on the homemade wooden cups, is that a center hole for a live center?
or is it a hole that goes all the way through the wood?
Working on building them over winter break, will post pics

The hole goes through. It can function as a vent which you can (partly) block or seal completely, depending on your preferences and on the impact that the (p)leather pads have on the sound. I found that I preferred my setups with completely sealed holes. This results in a more neutral response, which I prefer.

Closed Paduaks...need to work on leather pads now...

 

[stratocaster]

These look great! But as you said, you need some (p)leather pads.

 

[fleasbaby]

Indeed. The plan is to get some of those cheaper Ear-Zonks and find some pleather. I think I can figure out the wrapping from past pictures in the thread. What glue did you use that didn't eat the foam?

 

[stratocaster]

Just plain leather glue

Is there any way to increase the bass output? Different driver, more felt, felt between driver and earpads?

 

[stratocaster]

The leatherized bowl pads (L-cush) increase the bass output to the degree I find suitable to achieve a neutral sound signature. KSC-75 bass is not the fastest/tightest anyway. If you boost the bass further, the balance would be gone and distortion would become a real issue.

Ah okay. Thank you. Does anyone happen to have any measurements of the cup requirements? I might have someone that could make wooden cups, but they are obviously in need of measurements first.

 

[stratocaster]

Koss KSC-75 outer diameter:44mm (without black foam)
--> Cup inner diameter should be 45-46mm.

 

[Nimzerz]

Thank you so much.

Just making sure, all of the steps on this thread are updated, right? Any recommendations for wood types? Where I should go about getting the wood?

 

[stratocaster]

Yes, there are no updates.
 
Do not worry about the wood types. As 'important' as the cable
The really important thing is the (p)leather pads. Naked Grado foam pads sound awful on these.

Do you think sealing the ear-side (or whole outside) surface with silicone or latex could work?

 

[stratocaster]

Don't know, but I wouldn't want to have that material touch my ears. Using leather is best, IMHO. Did not have best results with velour, leather works best.

My latest StratoKOSSter build. Used HM5 pads this time.
The pic also compares Sennheiser Momentum and StratoKOSSter (with leatherized Grado L-pads) measurements. Quite similar, but  the treble is less rolled off in the Stratos.
