"Tired2way" speaker building.

[Starre]

OK, I do not have a buss bar, do you mean one wire to every component from common, Salas?

 

[Starre]

Lol Toaster, I am new to this so take it easy with me .

 

[Salas]

''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.

 

[Starre]

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?

 

[Salas]

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.

 

[Starre]

Interesting and ty for you impressive knowledge, I will give it another try tomorrow, I am meeting some friends tonight. Again, thanks Salas for your patience, it means alot to me hoping to get these nice speakers to play after all my/your efforts.

 

[Salas]

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.

 

[Starre]

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.

 

[Salas]

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

 

[Starre]

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.

 

[Starre]

I have mounted all drivers to the baffle including some speaker sealing tape.
I have made a slight adjust to my filter (se picture). Will this work good or what can be done to make it better?

This may be a moot point as the board is fairly large, but ideally the axes of the coils should not be aligned. L3 should stand on its side with the axis at North-South and L2 should also be tipped sideways with its axis East-West... I think.

 

[Starre]

Yes I have seen the same but since it is a large board I thought it wouldn´t matter. Thanks anyway and I will maybe use that suggestion since it cannot hurt.

 

[Starre]

I think I understand now how it should be, the wires I added should only be to make connection and not used for woofer and tweeter connection (-).
See picture.

 

[Salas]

That's more like it I suppose.

 

[Starre]

yes but I am trying to arrange it now to avoid the extra wires, I know it should be more compact and smarter arranged, working on it.

 

[Starre]

Ok I think I have it, I hope the coils are not disturbing eachother!
I should probably turn the left coli 90 degrees and lay the big one down.
See picture..

 

[bbggg]

I should probably turn the left coli 90 degrees and lay the big one down

On an East-southeast axis.

 

[Starre]

I will solder it together and check for errors and hopefully it works.

 

[Starre]

The peerless tweeter have some white paint next to one terminal, is that + or -?
