Orthodynamic Roundup - Page 1502

post #22516 of 23459
Hmm, finally tried this felt (wool? foolt) piece from a winter coat that a local orthomodder gave me to mod my YH1. IIRC he said that to use just that inside and replace all of the stock damping. Well, not confident on how well they will stay put when I put everything back together, I lined the cup with those thin generic foam sheets, and then the foolt pieces.

Hmm is all I can say right now. TBH I don't know what I'm aiming for with the mod for now. For a long time I like the stock YH1 sound, but I just felt my hands itching to try this out.

It's the older parts of the city being hit the hardest. I'm in a medium age neighbourhood and so far we've been fortunate. There was a break a couple days ago two streets over, but nothing serious has affected me yet (the occasional brown/silt in the water, but nothing affecting us for more than an hour tops). The central areas are getting hit hardest. Over 900 water main breaks so far, both city and residential lines. We'll probably hit 1000 by the end of the week.

 

Ironically, the (very slow) spring thaw is actually making things worse since the water seeping down chills the ground faster, so the rate of pipe ruptures is actually going to increase :blink:.

 

I'm actually just about to head out to buy some water jugs in case we lose our water.

Can you describe what it sounds like now at all , no fancy schmancy woids necessary just the "beef". What do you feel is wrong or  missing at all?

 

Armaegis that is a good thing to hear, when i heard about it all going down i thought about your place right away. Yikes.

Winnipeg is just having a brutal winter. One of the coldest in recent history, the old plumbing infrastructure is getting destroyed by the frost, the potholes are ridiculous right now, made worse by the flooded streets so you can't even see them then wind up crushing your car into one. I've done so much shoveling this season that I have a small mountain range in my yard... seriously. Three hills, the largest of which is maybe 8 feet high, because I can literally walk up into my tree from it.

 

But at least I have running water, which is better than the hundreds (thousands?) of homes right now which don't.

Well, there's something odd with the treble. It's not really grating or anything, but it just feels odd. Detail retrieval seems to improve, but I suspect that's because of the odd treble. Bass kind of tuned down a bit overall, but midbass sounds more boomy now. Female vocals is more veiled than stock, but male vocals seem to be clearer now. It's odd, and I don't really like it.

Try getting rid of the foam pieces ( is it the dense thin stuff or regular foam ) to let the bass breathe and get damped by the rear felt stuff only. That foam might be messing with things. Or just use one small disc enough to cover the rear cup hanger indent there  and keep it away from the perimeter vents. If bass is too boomy then  double up on the perimeter vent felts maybe.

 

just some ideas.

Here's my re-cabled HP-50A. I used the stock wires from the Left cup to the Right cup.

 

Kapton Gold looks nice with these headphones.

 

I damped with the stock open cell foam and a disk of 4 mm dense, soft wool felt. Sounds great.

 

Thanks nick n!

 

No screws. Snap tabs hold the baffle to the cup.

 

Stock open cell foam damping. That's it.

 

Left channel on left; Right channel on right. Stock Mono wiring.

 

Re-cabled for stereo with navships (ebay seller) using 26 AWG

Kapton insulated SPC multi-stranded wire - 4 wires are braided.

 

Thick (4mm) dense, soft wool felt damping over stock open

cell foam on the inside. It was a tight fit with the felt and

larger wires.

 

 

The Kapton wire is microphonic so I'll be looking for a soft

sheath.

 

Pads are in great shape. They're secured with double-sided

tape cut from a large sheet. The tape seals the access 

openings for the snap tabs.

Nice work.

 

How I wish they had used that headband covering on the other Yama's:triportsad:

I'm in need of a single Yamaha HP-1 driver.  One side of a set I have was DOA, otherwise this set looks real good.

 

PM if you have one you don't need.

 

Thanks

post #22525 of 23459

BMF i did manage to find, on a side note... 3M Micropore tape here in Canada. Not as wide as what i got before :)  but it is labeled as paper Tape, and only says Micropore inside the tube it is on.

 

Hope you run across something for the driver there. Bound to be one around.

How are you finding the high end on these?

 And speed or decay?

 

 

Also anyone else with theirs around and handy please chime in here. Of course all are going to be slightly different.

Wondering about  tuning towards a tighter decay or presentation on the next. or at least what the limit is there before it affects the rest of what is fantastic about them, let's call it the OUTER LIMITS.

Thinking about what  used in the final T50rp's and adapting it to here.Theoretically it should work. Think like a driver. Think like sound..:popcorn: NOT that they are poor in overall sound quality, just making more trouble for myself here I suspect.

 

And i should mention what other people are probably thinking "DAT CABLE!!!!" veeery nice

 

EDIT : nearly forgot to ask this is important. Was there a white paper damper in there and did you replace it or remove it if so?

A little extra damping helps tighten the bass which brings out more treble details; I would actually like a bit more treble. The mids are very nice. Speed is average after felt damping but this was a "one off" tuning trial. I'll try a few other things when I have time.

 

Yes, there are white "paper" discs between the ear side of the drivers and baffle dust covers. I did not remove them but will try without the next time I open them.

Does anyone have any YHD-1 drivers? I would like to try transplanting them into a Pickering OA-7 chassis.

Yamaha YH-1 Modification

 

The first picture shows what did Not work.

 

 

Pictures 2-4 show what Does work:

 

The SQ is really nice from top to bottom of the FR.

Lots of Fast bass with good extension.

Clear, lush mids with No Boomy Bass Bloat (B3).

Lots of treble details/shimmer without sibilance.

 

 

This Did Not Work:

 

30 mm Paxmate Disc in Cup Floor Under Stock Open

Cell Foam. This created too much damping pressure

against the back of the driver that squashed the bass.

 

 

This Does Work:

 

Paxmate Ring on Cup Floor with Fiberglass Disc inside.

 

Note: I removed both layers of Stock Perimeter Felt so

the rear slots are fully open. The back wave vents from

the sides of the damping stack.

 

 

nick n's secret sauce over Paxmate Ring and Fiberglass Disc

on Cup Floor.

 

 

YH-1 Stock Open Cell Foam over Paxmate Ring and

Fiberglass Disc on the Cup Floors.

 

EDIT: Fiberglass has never bothered me. In this case, I don't know if it adds anything to the SQ since I did not try this configuration without it. I've used a thin layer of cotton extracted from a make-up remover pad with similar results. Angel Hair may work, too. 

 

I failed to mention that I placed a layer of gauze under the fiberglass. The fiberglass is effectively sandwiched between the gauze and the white felt + stock yellow open cell foam and contained within the Paxmate Ring so it isn't going anywhere. As shown in the 3rd and 4th pictures, I removed both layers of the stock black felt segments exposing open rear cup vents. The back wave vents through from the sides of the damping stack and then out the rear cup vents (slots).

 

The SQ from this YH-1 modification is some of the best I've heard and comes close when directly compared with current production planars. I doubt that I will open them, again. I'm going to try this same damping stack in the HP-50A.

hey wow I think I used a similar setup!

 

Will have to check the notebook. I know for sure I used the "secret sauce" and possibly some orientation of similar foam. each time I put them on I keep remembering what they were like stock and expecting that somehow, but each time I am pleasantly surprised with the great response all across the FR, and not a boomy thing either, rather fast. "Secret sauce" is almost the go-to ( either version ) for anything I try now it seems pretty versatile, with some actual repeatable effects depending on a given arrangement.

 

thanks for the posts

 

*could very well be a pinch of Angel Hair where you have that fibreglass even!
