Simple is best. Is that a Nichicon Gold electrolytic?

I've got a couple 6.8 uf Clarity Caps coming for these and will start with adding a 1 ohm non-inductive wire-wound resistor in the tweeter circuits.

Do you feel there may be a sealing issue between the factory plastic tweeter bezel and the thin baffle housing that it is clipped to?

The electrolytic capacitor that I’m using is a ‘state of the art’ Audio Note Kaisei ‘bipolar’. Normally I would use a film cap for a speaker, but thought it would be interesting to experiment with a different approach, to see what the end result would be. After all, Audio Note have assured me that their cap would work safely in my project.

I don’t see a sealing issue problem  with the tweeter.

Thank you for sharing your port idea/pics.
I have another set of these platforms that I'll experiment with. Judging by your pic. I shouldn't need more than
an inch long tube within the box to achieve port volume....

Sorry, tried inserting image here. Forum neophyte blues...

Interesting project you got there. Here are photos showing my method for attaching an aluminium rear panel…

I've wrapped up the Polk near field project. Looking forward to
modifying these so I can have the tweeter up near ear level while listening on the PC.

Did you glue those rods in, or also bolt to the front as stanchions?
I ordered thick billet plate to machine a slip-fit, but want to experiment with factory rear panel first.

The rods are ‘threaded brass’ circuit board spacers (two screwed together). They were attached to the speaker cabinet with double sided automotive tape. Then I smothered a layer of ‘outdoor wall filler’ over the sides of those brass circuit board spacers to permanently hold them in place. They are not bolted to the front baffle as stanchions.

Ok. Thanks for the explanation. I started dissecting the midranges today for new butyl surrounds. Went ahead and removed dust cap to confirm pole-piece is 0.997" OD

Well, think I figured out how to upload image from PC. Mobile not the case.
I'll try and start my own build thread here. Don't want to step on any toes.
These are on the way and started looking at cabinet modifications too.
Aesthetically, I want these Beovox to mirror my custom Polk MTM's...

Interesting. Make sure you film the finished CX100’s playing some music. Then post the video on YouTube.

Posited the question... For the tweeter, wouldn't this have made more sense?

I don’t know. Jeff recommended for me to keep the original circuit layout, but with the slight modification. What will this do to the sound?

[xschop]

I'll do that test very last since I have the x-overs externally mounted.
Still waiting on new surrounds. I did the full gamet of basket mods including open-cell inner frame foam mod and bilayer frame dampening with high density polyurethane..
I lightly doped the cones with a latex polymer, but didn't dope the woofer dust caps...

Replaced rotted diffraction foam with 3/8" thick wool...









Billet alloy bezels will be adapted...

Dark Charcoal Hammer patina should match the drivers nicely. Seems the factory enclosures were sprayed with a dark olive drab looking color. Drivers are finished with new butyl surrounds.

[xschop]

All machine work done for these. Time to assemble.
Tried starting a thread but the forum blocks me.

I have not seen a notification of any kind if you attempted it here.  However, you probably need to review the rules...

Nice looking speaker. Could probably get away without using using the covers
