First pictures of my mid-bass horn, painted

That is what I was thinking. MDF dust is some seriously nasty stuff.

hi

yes, your are right. I bought respirators for my woodworker, and had a hard time to convince every time, i went to the factory, how important it is to use it. He uses it now. I should delete the first video, and post a new one, where he uses it, to avoid this concern of whom is assisting the video. might someone know how to delete videos on youtube. i have tried to find the function, but have not found it.

You could try the link above to find information on how to remove video's from your your youtube account.

BTW, I have also checked your blog, and I am very impressed by the speakers being pictured there - do you build the entire enclosures yourself?

hello

thanks for you advice. I had to log out, and sign in to my account again, to get this function.

the cabinets are made by professional woodworkers. I do the design, and supervise the fabrication process. This cabinet takes about 250h of work to be done.

I can imagine the process taking that long - the design (and finished product) are stunning. The realisation of the hole in the sloping upper baffle alone would probably give me sleepless nights...

Now, that is a really lovely horn.

The 150hz-600hz region isn't really midbass. It's more lower midrange, the lower trumpet range or lower voice. The 80hz-200hz range is more like midbass, the lower half of the cello range or the upper half of the bass guitar, kick drums etc. This region is very difficult to make a horn for, as you still want some midrange refinement but the horn gets VERY big. The lower bass (40hz-80hz) is easier in some ways because refinement is not so necessary. The LABhorn for example.

hi NL

that's good input, to give the right definition to things.
i use a Aura 1808 below 50hz, and cover the 50hz - 150hz with a upper basshorn, picture below. Since its a snail, it has no folds, the sound is not compressed, and artificially " dry ", what most would define as fast and quick, but full , warm, soft, defined and controlled at the same time, with a good tonal balance.In my opinion the edgy folds of basshorns take off a lot of tone harmonics, which get lost along the way. That was my feeling when i had the Klipschorns. But what i enjoy most , is that the source of the bass cannot be detected as easy, as with a direct radiating woofer. The sound is emitted from a much larger area, from the horn mouth, and fills the room in a more even way. Probably not even a bass array is capable to do this with so good results.
