The theory is Great but the practice is always evidence.

This is the formula and steps I took to replicate the curve of USD waveguides using the Fibonacci sequence rule. Amazing taking this process revealed they used the Fibonacci sequence as well to design the curve. I was told even Bang and Olufsen lens used the Fibonacci sequence. I think it's a big part of the secret to great sound companies using this theory from sound engineers. I realized this when I saw the curve and thought to explore the process. I always use it in the design process to work out curves in architecture as it's translated back to manufacturing when communicating the angle for the process machine setup. throughout the industries.

When I studied Architecture I focused on subjects that had a relationship with sound. With a Greek heritage Amphitheatres always interested me. You will even find the golden ratio in these buildings.

I discovered all this in Sound Scape Engineering called Sial.

Professionals that determine noise FQ SPL and more for Airports and other architectural spaces under regulations or just for musical galleries.

During my studies, I designed a soundscape installation around 1K using passive power as the main focus. I had access to the latest sound technologies tools available for the era, and since I had a massive background in Car audio from my car audio shop 25 years ago so I designed a project using the USD Waveguides forum as a reference to produce a passive installation that was only focused for the FQ soundwave to direct and stay true to the source but could be tuned for a wider band for different spaces.

Here is more for reference on how it works in practice. here the driver is the sea https://mymodernmet.com/nikola-basic-adriatiac-sea-organ/...

To cut a long story short.

Since I have my own laboratory at home now and use it for soundscape and 3D Printing Architectural projects I thought to do a design for the Boom or Bust 3D challenge. here is the link to see the outcome. https://www.youtube.com/watch?v=QkWvSwpZNwk

it demonstrates there is a lot more to using this theory.

Will surprise you that it performed on average better over the utopian enclosures on a wide band focused for the target brief FQ's.

Now with 3D printers, I will explore new forms of sound devices using the Fibonacci Rule for car audio in a passive install.

Great for exploring before making real scale first. We do this in Architecture buildings before investing and real scale. all mistakes can be learned during the process of development at a small scale first. .

The Fibonacci order enclosures I designed for boom or bust using my own sequence for the Fibonacci theory demonstrated the differences between a loaded enclosure with a Fibonacci waveguide horn and one without it. I have some great designs and experimental builds coming up. I now do this for passion and not economics like when you own a shop and makes it hard to explore.

This is what makes car audio fun the unknown.

The USD Audio waveguides use the Fibonacci sequence in X & Y but not in the Z axis. The technology of that time was Autocad 2D R13 and forms like Fibonacci were used as a design tool.

The Fibonacci waveguides I Design explore the z Axis and add another layer to the soundwave exit, allowing it to be tuned with more natural materials for center-refined cords to reflect the focused instrument played.

Using the Fibonacci sequence in Z with a simulator allows you to extract the data and work out an angle for the Z axis to differ from left to right by adding parameters to simulate the direction and time it takes for the drives ear to hear in sync. my last video shows how I add pressure to direct the angle. we do have DSP for that today to solve that issue actively but this can be used in a passive way for a purpose build. .

"3D Printing Fibonacci Waveguides"

I Printed these on an angle to optimize the 3D Print to work in motion with the design curves. once-printed it reveals the Fibonacci curve pattern in the print. looks Awesome.

Note the version I build is an experimental model and not to scale.

ideas are to have new and add-on prosthetics to the existing waveguides to fill in the void. Just my Theory would explain the harmonics coming out of the plastic thus why we had to dynamatt to stop them from resonating. .again just a theory.

Good to say these will form part of the Fibonacci order enclosure family. Sound by nature. Will have files available soon for the community to print. Good time to buy one now.

Fibonacci's Theory is in nature all around us will be good for others to explore this as well.

Added plenty of photos to share my research and practice new upcoming designs to explore for the DBDRA. Will be fun to see in real-life applications.
