iirc, I ended up using the dense scheme myself ..dB

Clamp as in the headband clamp? I think they are similarish between 50S and HP-3. If anything HP-3 is slightly less clampy.

If your talking about the baffle clips, I concur that my 50S clips automatically clip into place, while the HP-3 requires me to manually clip it.

As for my scheme. Yes the polyester discs are less dense than the felt, but I am using 4 of them (not 3). And it seems to be able to damp the 50S, which is something the Bass heavy scheme could not. So I deduced from this that my scheme is denser.
The reason I used this material, is that it still allows air through in a diminished way, and is v.thin. So I used them as 'tuning' discs. Because I got to the stage where I ran out of space to use more of Ludo's current material arsenal.

In other news, I removed the moorbrook layer from my Aiwa damping scheme, and that seems to be better than before, its slightly underdamped now, but maybe a blob of fibrefill to fill the cup recess and I think i'll be more than satisfied with it.

Or maybe Ill reinstate the second 'biscuit'.

Also of interest; the thick 'Smeggy Felt' looks very similar to the stock felt that is used on the B&O U70.

As for the nickname "biscuit", I should note for those of you in the UK that what you think of as a biscuit, we in the Commonwealth of Michigan think of as a hockey puck. The "biscuit" in the Fostex, Stax and Audio-Technica 'phones is soft like a scone made of yummy mineral wool. Fluffy and nicely absorptive of mids and highs, and with little acoustic resistance.

If you're ever in the American south, ask for biscuits and gravy (ask anywhere, including bus stations and machine shops) and you'll get big fluffy buttermilk sconoids that will remind you very much of the headphone variety. You might be tempted to stuff them in your pockets to take home to your HP-3, but the gravy will upset the balance of the sound and onlooking southerners will shake their heads at your quaint Old World customs.

Curses! I forgot today was Veteran's Day, so the package will go out tomorrow, sorry!

I actually prefer the stock YH-1/HP-1 to the stock YH-100. I find the YH-100 very dark. However I agree there are certainly hints of what greatness lurks in those drivers.

Modded properly however the YH-100 is a much nicer headphone IMO due to the extended bass responce. I like the YH-100 frame better too, not that I ever use them.

Oh man you're making me hungry wualta! When I make biscuits and gravy I add a lot of pork sausage to the gravy. Yummy!

Allthough the Brits have a similar dish in Yorkshire Pudding, or Batter Pudding as my Ipswitch friend called it. If you've not had it you're missing out on a treat.

I'm now craving biscuits, of both the sconoidal and wooly variety. My hunger shall never be satiated, only mitigated and delayed for a small, arbitrary amount of time, one at a time. It is a problem I myself can overcome, for myself, with myself, through mine own determination and willpower only.

I'll pass on the gravy, most of the time.

Also, curse my love-hate relationship with both Ebay and Fostex (they are not and never were mutually exclusive, so cheating is not a possibility). I can't resist purchasing a T50RP for long...

Edit: That was fast. 2 are already sold.

I was actually referring to headband clamp.

Here is the gap I was talking about earlier

Mine are flush - mostly likely less damping to push back up..dB

Preheat oven to 425f

sift together:

1 cup of all-purpose flour
1/2 teaspoon of salt
1 teaspoon of sugar
2 teaspoons of baking powder (non-sulfate preferred)
1/4 teaspoon cream of tartar (if you've got it, or you're shopping anyway)

Chip or grate in 1/4 cup (1/2 stick) of hard, frozen butter. For best results, anyway. cut in room temperature butter for a more, shall we say, KFC level of texture.

Using a dinner fork, mix in 1/2 cup of milk. The fork is an inefficient tool for this job, and that's the point. A better tool would allow you to easily overwork the dough.

Dough should be very sticky but not loose, and have little chunks of butter in it.

Sprinkle your clean work surface liberally with flour and dump the dough out onto it. Assure that the dough is sprinkled with enough flour to handle it.

Flatten to 3/4" thick, fold in half with the rough edges at the center, flatten again, invert and rotate 90 degrees, fold in half again, flatten, invert, and cut into four to six squares with a sharp knife.

Bake on an ungreased non-teflon non-insulated metallic baking sheet until lightly browned on top.

Something like 12 minutes. Long enough to ease over an egg or two if you strategically started warming up a cast iron griddle before adding the milk.

(headphones are not my only hobby)

(this is not so much my own recipe as it is my own adaptation of and process methodology for the recipe i grew up with, which has origins both obscure and banal, and which had a few flaws i've corrected)

(This is, near as i can tell, a northern biscuit. if you prefer southern biscuits, buy a bag of white lilly self-rising flour (accept no substitutes - southern flour is inferior in ways that are advantageous for southern biscuits) and follow the recipe on the back of the bag)

Yes, but will the biscuits make the orthos sound better as well as taste better?

So, my lathe chuck in in and working wonderfully, plus my lathe will now work as a disc or drum sander, rotary file, grinder and myriad other things as the chuck closes to under 1/4" which just happens to be what all my drill attachments are

Being able to use all these with a nice sturdy tool rest will be awesome. Next I need to get a chuck arbor for the rear end so I can use it as a Drill too.

Sweet!

You are a God, ericj. What of, I'm not quite sure yet.

I thought that was the point. Gravy... not so much. Of either, really.

Hey, I shipped you the Pro 30, SR-5 ear pads, a check and a midget named Norm who can pull out your splinters when you are working with the woodies

Expect them by the weekend, unless Norm escapes...

Well I finally got off my biscuit and repaired my broken Concept Ce-h headphone. I had purchased a sick pair of Fostex T20s from a head-fier and simply removed one of the voice coil and replaced the fried one form the Concept. The transplant seems like it's being accepted quite well.

 

[smeggy]

That Norm sounds like a feisty wee fella, Is he self-sufficient or will I need to feed and water him occasionally?

NO, he's like the gnomes in Harry Potter that fend for themselves. Norm the gnome.
