Default 3D Printed Egg Speakers

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
IMG_2304_2.jpg

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

Should have copyrighted the diamond pattern, looks like B&W have copied you :-)

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.

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.

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)
