OA-116 jumper positions
Posted: Mon 22 Sep 2025, 00:15
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 one - on the front plate with the tweeters. It has 3 possible positions: forward parallel to long side, rearward parallel to long side, and rearward perpendicular to long side. What is the effect of those 3 positions on the sound of the speaker? I assume they adjust the brightness of the tweeters. I kept the original peerless tweeters in place - for now. Any information is appreciated.
