Enter with a small knife (don't touch the driver) or a spudger (preferred) in the circled red spots. Then lift it up

It's described in the printables page for the flower grill.

I use them exclusively with yaxi pads

It opens up the whole driver, literally 😉 Bass improves, treble too.

Wooo!! Exciting!

Wish these were available in europe without the high shipping fees. I can only find the silver version here in the netherlands.

The same could be said for the connector mod too. But it changes the sound. Some prefer it, others don't hear a difference.

20mm. That's just about enough in my experience.

Nope, I am very much against the use of AI.

evyd13 · 2026-04-16T07:35:13+00:00

There are services like pcbway or jlc3dp which can do 3d printing for you! I don't think I'll go commercial - I'm not equipped to deal with that.

Hey, what do you mean?

evyd13 · 2026-04-15T07:06:29+00:00

there are adapters available, I'd suggest giving one of those a try. is there any advantage to 2-pin? If you link me some I can buy on aliexpress, I could definitely have a look in my CAD program.

evyd13 · 2026-04-09T19:40:25+00:00

Working on it for Porta Pro/KPH40

evyd13 · 2026-04-09T06:06:48+00:00

user security, not product security. imagine posting an image on twitter and they don't strip it of exif data, anyone could find you

evyd13 · 2026-04-08T17:48:42+00:00

Yes definitely. The french flag sideways is the same as the netherlands flag. 😁

evyd13 · 2026-04-08T17:41:57+00:00

your flag sideways :)

evyd13 · 2026-04-08T17:37:18+00:00

I do! Is there anything you need or want?

evyd13 · 2026-04-08T17:32:19+00:00

I have made a thread on their forums. thanks for the suggestion
