I have finished the surround speakers.
Wiring thick cables of many thin strands together is a bit tricky. Here’s a neat trick I did to not lose my mind while burning my fingers off.
The sound have not changed much to the old ones. They are one speaker less and about 2/3 of the size. The sound is not as deep but given that they are going to play the surround channels they are well up to the task.
I tried playing music at full range with them and they sound a bit thin but still lots of detail.
