Only 100 hours? (and click-bait — $650k loudspeaker)

They boast that there is 100 hours of CAD work to do this design. I do lots of CAD work drawing loudspeakers. 100 hours is a joke … some drawing sets i do take a fifth that much, that is with flat sheets. As Chrisb says, curves cost money. 1000 hrs is more realistic.

This is what you get if you equate speaker design with Formula 1:

If you have listened to similar systems, you can roughly estimate what this will sound like.
I'm betting on 'Wilson-like' but with a more synthetic/clinical signature.

Such high-tech exercises NEVER even remotely approach the reproduction of 'natural sound'.

After 80 hours of intensive CAD design time, the primary design concept emerged.

How mnany hours before they presented their drawings to the 3D CAD guys, then details, thise details, especially withthis shape would take many more times than that.

The FEA is CAD, as would be the initial XO work —some people spend 100 hours on that.

You missed the "more than" part of the sentence in the posted article. It's poorly worded. But I agree, it sounds like nonsense, so who knows how much CAD time is actually in the speakers, just for the cabinets alone.

I know from personal experience, that CAD time can add up pretty quickly, especially when people don't really know what they want, or keep changing their minds. 😉

Which part?

Leaving the drivers and the electronics of it aside. Commenting as a high-end composites developer;

Very very small boxes brace themselves, as they get larger, they need more bracing (even in the form of wall thickness). If one had ambitions to build very large cabs and aspire to very high end, the shape looks appropriate and the fit and finish is very well executed. Bringing in a pro composites team to analyse and tune the structure also sounds appropriate. The use of high-end composites also is perfect. An F1 chassis builder would be a great source for this expertise

High end composites development costs money. A bwoy can drive a v8 sports car out of the showroom from the earns of designing just one composite part for a brand. 100 and some hours? There is a thread around 2yrs old in subwoofers where I mention modelling similar forms, female torso with truncated limbs. Is a day's work in Blender. 100hrs and a bit sounds reasonable for polishing that to a finished design with the mouse in the hands of folks who know what they are doing

What about the price? Again, let's leave aside development costs. These are large cabs, would like to see some comments on the size of these vs a pair of F1 tubs in material and build costs

Can it be sour grapes?
 
After all that time its still a junk MTM with bad center to center spacing.

Magic baffle shape, to have rear mounted drivers with a diffraction step instantly at the driver.
Genius !!
Its comical how lost the HiFi market with usual high prices to make people assume high quality

For the most part maybe the rear mount round over and magic baffle actually do nothing.
And center to center is just the usual horrible. You just cant see the driver mounting plate sizes
behind the fancy sparkle barf pink front plate.

But im running surround sound lol. 650k for fronts then another for rear.
Darn it.

How can you comment on the fit and finish?
