Nice work Bill with the new toy.
I like both designs albeit pine doesn't look like it will be a big seller lol, but it's enough to get the picture and much cheaper to make mistakes with
 
The GS looks nicer if the added weight is insignificant. I also quite like the way the mesh fits into the whole picture.

Bill, those new pictures are making me itch to get my cans back! I really can't wait to see my shells, your work is looking awesome. Also, I have made a good amount of organic body jewelry with a lathe before so I might be able to help with any questions, etc. My lathe was stolen from my garage a few months ago, or else I would join in on the shell making awesomeness in here. I'll get one again soon, haha.

I have to disagree! I've been an amateur sawdust maker for many years and I love the look (and smell) of pine. The first thing I thought when I say Bill's samples was, "Hey, pine would be a cool -- albeit unusual -- choice for cups!" The real problem with using pine is that it's a soft wood and would require lots of attention in terms of applying a protective topcoat...
 
Me likey! But that's just me.

My problem with pine would be if you dropped your headphones are even bumped them against something, you'd probably be left with a big ol' dent in your shell. Pine is just too soft. If it's not seasoned right, you might also deal with cracking, shrinking, splitting, etc.
 
However, that said, pine is slightly bright, resonant, has a good all around response and is cheap as dirt. Some of the best telecasters ever made were made from pine. I built a guitar body for a friend a few years ago from two pieces of pine I bought for $8 at Lowes and it sounded wonderful, but dented very easily. You could see anywhere it was ever dropped or scratched at all, but that made for good memories of good times, haha.

So now I've got the Dynamat . Has there been any general consensus about where and how much Dynamat has the best affect on sound .
 
And the same question for the number of holes . I realize this to sum extent will be about personal choice but there must be some limit of either having too much or too less holes and Dynamat .
 
With the Dynamat I can add and remove until I have found the balance that sounds best ,though I don't have any felt so don't really want to punch anymore holes as yet .
 
So what experience have people got with SR80i's , the balance of a 4 hole shell & Dynamat ?

Venting = improved clarity + a more defined bass .
 
The shells came apart very smoothly after about 5 minutes of steam .
 
Initially I cut out two holes on one side and left the other as it was . I loaded up a music production program and Got a Bass drum , kick and snare playing  & sent a mono signal to the headphones .I was   blind testing to make sure that placebo wasn't driving my decision making process. I  kept swapping the headphone shells  around so I did not know which one had been vented(The only way I could tell  was by shinning a torch through the back of the shell).
 
On the first few listens I was certain which sounded best and correctly choose the vented shell.Though after further tests I could only detect a trace of something different between each driver,  it wasn't significant enough for me to accurate choose the vented shell .
 
So I decided to go for 4 holes thinking I'd cover them up with masking tape if I disliked any results . And that extra 2 holes made a clear &  noticeable improvement  of the overall performance of the vented shell . The bass was extended and more dynamic .The vented shell had a far more responsive attack, Decay ,Sustain and release of the Drums.The Slightly sibilant highs had become less noticeable as there volume was more balanced with the lows.Individual Rhythms were far more clearly focused as they had found more space to play .
 
More Thud but not Mud .Less Glare and more sparkle . << for the technically  learned .
 
I kept swapping the shells over randomly and it sounded 'clear' which was the vented shell . It was easy to tell the difference between the vented and non vented on my SR80i's .
So both shells now have 4 holes in each .whoa! I can really connect with these now.

 
 
 
.If anyone  does not hear the difference between vented and a non vented shell , try the feeling approach .
 
Listen to some music with Drums and Bass with a Fast Attack and release as they offer the most instant power .Close you eyes and focus on the  vibration.Feel the pressure waves increasing and decreasing in the inner ear.
 
The vented driver "pumps" more

  . And it is a defined pump not a irregular OmphHHHhhhhh.
 


Thanks for the Tips Bilavideo and company

SR80i you said?
 
I punched all 8 holes and the bass feels too bloated, IMO, its just too much for me, but i am not a basshead. I havent cover the wholes back, But i will be doing that soon

Glad to hear it worked out for you!
 



I'll post pics of what I did with my dynamat. You can actually poke two holes with a small screwdriver to leave the magnet vented.  I've got 8 holes poked in my grado's and they sound balanced to me with the dynamat.


Do you have dynamat on them?

Just drop $80 and pick up a new pair of SR60i Grados.  Most of the used Grados don't usually sell for very much of a discount.
