A poetic write up.
“Shouts from the audience seemed to be coming from all around me, with entirely lifelike dynamics. At one point, I heard loud clapping coming from directly behind me; I turned around and saw only an empty room.”
Yup…that’s what I experienced.
I wish I could make that happen in my living room!

Hmm. That remind me of some experience i had with ( very good) loudspeakers which made people have stange reaction:
Hitting playback and seeing the player looking at the piano to see who is playing, or talk to someone you believe is in the room with you ( when he is in the studio and there is no talkback activated ( you listen to the microphone you are going to track.
William if you read this, i wonder from what cause this effect: coincidence of drivers, phase behavior, low interaction with room? A mix of all this?

Best line from the article "The FS-1 struck me as both original looking and attractive—let's face it, many modern horn speakers look like snow plow accessories."
A bit too triffid for my aesthetics, but always happy when there is a genuine merging of engineering and craftmanship.
High DI across the midrange and treble, which minimises room interaction, is essential for realistic stereo imaging in an untreated room. Nearfield listening can also be used to minimise the impact of reflections from the room and its contents.William if you read this, i wonder from what cause this effect: coincidence of drivers, phase behavior, low interaction with room?

Coincidence and close speaker matching are also important. I always design crossovers to phase track through the crossover region, but don't aim for a flat phase response. I fully corrected the phase response in one of our models, and it doesn’t sound different or remarkable in any way, to me or a few others that have listened to it. As always, YMMV.
wow those are some very cool speakers, like hi-tech oswald mill audio speakers 👍
good heavens at first read I thought you said a "MEAT vegan brownie"and visions of meat lasagna were conflicting in my head...they make a mean vegan brownie in that cafe.
...at 136 dB the café could just use the sound pressure for cooking...
Is "vegan" legal in Australia? ... askin' for a friend.
Are there any measurements of these beauties?

Sadly, yes.Is "vegan" legal in Australia?
reminds me of the line in 'scott pilgrim vs the world'. "chickens not vegan?"

LOL…how did we get to this point in this thread?
I’m not a vegan or a vegetarian. That being said, the cafe had a bit of a “New Age” flair and my choices were limited. I was simply surprised that I could enjoy anything vegan to be honest!
On another note…
I was wondering if William would be willing to share some information regarding his experience with laminate constructions?
I have some ideas for creating a new open baffle bass section for one of my projects with more organic lines.
There is a maker space I discovered near me that has a CNC router table with a 4 X 8 sheet capacity.
I’m wondering what you feel is the best software for a complete beginner to learn in order to create 3D objects and slice them up so that a proper file (.STL?) can be created to cut them out with a CNC router?
I’ve read that it’s possible to do with Blender.
It’s free and I downloaded it.
However, the learning curve may be a bit steep for me.

LOL, yep there are plenty of them. Personally, I eat vegan cows and sheep.Is "vegan" legal in Australia? ... askin' for a friend.

There are lots of measurements. We are still undecided what we want to share. The high end audio industry seems to have an aversion to measurements so comparison will be difficult for the non technically astute. Few people can get a good idea about how a loudspeaker sounds based on measurements. They look at the speaker and make up their minds!
Our CAD guy uses Rhino to turn the shapes Rob and I give him into something that can be machined on the cnc.
We vacuum bag the pinned laminations to make them tight. For anyone who hasn't used a vacuum table, they can provide an immense amount of pressure over a large area. A stack that has not been laid up correctly on the table will be smashed under the force. You'd need a LOT of clamps to get similar clamping pressure. This is key to a successful stack lam.
BTW, I've had those brownies too, and they are surprisingly good!

Chris wanted to play with the vacum bag. The form was more work than the box.

A very powerful tool.

I find Fusion 360 to be the easiest 3D CAD tool to learn, to me it makes sense and has a fast learning curve that is not too steep. Effectively you draw sketches on planes or surfaces and then, extrude, loft, sweep etc. Most parametric CAD programs work in the same way. Fusion has CAM functionality too to create toolpaths and is free for hobbyists, there are limitations from the paid version but they don't stop you from doing anything important for single projects. There are lots of youtube videos and forums which help to learn how to drive it.I’m wondering what you feel is the best software for a complete beginner to learn in order to create 3D objects and slice them up so that a proper file (.STL?) can be created to cut them out with a CNC router?
CNC machines use similar code to 3D printers to program the moves, there is enough variation to make it a good idea to talk to whoever runs the place to make sure you choose compatible CAM programming.
Rhino is incredibly powerful but it is a surfacing tool and not a true solid modeler, it is also quite hard to get to grips with if you have never used it before.
Fusion also integrates well with Ath as mabat has created some scripts that allow the waveguides created to be imported quite easily.
I stopped by the A for Ara workshop this weekend to take a tour and have a listen...what an incredible set up. CNC, metal mill, finishing room, the works. Very friendly host as well! The sheer amount of experimentation and thoughtfulness that have gone into these speakers is super impressive. Learned more than a few things as well, like the engineering reasons behind the petals (you want a sectioned horn for strength/stability to prevent seasonal wood deformities).
As far as the sound...despite the reverberant room, these boys image incredibly well and they were super clear to my ears, with just a single coaxial in the throat.
I'll also mention one of their bookshelf models, a two-way "half horn" type model designed to limit horizontal bandwidth outside of listening position. Would work great as a nearfield monitor. Definitely DIY-able. Can't wait to visit again and see what else is cooking!
