Looks more like my Logitech webcam done up in wood. :D

Looks like something growing in the corner of my basement.

Mildred!! Someone stole the knob off the bannister again!!
"How did you like this speaker?"
"Like it?? I had a ball!! Once I got around to it."
Hey, isn't that one of those things that my grandmother used to store her wig on?
"...and now, class, down over here is Australia..."
Is it me, or do you see Roly Polie Olie in this design?
Now, this could be naughty, but if we can have a carrot, we can have a loudspeaker :D

The speakers were made in Belarus - a rather large ex-Soviet country that not many people may know about;)

Omigosh--you found Aunt Margaret's opera glasses!! :D
I wonder what components they're using in these speakers. Can imagine they cost a few bucks...
They actually use Scanspeak drivers, and Scanspeak is an old and very well-reputed Danish company in that area.

I'll bet that that speaker would image very good because it does not have a flat front baffle.

Should check my speaker component catalogs--I know Parts Express carries Scanspeak.
About the baffle--the original Boston Acoustics A-series speakers (the larger original models, like the A70, A100, A150, A200, A400) had a very large front baffle area, which caused the drivers to operate in more of a "half space", according to their theory. The A-150s I'm working on refurbishing throw out a very nice image.
Some have considered a sphere to be the ideal speaker cabinet--free of internal resonances (no parallel sides), and no cabinet edges. I'd be more interested to know how they make the cabinetry!

The sphere is made up of laminated pieces of wood. This is noticable in the top image (single sphere). I would guess that the shape of the sphere was made using a large lathe. I wonder how much of the interior of the sphere is hollow?

Wow, nice workmanship! I dig the way the wooden device that holds the tweeter is "squished" between the two larger spheres.
Gallo Acoustics made speakers like this - out of spun aluminum. I have a pair of their discontinued Reference models. They sound great.
Their current line still uses spherical enclosures.
Several companies are including curved enclosures as part of their speaker designs. B&W in their Nautilus speakers, some KEFs and Cabasse. There's something to it.
