Spherical Speaker Enclosure (Ported) - Dayton PS95-8 by B_Rich - Thingiverse

I'm a newbie, so i have NO idea what i'm looking at.
But i like the way it looks !

What are your thoughts on it ?

I'm about to start the build of a set of 0.4x karlsonator, but those "drops" stoke my curiosity

Thanks !

Laurent

Guess it depends what you call expensive !
The author of the model printed it, and used 700g of plastic for it; roughly 20.

Not much more than any other box you'd make, so for me it's ok

But it's the accoustic part that bother me more.
I don't want to waste 20 for a shitty sounding piece of plastic

Not 3d printed, but I used two ikea bamboo bowls in a similar speaker with great results:

Good luck with the karlsonators! They sound great.

You can print the walls hollow, and fill them with sand or concrete. Only the mounting points need to be thick.

Is there any sonic benefits to this shape? I also got a printer (Creality 10s recently) and been looking for a speaker enclosure to print. I would print it with thin walls to save print time and fill it with epoxi or concrete. I wonder if the 0.4x Karlsonator could be redesigned into a shell and printed?

Default Ask B&W, they built a business on that shape.

Have a look at the B&W 801 Nautilus and you may see something familiar. With that shape, it doesn't need to be thick at all. Unlike a flat walled box where the sides bend under pressure, a tapered complex curved vase shape like that has to stretch under pressure and is much stronger. So 5mm thick would be amazingly stiff. It does confuse me that they left a sharp edge next to the driver.

I was thinking if we could designed a "Nautilus vibe" into a Karlsonator enclosure. Most 3d printed enclosures looks the same as stacked mdf/plywood. Very few is taking full capibility of a 3d printer. Printing with 5mm walls would probably take 48h+ to print just one enclosure. I'd much rater print it on 10h since you have to watch the printer from time to time. The fail factor increases with time.. I also don't like running the printer at night cause of fire hazard. Pouring different liquid mediums into the thin walled enclosure would let one tune the wall resonnance as well

I might print the last one, as it appears to be an update from B_Rich design.

1) No pegs - by running the wires through the port at the back it affects sound properties
2) I couldn't make the numbers work on the volume to frequency tuning.
3) No Access. I wanted to add accouti-fill to my set and I wanted a way to access the internals in case things went wrong.
4) I like a design challenge. The locking mechanism for the two halves is something I am pretty happy with.

Hope that answers your questions.
You can find his design here.

If i print it, it'll tell you how it ended and how it sounds compared to Karlsonator.
Sadly, no testing hardware, so I'll only provide feelings, not numbers.

Cheers !

Plastic will sound like plastic.
Wood will sound like wood.
