Verum Audio - Exciting high performance DIY planar

Absolutely the same. Difference is only on THD graph.

 

How do you easily increase the tension in the membrane?

 

You make it work long hours for little money in a bad work environment.

The trick is knowing when to stop or its Michael Douglas in Falling Down all over again and you lose a batch of headphones.

 

If it was easy , we would all be doing it....

 

That is what I thought but, Garuspik said;

I may have misunderstood something, maybe he is referring to the felt mod.

 

Yes, I meant felt mod. Tension is set once and for ever by manufacturer. Sure you can heat membranes but I strictly do not recommend to do it.

 

I'm just glad you aren't trying to make the membranes as thin as humanly possible and all that stuff. Hifiman keeps insisting that this is the future, while their headphones have less and less balls.

 

Frankly speaking I whanted to make a film thinner. That little mdirange haze and roll off ather 16khz is a result of relatively thick film.
But it has some sound benefits and huge benefit in reliability. And I'm constantly searching for a supplier of a sandwich mylar + aluminium film that is thinner then the film I currently use.

 

I know Rinaro is located in Ukraine and are responsible for making the new drivers for the meze empyrean headphones. I'm not sure if they would be able to give information on suppliers or whatnot, but it may be worth contacting them.

 

I really doubt cause we're direct competitors. Especially when the price is 10x times different.

 

in all fairness you are not currently competitors - precisely because of price difference - completely different market - But I need to agree that them wanting to share anything wit you is highly unlikely

 

I mean, that it's a bad thing for hi-end manufacturer when technologies from flagship products reach more mass-market products.

Hm. Very interesting. It's a real fact or an assumption? As any manufacturer I'm very interested in implementing others knowledge

 

I saw that video. It would be much more interesting with traces. As we all understand thinner diaphragm is more flexible and can reproduce higher frequencies more accurate. At the same time because of it's flexibility chance to tear aluminium trace is higher. During this year we'll see whether I've achieved good reliability.

 

When I realized that i'm not going to build TOTL headphones things immediately become much simpler
But for sure, after I'll ship all orders i'll be searching for ways to improve.

 

There is something oddly satisfying about that video

 

My HE4XX has a faulty driver on one side. It's unable to recreate any sub bass. The other one does fine down to 20Hz and below. Yeah, drivers shitting themselves is not a worthy sacrifice.

 

Hm, looks like different excursion. It can be because of VERY different tension (in which I have some doubts) but maybe you're lucky enough and it is some felt\damping material somewhere between magnets and membrane?

p.s. I like He400 series. Imho that was a real breakthrough in affordable planars market after the hegemony of Fostex 50 and it's mods.
