Grundig Box

Hi Dear Massimo,
I would like to ask beforehand how you and your family are doing.
My question is about the Grundig Box 850ap. I read on your website that the 1500ap should have phase-reversed tweeters. Does the same apply to the 850ap?
Best Regards
Puda

Hello Puda
We are fine thanks, I hope so are you.
The 850a have like the 1500a the connection to the tweeter with inverted phase while the wf and mid are connected in phase.
Best Regards
Massimo

Thanks for the message Massimo,
I’m asking this because I have two pairs of 850ap, one pair has the tweeter connected in reverse and the other pair has the tweeter in phase.
Then I have a one pair of 1500ap, one box has tweeter in phase and the other box has tweeter reverse.
So I wasn’t sure what the original wiring was.
Is it possible that at certain times of production Grundig made both variants of the tweeter connection?
With best regards
Puda

No….someone have change one or both tweeter on your speakers and have wrong the connections
