Let me rephrase then, which measurements does modular use? If u dont mind answering since his look uniform.

Also, i am new posting to this thread, but i went through 450+pages of reading (awesome thread) on the he-400. Really seems like jerg got the best of both pads

I measure it by eye actually, but it's not hard to do.  Try this diagram I just quickly did up in Paint:

 

Once the pad is inside out, you'll see the 4 stock damping holes, which you can use as reference.   I use a permanent marker to mark the points.  You can use a ruler, but I've done it so many times I can just do it without now tongue.gif

 

So mark points in the center from edge to edge, equidistant from each stock hole, then repeat between those points:

Next, you'll do two rows, each closer to the edges, in between the middle holes like so:

Once they are all plotted out, you can begin cutting or you can trace out the hole plan first.  The middle holes should be bigger, and the outer ones smaller, like this:

Just repeat all the way around and you should be good!  For your first time, definitely trace the holes out before cutting.

 

Edit:

 

Here is a pic of a pair done so you get a better idea:

Personally I like to trim the two smaller rows of holes a tad larger (especially the inner row), but that's just my preference when I mod, there is no definitive sound improvements I observed over cutting smaller holes.

 

I guess for the outer "port holes" (that's a good name for them right? We can call em that from now on tongue.gif) that I've been discussing with you, they can just be lined up with the larger damping holes, just cut 16 out; then cut another 16, offset by half the distance between the first 16 holes and a little lower.

 

Or if you wanna save on time, you could just cut 16 large vertically oval holes.

 

It's pretty cool how the velour shell variation of the velour top mod you thought up, meshes absolutely perfectly for this potential new addition for the jergpad list of mods.

Thanks

Yeah, I realize that picture is from my very first pair in which I ended up making the holes a bit bigger.  Larger, more vertical oval holes may not be a bad idea...instead of the third row.  I'll be trying out that new step as discussed in the next few days... wink.gif

Oh no I meant the vertical oval holes as an option for the outer port holes, as opposed to 32 medium-sized circular port holes.

 

But I do agree that doing something similar for the inner damping holes would be good too, if it boosts your efficiency.

Ah, gotcha.  Makes more sense on the outer portion.  We'll see if I can switch it up a bit, but I'll keep durability in mind as well.

Durability is always a compromising factor to consider. Ideally what works best for retaining fabric/pleather integrity would probably be very small (<5mm diameter) holes evenly spaced out and in a checkered pattern, but obviously that is not feasible to do except during manufacturing of the earpads.

Hi. What is the diameter of the plastic ring attached to the stock pads? Thanks
post #911 of 1674

Returned from vacation and tried to he500 the jerg pads modulor had sent me some weeks back.

I had initially some difficulty with fitting them to the drivers (the velour cover got out of place), but fortunately my wife is handier than me.

First impression (related to the velours): somewhat warmer and more natural sound to my ears, not muffled at all (leathers were a little muffled for me). Not night and day difference, but easily detectable - and appreciated.

Really well done by jerg and modulor, thank you to both.

Just came back from vacation and discovered the amazing work Modulor has done here. I can't believe I missed that first batch, I'd been waiting for someone to make those ideal pads with a better level of quality and esthetics than I could ever pull off...

 

Anyway, I've already sent Modulor a PM; I definitely need to be on the list for that second batch lol!

 

Great work people, seriously. Even the first version of the jergpads was already quite a welcome improvement, but this current all-inclusive mod is just amazing.

In my opinion Modulor's work, with potentially another big modification step him and I are planning, could very deservingly be the next evolution passing v2.0.

Am all ears now..do the batch one owners get a discount if we decide to get the modulor v3 pads also? biggrin.gif
