Got a little more work done today. Still plenty left as I want to triple check everything.
Thank you
Thank you very much for the measurements. They will certainly come in handy when I model the walnut version and recess the fiberboard on my speakers. I want to make sure they're just like the original as this will probably have (minute) effects on the diffraction of the speakers, beneficial or not, who knows.
If it's not too much trouble I'd love some more dimensions. I'm sure the trim is very close to 25.4mm (1") from your pics, but doesn't hurt to know for sure. If you could check with a caliper I'll be very happy. Same with the flat outer edge. If I know both of them I can calculate the angle precisely.
Different numbers are thrown around, it's most likely 30 degrees (which some call 60 degrees), because they're talking about the same router bit but seen from another angle.
The grilles I have are DIY and not up to spec. It's not first priority to be honest, as the speakers deserve to have them off to show their glory
Thank you.
As for the ports I'm afraid you are a far more advanced than me. Maybe it has something to do with eliminating floor bounce? I noticed that Greg Timbers recommended getting 4345 up off the floor and we also see KenRick Sound elevate their 4343's in their beautiful showroom.
I do have some measurements (didn't find the near field freq graph right now, sorry). Keep in mind that these have charge coupled crossovers, are actively xo'ed between bass and mid, utilizing 2235h, not 2231A.
This is the impedance of the woofer loaded in the cabinets without any modifications to the ports.
So tuning around ~31 Hz w/2235h
If I can't find the old measurements I'll just take new ones.
