''Buss bar'' is the concept. Common in old tube building. Check out a Jadis amp guts photo on the web to picture it for instance. Could be a thick wire. The idea is you progressively tap along the ''bar'' from lighter to heavier current points and you ground at the end. Say in this case you stick the tweeter (-) then the woofer (-) then the conjugate (-) then the amp (-). So heavy currents don't mix with lighter ones.

Ok, but the main thing with star earthing is that all negative points from components is soldered in the same physical point with no wire inbetween them? They originate from the exact same physical point to aviod any hum?

There will be no hum in speaker level, that's in delicate signal electronics with PSUs around etc. But it will be cleaner for return currents. Either are good practices. Prefer the pure star if you can arrange.

No problem, was no big effort. Yours really the effort. I wasn't expecting someone to pick up that one from a general discussion anyway. Wasn't meant as a building suggestion, but what the heck, nice try.

Yes, I liked the idea of a 2-way with 8 inch woofer and since I am new to this you must start somewhere, and I would never be able to build any speakers without some help from more experienced people. I know it was not meant as a building suggestion from your part, but I liked what you and your friend came up with.

Will you brace front to back also? The original has two crosses.

Yes I will do that, the braces are ready to put in place when I finally glue the baffle into place. I will have one inbetween woofer and tweeter and one just below the woofer. I will show a picture later on and you can see exactly.
Have a nice evening, bye for now.
