Actually not everybody feels that way. I'm for anything that enhances the illusion of "being there". I'm even more for actually being there! With instruments higher fidelity than any reproduction, radiating high and all frequencies every which way.

Nice one.

Whats the weight/thickness of the foil/paper.

Have you solved your tension issues in some way?

Well done, the speakers look great.

What Hi-FI rules do about propagation of sound, is exactly enchancing of about you speak. If any device in audio line (re)produce something that is more or less from original captured, recorded sound image, it is in same extent less HI-FI. If one speaker can radiate (but) from one point left and right next to straight with same frequency characteristic, even something up and down it is ok, but backward - it is just wrong because there will be additional reflections from walls specialy about high frequencies which care sound definition.

I found some interesting "Gallo" speakers looks like with omni tweeter, but there are not bacward reflections. On contrary I found even some people like dipol ribbon tweeters, but that is just not for discussion about HI-FI in regard what I said ... maybe like some exotic speakers, but ... :-)

I love the sound of dipoles,and the omni as well.
The alufoil is 7my 7/1000 mm. The paper is a bit more. I could remove the paper,but keept it for dampning of resonanses.
I dont know the weight
Here is a better picture:

Omnidirectional speaker concept in general looking like ideal - I am agree very, but backward radiation is overage. Specially about dipoles, they even have not so good radiation left-right like the best I think - omnidirectional ribbon ...

But in such regard, really the best should be newer technology - bending wave speakers where often is no need to do anything for phase coupling between mid and high drivers because all these frequencies go from one point - one driver. It is step forward.

Excellent thread Båndsei!
May I ask where do you buy the foil/paper?
Is it some kind of food wrapping stuff?
I'm looking for a source of that thickness alufoil.
