Will you make any FR graphs?

Yes.

Sash Deux V2 Guy who built those told me it has a 100mm overall diameter and active area is 75mm. Other specs mentioned were 96db sensitivity and 14 ohm impedance.

It's a cool headphone. It can be used both open and closed. Just got them today.

Awesome, not too many planars naked around these parts!

Here are the frequency responses. Measured with mini dsp H.E.A.R:S with 1/12 smoothing

First I measured it closed. I don't hear that huge valley at the center. I suspect that its some resonance from the cups which cancel some of the frequencies in measurements or something like that.

And as suspected, it was not driver inherent problem. Here is open back measurement.
Even though the channel balance is not bad it is partially my system that makes it worse. Right channel always measures bit quieter on every headphone. I thought Sash Deux V2 sounds a lot like LCD-3 and measurements confirm it.

LCD-3 vs Sash Deux V2
To my ears LCD-3 actually has a bit better sub bass extension. I'ts the stupid screws on Mini Dsp that cause some leakage and LCD-3 won't clamp hard enough to compensate for that.

For more reference here is Sash Deux vs Sundara



Sash Deux V2 has impressive resolution and soundstage is bigger than on LCD-3. Despite tonal differences one could expect it to lag behind LCD-3 on other aspects but it really does not. Not by a lot anyway. For $350 it's hard to beat.

To overcome the screw problem causing a bad seal, I use XL rubber bands to add a touch more compression.
In the end it actually makes sense to do this because the width of the jig is about the size of a child's head, so a normal adult head would naturally compress the pads a touch more anyway.
Two birds with one stone really.

Thanks for the graphs.

 

[Roderick]

Thats a good idea. Maybe a sweatband could be used if if there are no suitable rubberbands. I've actually used dx1000 stretched over closed headphones while measuring

Hmm... I should propably open a thread for sash deaux. I will review them eventually but as usuall it might take a month or two.

Ugh.. Can't stand planar mids weirdness. If they want to innovate Orthos, they need to start with that problem.

Revox RH 310 (rebranded Beyerdynamic DT440) from around 1974/1980
It’s the first “large” diaphragm driver from beyerdynamic, the membrane has a very similar shape to that of the DT880 but it’s smooth. On the back the magnet assembly is similar to that of the dt100 and dt220 from the same are witch had a smaller driver. It had a quite complex system of vents and damping behind the dome trough the center of the magnet.
This can be considered as the origin of all beyerdynamic open headphones and of the legendary DT880.

(In the second picture it is shown alongside a 1980 DT880 driver)

Very cool! Thanks for sharing. I love the vintage stuff

Yup, it's theirs alright, thanks! It's quite surprising how strong all magnets in there are!

For the k100 and beryllium drivers, I tried in things with them, open and closed back. I tried to open 1 and 2 holes on the back of the k100, it turns them to complete bass monster, but still sounds bright ir harsh. So it seems there might be something mechanical on the diaphragm making it so, or the voice coil and the magnet system, or even the fact that its its 32 ohm version vs 540 ohm of the berrylium.

So, after frank kinda buried the 50mm K100 in this thread
Some very positive reviews popped up lately, including some preferring them over the aforementioned beryllium drivers (although we dont know if they're the same ones Frank tried)

500ohm:

32ohm:

God, raw drivers are confusing!

Also, new small electrostatic drivers on AE

 

[Roderick]

So.. .what would be the best affordable (max 150€ a pair) driver you people recommend?

I have a set of ath-w10 vtg coming in. Lovely headphones with historial value they just need a driver replacement. I have loads of those peerles drivers (kennerton vali) but what else is there?
