Orthodynamic Roundup - Page 1522

post #22816 of 23377
indeed, and i refer to that statement about Senn's hasn't produce a planar bla bla bla..
planar can be static&tret as well..

if the statements are "Senn's hasn't produce an orthodynamic in their entire history of Hi-Fi." then i would not make any argue at all...wink.gif

And outside of headfi, "ortho" will make people think of teeth (or possibly feet/insoles).

do have those sony biocellulose drivers already.

 

I'm sure everybody already heard on the Sony MDR-R10, i was reading about them yesterday and seem like they were pretty advanced for it's time using Carbon Fiber, BioCellulose and other materials that still not found on many headphones, even top of the line models, but they were dynamic, right? the driver design they produced don't look like any orthodyanmic or eletrostatic headphone i've ver seen.

that was offtopic - we were talking about r10 cups (open sounding closed design), but drivers are dynamic.

 Have you got some picture of the that ear cup the the Sony R10? i can't find that much information about this headphone, and while i was reading a review about it from 1989, i heard about that legendary open sounding close back design, but never got a picture of it on the inside.

try this first.

google finds plenty of images easily, by the way:)

and there is nothing extraordinary - sennheiser type delayed pseudo reverb mainly.

Yep, it's a fairly simple design, sadly, they are pretty rare headphones and only few people will have the chance to listen to them, would be nice if they made a similar model using orthodynamic drivers, maybe they could sound even better.

are you serious? it's very expensive to make something good now, none of business- money-profit oriented company is interested in such things. this is not rare:

Wow, these headphones look pretty amazing, the price is also amazing, now imagine if they were orthodynamic headphones...

thank you. i suspect this thread and wualta personally ignited ortho revival, no less. and - not only cups - earpads are equally important, and traditional donuts are really not my

taste. few random pictures - earpads are gradually damped too, no internal reflections and really comfortable

.

Impressive work. Whats the different materials used here. Also would be interesting to see wood internal damping materials. Are you sound engineer, how did you come up with those designs for cups and pads?

1st picture - opencell foam, layer of memoryfoam on top, soft felt inside, layer of soft  felt outside for damping and leather with some perforation at strategic points outside. second - outer part is made of hard felt. so it's plenty of air in front chamber, but springy and no reflections. all the needed bass, airy highs, good sealing and no "pumping". damping in the cups - all kinds of felt, chopped when labyrinth is needed, loose wool and melamine for reflection canceling. and some geometry here. drawing ideas for designs is a part of my morning tea ritual, and it's every morning - so there are inexaustible resources in my drawing book. and i read a lot. can't  cover everything in one post.

That's impressive, could you share some of your ideas with us? i guess this could help everyone.
