Of course i can! Why not :?:

(to try)

I was little confused about this, but...

One problem with variable depth helmholtz is that they won't exhibit the same properties at other than perpendicular incidence, unless you build individual separators between each slat so you have several small, INDIVIDUAL Helmholtz resonators.

You want to say that 1st version of resonator can do the job (of course to calculate correct slat/slot/tick) :?:

The oscillating air in the resonator mouth is the mass.
The mass doesn’t change in order to your drawings.

The air cavity behind the slots represents the spring.
It can be also seen as: the part volume behind each mass represents a spring.
The stiffness of the spring becomes softer if you increase the air cavity and vice versa.
What you get is a parallel connection of different spring stiffness anyway.
So you don't need to separate the volumes.

Sounds great

So if I don't try i will never know how that really sounds :roll:

Thanks Interface, and thanks for drawing :wink:

So, moby, you promised some pix and stuff... dunno if yer still around, but it looked like a funny plan... so, bring it on!

Yes, I forgot to do that :oops:

Resonator works like charm. Will post the pic's soon :wink:

Here are the pic's

I included the .skp if you want to craft :wink:

Feel free to ask about details.

cool. Dunno if I like the Green colour but for the rest nice job and thanx for the pix!

If you wanna ride, don't ride the white horse. That's why I choose green :wink:

What is the practical comparison of this type of "gobo" or baffle vs. a regular "gobo" or baffle. What does this moving resonator do to the sound in the room as opposed to using basic OC 703? Besides the fact it looks really cool...

Thanks!
