Orthodynamic Roundup - Page 632

As for stretching the yh-100... I actually the headband from the yh-100 and frankensteined it with my qp55 ear cups and they pretty much seamlessly attached. Due to the circumaural cups, it naturally stretched the headband enough to be usable for a couple hours instead of 45 minutes. The phones are heavy enough that some clamping force gives me the comfort and security of knowing that it'll stay on my head even if i move around a bit.

I just finisehd a round of modding on my Yh-100...
Removed the thin felt layer and the foam layer
Put in a ring about 1.2 cm wide out of some material that Don handed me a while back. Without the drives screwed back in their housings I am getting great bass...well balanced across the freq range..

Where is the hot pictures??

Hmmm... the DK330 picture that Serge posted a long while ago suggested an open back, like the HOK. You don't think so? All four of the Dual orthos look similar on the photos I've seen.

One ebay seller tries to ride on the ortho popularity by promising "orthodynamic-like comfort" for a dynamic can ... But is that such a good thing to have?

Other than the T30, all of the Fostex are comfortable. The YH-100 is the most uncomfortable Yamaha. Some of the others aren't the best but I can still use them for hours, YHD-1 and HP-3. The HP-1 and HP-2 and the Audio Technica ATH-2 are comfortable. So all in all, for the commonly available orthos, more are comfortable than uncomfortable.

Since the YH-100 has tough vents to damp. Has anyone tried dropping the YH-100 drivers into a HP-1/YH-1?
(or is that just as tricky?)

I stand corrected, sorry! lol. I think this loaner HP-3 will be different as well to the other versions...It will have good treble extention and air, bass should be deep but not monsterous (this is in comparison to the bass heavy HP-3).

Also if Sachu was commenting upon your HP-50, I think your HP-50 is damped very hard and the primary layer is sealed right? So in that case it would be a very well damped scheme that has sharp transients.

The damping is subject to a final tune up this week. At the moment it is the Ludoo HP-50a scheme I think.
Best wait untill ludoo completes the scheme.
You interested?

How about micropore tape? I don't have an YH100, but still I wonder if anybody tried it? If nothing else, it should be easy to attach firmly over some vents. (or why would it not work?)

Question: If the voice coil is cut, would an ortho driver still work?

The HP-1 vents are on the back corner of the cup so they're easy to vent. The YH-100 vents are on the baffle side of the cup and the stock felt is about 1/8" shallower than the sides of the cup so you have to put something under the felt strips to raise them. Since I have thick felt, I just used that and it worked fine. It wasn't hard, I just didn't realize I needed to do it on my first damping attempt. It's not obvious when looking at the vents when everything is closed up. What clued me in was that I could see some of the blue tack.

For the felt lining the cup, I cut a disk slightly larger than the diameter of the cup. I cut notches for the screw posts and slits for the posts that hold the vent damping in place. I put this under the vent damping felt and the stock foam puck.

Edit: I'm interested just to see what the difference is. One request would be to send along a sample of the damping material so everyone knows how it's damped. We each have our own stocks of damping material. Even though some people have exchanged felts, I doubt that anyone has seen every type of material that people have been using.

I used micropore tape on the back of the YH-100's drivers. It works pretty well, but it still left a mid bass hump. I'm very satisfied with it. The hump isn't bad enough to make me want to try something else. It is the bassiest headphone I own, but I don't own what most people consider bass heavy headphones. Before the YH-100, my bassy headphones were SR-Gamma, HP-1, DT880, and K601 which are all around the same bass wise.

I'll take mine back apart and take pics tonight. I didn't take pics when I was doing it.

No , one of the SFI drivers I had was non functioning for this reason ..dB

Ok I'm rather suprised more people arent joining in the HP-3 loaner programme from here?
Wualta? Smeggy? Thought you two would have been on it (actually, i probably promised you already!! haha, so just remind me if ur in and ull be prioritised onto the list)

I might have been interested but a week is just too short of a time for me to be sure that I have enough time to just sit down and listen in my hectic schedule. Also the last thing I need is lust for more headphones. There's a problem when a man has around 15 headphones, and only about half of them work the way he wants them to (fully functional + modded "enough" if mods are necessary). And he has some amp projects he needs to start on/finish on top of that.

Well itll probably be at least a month or so untill it makes its way to the USA.
You can insert yourself somewhere you know you have time?

I'll have to consult Ludoo about the week thing...

hi guys, latest result about my diyOrtho's..

tryin' to bring out the staging, last night i change the cotton inside the cup with other material like thin felt + change cotton position inside...strangely i prefer before i use that felt, so i remove the felt and change back the cotton on serial position...then i use nippon tape to seal on the grills, now it have good intimate+involving staging...not as wide my K400 (offcourse) but much exist than before...ever look at Ultrasone's grill ? here's the pict, worth to try...
