STDI!, Thank you very much for the reply. I will start with them in that position. In honor of my 69 year old hearing.

I have installed hifikit.se upgrade kit from hifikit, with help from Anders Forsberg. As per the upgrade instructions, I have positioned the red jumper nearest the midrange driver so that it is in the position parallel to the long side of the speaker.

Question: There is one other jumper - a blue ...

I am about to undertake another OA-12 upgrade project; this time using the Satori mid-woofer, Obi T22 tweeters, and filter by grafpro. Parts are ordered.

I was visiting #2 son in Montana a couple weeks ago. He has the pair I upgraded 6 years ago, with Carlsson B65 drivers. Paired with the old ...

Matts,
Thank you for the reply! Got the speaker apart. Nothing obvious. Will try testing connections. There is a shop here that might be able to help too.
