Someone have a set of bellsing 10013 for sale OR know how to get Them?
Soundlink still sell them in china i think they send you some when you ask (and dont live in the us i think)

Hey,
Does any one know a good Tipp to get a few dB more at 3khz? Without changing drivers.

What's the driver combination? Looks pretty good.

HODVTEC, Bellsing Twfk, ED

They allread sound amazing tbh, but I think just a tad more at 3khz would be great.


What do you mean by "tip sensitive"?

Can you change the damper or XO?

Hey guys, I've been building the finale 2 IEM in a universal fit shell. When test hearing it sounds rather shouty. I was wondering if I'd have to adjust tube length due to the fact that I'm using a universal fit, cheers
Your ED30761 looks like full covered. The vent looks closed off

This will cause the bass to die and make mids more prominent

Plus... There was no components in the iem... If I remember correctly.

The driver isn't fully closed off. However I don't know where the vent is when looking at the driver and schematics provided by Knowles. Is it on the back? If so then it shouldn't be an issue as it isn't covered.

If you're referring to the two resistors: those are two 1ohm resistors. The design calls for 1 2ohm resistor.

Cheers

Pads, if it's a mistake (I see two open pads), can cause asymmetrical peaks. You should also close the shell to compensate the chamber pressure.

Ohhh the minor compensator I called for.


The issue of shoutiness is due to covering of vent
