Looks like 1/2" hardware cloth pressed through the speaker surround baffle using the cut-out portion as a mandrel or die then spray painted black. Just a guess . . . Eggie?
Good guess, but not quite. Welded wire mesh will not form properly because the wires are not able to slide on each other while forming the curved portions. I used a #5 stainless steel woven mesh then painted.
I do think that my speakers are sounding better and better with each build. And also I think that I may have finally graduated from audio enthusiast to an actual audiophile now. I say this knowing that a small percentage of you might disagree, but I have found that my right ear prefers the sound of the walnut speaker and my left the cherry one.
That reminds me. I need to bring some bottles of this wild hops homebrew to hand out this weekend. Just no drinking it there in the main room so the group dean't get banned from the hotel. Would need to chill it anyway.
My speakers no longer fart. After some constructive criticism at InDIY, which I greatly appreciate, I removed the wood side panels from my speakers and thinned down some gorilla glue with solvent, punched holes through the pvc sheet and filled the voids caused by some oil-canning. I also sealed up as many places as I could with caulk in order to attempt to separate the upper and lower woofer chambers. Impossible but but still I must try. Now I would like to find a switcher for quick AB comparisons on different crossovers. I will be using my laptop in mono as a source. What about a remote controlled volume module rewired as a balance control? PE 320-6012
Correct, five of them. They should have been more difference between them but due to leakage between the channels, they were nearly identical. I do not consider this project a do over but the terminus output is interesting. I am not sure of the phase relationship to the woofers front radiation in that entire band, nor the magnitude. I inserted the mic. into each terminus about an inch, to the point before it transitions to an expanding flare. I am not sure how you ported guys would do that and then splice together?
If you want to experiment with merging one of your terminus outputs with the woofer's front radiation, you can easily do this in VituixCAD. Just take a near field (NF) measurement of one of your woofer cones and then load this FRD, together with one of your NF terminus output FRD's, into the top section of VituixCAD's Merger tool (which is called the "Low Frequency Part"). The Merger tool automatically sums the two NF measurements with zero scaling. You can then scale the terminus FRD down in SPL level until the two green curves match up in the 5 to 10Hz area. Here is an example from my Radiusaurus speakers, merging the W6-1139 cone plus port. I scaled the port measurement down -8dB to match the cone measurement.

Oh my goodness!!!
You get a smudge sir!
Those 2.5ways look great, Eggman!

Gorgeous, too.
Like their designer, they have some internal issues that are not immediately obvious to everyone.
Nice work. How were the wire grills formed?

Sweet!

Hmm, I thought that was a bad label? Not sure how I would take it if someone called me an audiophile.
I agree John. I was in a silly mood last night.
I checked the carbonation level of a recently kegged homebrew and I may have oversampled just a bit.

My room should have a fridge.
I'm trying to think, if I had some beer that I wanted to keep safe, would I put it in JR's fridge?

Old XO using my plug and chug method. Notice the asymmetrical null, I think that is a good indicator of bad phase tracking.
New XO
From where did I get this?
Terminus.
