I blew a tweeter in my center channel. It's basically the Elsinore speaker without the bottom two woofers. I built this about 5 years ago so I can't for the life of me remember what is what! I had it built for me as I know nothing about crossovers so any help would be appreciated. When I took the front baffle off it kinda slipped taking some of the wires with it. The white wire is the positive for the tweeter, and the green wire is the positive for one of the mid woofs. There's also two black wires that aren't connected to anything at this point...
Thanks for any help!

Depend on the filter configuration, there are a kind of filters that the speakers are in series, and others in parallel. Can´t draw an schematic of the filter?
Ok, yes, a common ground for 2 speakers, a tweeter out (the upper in the drawing, it is a high pass filter), and the squeaker (Or midrange) at bottom, it is a pass band filter. I don´t know why the resistors shunting the inductors. I never saw such a wiring.
Why not. The unused one is the ground/negative terminal. Both negative cables (should be black) from woofer and tweeter can go to the same terminal. I see no soldered connection on the terminals 🙄
I would wire up the two filters completely separately. One filter for the bass/mid and the other filter for the treble.
Take the four signal and return wires back to the terminal panel.
There you can decide if you want a single pair of terminals or a dual pair of terminals.

There is a wrong set value of L1= 1,21 mH in the tweeter section. This is
likely the reason why the tweeter blew. Such a big coil can not protect the
tweeter from lower frequencies. It is also kind of strange that midwoofers are
wired in series. I don't see a practical reason to do that especially having
2 pcs of 8 ohms midwoofers.
Maybe the midwoofs are 4 ohm! Resister shunting coil is like baffle step correction! It's hard to tell what is connected to what in the photo, but the schematic is clear and straightforward. Shouldn't be to hard to trace!
Good luck

Hi,
L1 is the correct value for a textbook 2nd order L/R for 8 ohms @2.1KHz.
Sadly text book crossovers are nearly always wrong for real applications.
The layout of the inductors is poor, they will interact, they should
be orientated orthogonal to each other using all three planes.
rgds, sreten.

Received the new tweeter today. Also have a buddy going to do the soldering. I'll report back tonight or tomorrow.
Also, with all the talk about how my crossovers I emailed Joe who designed the Elsinore's to see what it'd cost to get him to build me the correct ones.
