Still as good as it is from way back in post #5!
I'm not really worried, though Dennis suggested in the BR-1 cabinet, it will affect the lower end.
I completely forgot I posted that way back in January. It's been a long strange year.Still as good as it is from way back in post #5!
If you go to http://www.troelsgravesen.dk/coils.htm you can see various arrangements of two coils where each coil is 0.56 mH. They're wired in series with each other resulting in 1.12 mH. Figures 1-3 show the inductances as the distance between the coils varies from 20 cm, to 10 cm, and as close as possible. You can see the minor differences. Sometimes, with limited space, I've had to vary from the ideal. It doesn't seem to make a major difference. Figure 4 shows a useful trick, if you need it.
The two different diagrams you described are simply different ways of drawing schematic diagrams. They both result in the same thing. Humans may care about the perceived differences, but electrons don't.
Just to clarify... connecting all grounds to a single common point is OK. (Forgive, Physics 1 in high school was a long time in the past. *blushes)
I found two schematic diagrams to illustrate. The first one shows a 3-way speaker, where a single pair of binding posts are used. A number of different ground points share the same wire.
I'm pretty glad to be doing it. When I get the pics up, you'll be able to see the brutal progression... when I changed the tip on my iron... and hopefully nothing else. A year in the making.
You quit your job to work on speakers? I'm concerned.
I thought I was too. And I am. But the battery polarity test said that was a lie.
So it's the fast track for you.
The T and DT have me stumped. I understand QWT to be quarter wave transmission line?
First, I left my job to leave my job. I’ve been in Service Industry well over 25 years... enough so that counting doesn’t even matter. In that time I have done just about everything except own/open my own restaurant: I have served (some), bartender, am a trained barista, done dishes, cooked every station in the kitchen from garde manger to pastry, trained and managed staff, been Executive Chef at a premier winery, and am a Private Chef (though I am not booking any engagements during the pandemic)..You quit your job to work on speakers?

My first foray with a soldering iron (since high school) was the Dayton BR-1s. That was the Golden Age of DIY when you could buy nice cabs from PE and Radio Shack was still open for soldering supplies.
) The important thing is that I’m doing it.
I had originally bought them when I was still planning on using a single board for all the components. My acquaintance's insistence on me trying the 2mH and 100uF components changed that to two boards. *shrugs (Though given my track record, that might mean another 6 mos! )
The last pair of Molex connectors on one of the Tweeter Circuits.
Completed Tweeter Circuit, glued and strapped.
That looks fine to me.
