Wiring the 3107 crossovers in 4350

[neanderthal]

I have a wiring diagram but it isn't clear enough to see which is positive and negating on the drivers.All Iam asking for is for someone to bail me out with a clear diagram to confirm what I think is correct:

2405 orange to+ and orange with black to -
2440 yellow to + and yellow with black to - or opposite on this
2202A white to + and back to -

There is a red and black with male spades that Iam assuming conncts to the back and is power in with red+ and black-
Thanks in advance for the bail out on this

Here's have I have. I think your are correct about the spades. The rest should be easy enough figure the 2405 is connected to the Pot

I had that same diagram but I can read the one you posted and the one I have I couldn't see the positive or negative on the 2405's and 2440's.I also thought it was posted on here some time back (I couldn't find it) that the 2440 is wired backwards 180 degrees out of phase I believe how it was stated.

Sorry for bumping this old thread, just to make sure - RED is (+) on the back terminals for both? Are the 2x 15" woofers IN or OUT of phase with the MF/HF?

The electrical phase is reversed on the crossover pcb. The red wire goes to the 2440 positive terminal

Go to this thread. Note unless you are using an original 2440 diaphragm the 3107 voltage drive to the horn will be sub optimal (bad choice of words…Lol). This is because the 3107 allows the 2440 to operate full range above the high pass crossover point.

The 2441 and later compression driver had increased high frequency response. This required a low pass filter be added on the horn crossover output (3155 network).
Search for the Giskard 3155 equivalent network.

Once to settle down and listen to these things these details become important for long term listener enjoyment. The 4350 was designed to be flown from the ceiling with the HF components on the bottom. This way you won’t necessarily have the woolly odd sound with the 4350 right side up when sitting on the floor. It’s not a domestic loudspeaker.

Rick (KenRick Sounds) came up with a new baffle layout using a diagonal woofer layout which is reported to minimise the above issues for domestic use.
