I'm building a pair of the N3 towers, and I've finished the crossovers.  Before I solder and glue everything into place, I was hoping someone whose built these before could check my work.  This is the first network I've built and any expert guidance would be very much appreciated.

The first photo is just to make sure I've connected the components properly, and the second is to make sure I know how to wire them up.

Thanks in advance for any assistance anyone can provide.

 I have previously built several pairs of N3S and a pair of N3 TL towers. Your crossover layout and connection points look correct to me. Good job!

[bprochford]

Thanks, Ron!  I've paid a lot of attention of many of your posts throughout my build process and have found them very helpful and inspiring.  You do great work.

I'll post some build photos soon, so stay tuned.

Looks good.

Hi Brad,

Looks great!

If you haven't already, you may want to consider adding some hot melt glue in order to prevent any resonant induced rattles.

I'm getting ready to assemble my N3S crossover as well.  Are the inductors "bi-directional" like the caps and resistors?  In other words, does it matter which lead on the inductor connects to the appropriate resistor/cap/lead wire?

[Outofthewoods]

Yep, they're bi-directional.

Brad,

Although this is not the best picture to illustrate hot melt placement, if you look underneath each component you can see the glue.

Hi Ruben,

Thanks for the photo!  Now that I know the crossovers are built correctly, I'll go ahead and solder everything together and glue everything down.  I wanted to make sure I didn't have to dismantle anything before fixing it all permanently into place.

I've spent a lot of time reading your posts and looking at your work too throughout this process, and it's be invaluable to me.  Thanks for the support.

Hi Brad,

 I agree with Ruben about using hot melt glue under each component part to reduce resonance. In addition to using this same method myself, I also like to use plastic tie wraps around each component so that they don't pull loose from the board as shown in the attached picture.

I just finished my XO's using Ron's layout (duplication is the best form of flattery) and I'll be posting pics soon.  I do have a question about the tweeter and the Vampire binding posts.

Regarding the Vampires, do I solder the OFC wire directly to the "cup" of the post, or do I use that small soldering tab?  I figure the "cup" gives you a better connection.

Regarding the tweeter, what do I do with that adhesive "spongy surround"?  Does the sticky side stick to the backside of the faceplate, or does the sticky side stick to the recessed cut of the front baffle?

[Ron]

1. You can connect the wire either way, but I personally think connecting directly to the cup of the post provides a better connection.

2. I normally attach the sticky side of the gasket to the backside of the tweeter faceplate. Make sure you get the holes in the gasket lined up properly with the holes in the faceplate.

Could we please get a top down view of that crossover.  Your wiring looks freaking awesome.  I have a n2x kit that I'm building, and would love to take a closer look at your crossover build.

Thanks soooo much.

Great thread!

Has anyone tried anything other then the SonicCap on the N3?  If so, what?

Hi Brad,

Good thinking.

You bet!

Can't wait to see those babies finished.

Hi Devin,

Sorry, but I no longer have access to those XO's. I had some top view pics, but I dumped them. It was sort of hard to follow the lead paths anyway. I'm sure I could walk you through it if you'd like? They were laid out to fit behind the center brace of the Parts Express (Dayton) curved enclosures.
