Orthodynamic Roundup - Page 1382

C'mon Nick, you know you wanna.

 

/peer pressure

 

Plastic from a roasting bag (packaging has the PET symbol on it, that's all I know) seems to work as a substitute of sorts for the moisture guard on the Unipolar. I tried wrinkling up the film before attaching it (like some pros seem to do it), but that didn't come out so hot even though I tried three different versions. In the end, I put on a smooth film of it. Although when I say smooth, I mean not really smooth - it has a few folds in it that were there to begin with. And I attached it with duct tape, since I've no proper glue. No pictures; later.

 

Colorful graph (raw data). Spikes in the lower mids and below are interference. The cover was applied only to the front of the driver.

 

The graph shows a bass hump in all measurements, but they were measured with no baffle, i.e. the driver was loosely in the cup and the mic setup was pressed against it. Doesn't give the most accurate response graphs, but does show the relative differences; so I'm not sure whether they actually have a hump or not at this point.

 

Also, the Unipolar aren't exactly orthos I know, but I don't want to advertise them so much as to create a proper thread for their modding, and since wualta was asking for info on them, into the ortho thread it goes. And in any case they're planar headphones, can't argue with that.

Nick. It does have adjustable venting. 

yes I certainly don't mind seeing electret/planar type stuff like the Unipolars in here. Keeps it interesting

There's a little bit on inner fidelity.

oh the torture, guess I will go read that Beyer -fidelity article again.

Wualta if you are at all curious as you seem to be, hit up the Amazon page for them some good shots. And headfonia. Apparently these are the definition of cool. no kiddin'. Theres even a hipster modelling them and having to hold onto them in a dynamic manner, a manner that's so hipster and obscure we have probably never heard of it.

Q: how many hipsters does it take to screw in a lightbulb?

A: I dunno it's a pretty obscure number you have probably never heard of it

 

At least let me pretend i don't want to hit the mouse button and have something magically show up at my post office.

 

One planer old idear I have been toying with is damping the Stax SR-5 to see what comes of it, if I can grab a tidbit of bassery without affecting the open sound too much I won't need to blow $ on the SR-5 Golds later on. PWB managed it I should revisit them and see.

Media headphones (those cheap ones used for home theater systems) have been using variable bass ports for a while. Though many of them would gain openings on the baffle for more inside-cup-to-between-pads-and-ears air/wave flow.
My cheap MDR-XD200's did that, hence having a Music<-->Movie switch. It just raises a trap door kind of thing.
Though Sony is into these kind of weird ideas so it isn't entirely surprising to see their older stuff come with all sorts of fun gimmicks.

I think the new Tiesto-AKG stuff also have variable bass ports?

Wualta are those common? Guessing not. I will keep my eyes posted see if one rears it's tiny(?) large(?)  orange ( edible?) face

Fro your pleasure, dear fellows : 

 

 

 

 

 

 

 

 

Any pair of headphones that comes with a bottle of lube is... creepy.

Unipolar 2000 baffle without the acoustic filters.

 

 

The filter material.

 

 

The baffle filter as a whole seems quite an intricate system, but I'm not sure that I see a large difference in measurements between having the filters and not having them.

 

Also, and I'm sure MDR30 has noticed this as well, the way you need to bend the cable under the baffle is absolutely moronic. I can never get the bottom bit of the baffle to attach properly to the cup.
