Just a point on those speakers…a quick look back through this topic and I’m guessing you’ve had them for 1+ year?
It looks like you still have the protective plastic film on them. Whilst I can’t read what’s written on the yellow sticker, I’ve got a strong hunch that it’s a warning to remove the protective film, which is going to be increasingly difficult to remove the longer that plastic film remains in place. Just saying.
Continue forward on your journey, you’re making some nice progress there.
