Hey!
I got new measurements taken today.
"les deux" shows the two speaker's curves, red is right. As before, the horns track pretty well, but the woofers differ. Left channel is more linear, while right shows a descending curve. both show weak output below 170 Hz.

And for those who said crossover was wrong, the other curve shows left channel with the horn polarity reversed. Easy to see the original setup was OK...

What I'd REALLY like to see is a graph of a new UPA-1A (or at least one in good shape) so I can compare with what I've got.

More listening tests today, and the region where an EQ cut is most effective is around 650Hz.

This means nothing without phase.  HIGHLY recommend along with everyone else to send off to Meyer.

As a final conclusion, this issue has been resolved by changing the two woofers. I deduct cone sag might have been the problem.
They sounf fine now.

Thanks to all for nothing.

I think you got at least your money's worth from this forum.  Sorry you're unhappy with the forum, but glad you're happy with your repaired speakers.

I think Pierre's very active participation on this board over the past 22 months since his initial thread was last posted upon indicates that he's been very happy with the knowledge here.

How about have Meyer repair just one of them?
Then you can compare a properly functioning speaker to the rest of them.

Meyer does not do reconing or offer recone kits.

They only offer new drivers.
