There is so much happening, I can't find time to write up project logs. The project is seriously ahead of the logs so far...

I have the speaker with feedbass built, I tested it, it was great, but then I found weird temperature effects, and now it looks like it is not working as it was supposed to, and good sound was essentially a coincidence.

Now, this is the latest stuff I found out.

That microphone response looks really weird...
