Default The Spheres

Finally finished these guys tonight. The exterior finishing took the longest by far.

Anyways real easy to do, and fairly cheap.

check here for details <will update soon, but you get the point>. They are running full range right now. They definently need some help in the bass department. May have to throw a Sonotube together.

Anyways enjoy

Those look very very neat! Kind of futuristic.

I don't mean to be overly critical, but have you thought of a different idea for the stands?

I think that if you could get a metal rod and bent it into a stand, it would look much more... hm.. architectural, or like a sculpture.

I'll definitely check back when you've got the construction section on your site.

No I totally agree, a metal curvy stand would be better, I just needed something quick and easy, the stands cost me like $10. But ya tubes would be better.

Looks great

To reap the benefits of a spherical enclosure you might want to try a much larger one and mount the driver into a meatier part of it, i.e. without the baffle protrusion. At the moment, you're actually closer to a driver mounted at the end of a cylinder which is at the other end of the scale for a smooth baffle diffraction rolloff.

Off course if your goal is a compact and cute enclosure with high WAF, then great job!

I noticed this weekend at the local B&Q DIY depot (UK DIY chain), that the garden centre part had some approx 33cm diameter earthenware spheres with a fetching blue glaze. There is an approx 16cm circular hole in the sphere. They look ideal for a spherical speaker enclosure!

(there were also some bevelled-edge earthenware cubes with the same finish. One size was about 28x28x28 cm, the smaller was about 18x18x18 cm. Also with a hole in one of the faces.)

Have a look at Anthony Gallo Acoustics and look at the front page

Just point out with baffle step they will be ~ -9dB at 150Hz.

An RLC parallel filter is recommended with C simply
used to recover some of the higher treble,
or use line level EQ.

I'd love to know how you worked that out
Are you treating the cross-section diameter as the baffle width? Or the effective diameter of the cone?

Just assumed baffle step will have barely started at 150Hz,
though it might have started slightly, say +1dB at the most.
