I built the loudspeaker enclosures according to this plan:

The construction is described from post 325:

Are these yours? Love them, might copy some of it when I some day will build a new cab for mine.
Yes, these are mine. This was my first attempt to build a case that was treated with hard oil. The enclosures have the advantage of being closed or bass reflex or vented with aperiodic valves. There are interchangeable plates in the base. These plates can be designed as a sealed cover or with holes for pipes or valves. Well camouflaged.
No. I did buy some measuring equipment years ago, but I don't think I got any reasonable results from my measurement tests. That's why I rely on my hearing. I think it sounds a bit more balanced, but it's also possible that it didn't help. I just felt like doing something.

Here some pics from my Fane's:
I covered the wide bars with acoustic insulation board from the inside. This softens the middle tones somewhat.

that means there as some resonance, although the metal frame "suppose" not to RESONATE but most of them do
and that cause the diference you hear
if you have the means
can you do a REW sweep before an after ?
to see exactly where the peaks of the resonance were
anyway if you like it, you like it 😀

But your are in the country of the perfect and accurate measurements !!, but I'm not familiar with REW. too much high-tech
German engineers are known for their precision and accuracy for their inventions and designs.
Not to say the tools !! Best in the world !!
definitely there is reflection from the basket through the cone.
And this damping is audible
If damped it makes a big difference in sound. Maybe not so easy to measure as it is a broadband reflection and less loud than the directly emanated sound
it comes close to signal to noise ratio in electronics

Hello Dieter,
I have a few questions:
Greetings Mirko
I have a few questions:
- where did you place the reflex tube? Back wall or bottom?
- How many hours have the Fanes already played? Or are they still new?
- Have you installed a frequency crossover?
Greetings Mirko
Hello Mirko,
the Fane are already new. For the First time I take a MiniDsp for correction. The reflex tube is on the back. This are the responses in the near field and in the room:

When new, the Fanes are concise in the mids. Let them play in for many hours, then the Loudnes effect will slowly appear.
Is the dip between 1500 Hz and 4000 Hz caused by the DSP or is it also present without correction (room-dependent)?
The microphone was placed direkt at the Speakers front in the Center of the Fane. I think there are interdifferences. In the room measurement it looks better.
