3D Printed Egg Speakers

[dr frost dk]

I made these 3D printed egg speakers about a year ago and now they are ready to be posted (many things had to be worked out and tested), many color variations can be made 🙂


Sound with the sioux unit is very good, well Make: Magazine posted them as Audiophile speakers, i have been using these units for 10 years and have never found anything that comes close to sound and price, just needs a tweek with a small upgrade to treble crossover
3" Egg is based on the W3-871SC unit, good sound but very little bass, with a sub they would make great satellites and they are cute, have been thinking about doing a 2" also

For now i have 3, 4 and 5" sizes but more will come later, TDA7294 + Transistors will also be in various versions + Class D amp(s) in 3D printed cases

Also made a case for a Car radio, TDA7293/4 is also on the way

Very nicely done!

Should have copyrighted the diamond pattern, looks like B&W have copied you 🙂

hehe well not quite the same pattern, mine's triangle the bowers looks like pentagons

A "Juke Box" shaped cabinet looks interesting.

For desktop speakers and music monitors located near the walls, it can be desirable to create a baffle shape which produces mainly forward directivity down to wavelength=cabinet_width, and also has large radius quarter rounds to reduce edge distortion on longer wavelengths.

Juke Box = 180-degree baffle waveguide down to wavelength=cabinet width. 180-degree baffle waveguide up to tweeter's natural beaming.

good stuff there.


Here looks like b&w, but I'm unsure.

I have two sets of big egg speaker prototypes made by Leigh Industries but never issued commercially. Quite nice speakers which I use for our TV.

Two-way, they have XOs resembling the famous BBC-Rogers LS3/5A with 18 elements.... which is where you end up after careful testing of any speaker.... unless you just go bi-amp DSP which makes a lot more sense today.

RGB version ("transparent" with 72 ws2812b diodes) will have a video out soon'ish, will post here when ready, this is like the 3" i posted almost 2 years ago, but in the new design and WAY cooler light

Audio is not the best, but RGB versions of the Egg speakers (4") are getting there, only 2 patters in this video (split in the middle of video)

going to be 3 videos up soon (3 songs) to show the light system, have 18 patterns so far, still some tweaks to do, another demo video so far

Hello Heine ,

Could you produce a .stl file of your Egg without the reflex port in the front and thus a somewhat shorter baffle/flat front section?

Thanks ,
Eelco

Somewhat similar to the spherical concrete speakers I made back in 2000. Sphere-like shape is wonderful on the outside, gives smooth baffle step, but terrible on the inside, because almost all dimensions on the inside are the same giving a terrible standing wave resonance. The egg might be somewhat better than an exact sphere though. I ended up stuffing the inside of the sphere heavily with polyfill for the closed box version, and installing a tilted inside wall that cut the inside into a half sphere in the ported version to reduce the standing waves.

Maybe in the future, right now im concentrated on finishing up patterns and documenting the RGB´s to go online, next laser weapons, VERY big printer, Velomobile etc so can't make any extra stuff anytime soon

Shame, port on the front almost kills it. Meshmixer should erase that port, cover the hole and eliminate the ugly diffraction it creates. Ehh easy enough to make a real plywood baffle.

well then do it and post results

I feel at home watching these. I have Scandyna Megapods + Blueroom Bass Station and another set is Everything But The Box Pluto F + Subterranean Model One.

Finally got the last things done on the RGB system 😉

So a new video out showing lights and APP (webserver)
