be mid-ranges. As seen by it's closed area below the spider.
I could seriously consider going with the 10F. As this kind of is my all out attempt at an ultimate full range line array...

that would be a crazy price to pay when you need 50 of them
trouble is there is nothing near as good as TC9 in same price range
then there are issues of fitting on your baffle
Seems the TC9s were reliable until left in garage long term. I would replace them, then hope not to have to store them again. Perhaps drivers from fresh lot will do better...
Yes, I understand.
But doesn't distortion decline when using multiples?
I have only 2 left at the moment. I had 4 previously.
I should've done a test 1 vs 4 to see if that 4kHz distortion peak stayed the same, got smaller, or bigger!
Hello Ronald,
You should get in touch with the supplier. This looks like a matter of inherent driver failure, not a matter of driver abuse. This has nothing to do with burnt vc's or so..
Any buyer is entitled to a decently functioning product, not one that simply falls apart after a certain period of regular use.

Not an easy job. The connection of lead wires to voice coil is hidden under the dust-cap.
That sure is true...
I won't disagree with that...
Did they respond well to EQ?
I don't know how valid such a claim would be after 9.5 years have passed, even though I expected them to last way longer. In the thread on a couple of drivers models from Scan Speak, they weren't quick to do anything about it. But it can't hurt to try.
Your measurements showed a 4k distorsion peak - was this also measured/verified by others?

If I would ever go for the Scan Speak 10F it would be partly driver by curiosity.
I've always been satisfied with the TC9 and have never doubted it's performance.
If we look at distortion profiles, the TC9 does quite well even at higher volume. This made it a save bet as choice for this application.
The 10F seems like a more expensive sibling, but clearly it is Scan Speak's replacement for al kind of specialized uses that they used to have with the TC9/TG9 pair when they still owned Peerless/Vifa.
What I do see is that the distortion profile is different in the 10f when compared to the TC9.
While the TC9 certainly is clean, the 10F features H2 clearly above H3 'everywhere' while in the TC9 they are closer together and even alternate which one is the higher of the 2 profiles.
The frequency curve seems a bit flatter too on the 10F. Leaning even more towards textbook behavior.
Which one is the better use of materials is a really tough one due to the price differences. 😉

Yes, they do.
I have them playing in my DIY camper in little sealed boxes (assisted by a sub) with some gentle EQ to account for the small space.
After having had time to think about this, I feel as though the failures are not "that bad". As you said, it's been almost 10 years - and these are cheap drivers (in the monetary sense of the word). The question remains; how problematic will it prove to get replacements in the future, and will those replacement be interchangeable with the batches we have?
Maybe its time for a second opinion on the SB 3"er... I have to search some more...
Would they be a slot-in replacement mechanically for you wesayso?

I second the second opinion! 😉
I would love if someone can prove my setup had problems.
I still have a pair. I should redo some measurements.
The SB10 is a little smaller than the TC9. It would not be a straight drop into existing holes.
I don't know if the 10F is the same as the TC9.

10F would be a drop in fit, if it would have had a square basket/frame. So it would have to be adjusted to fit(!)
