My computer died, which is why I've been away for as long as I have. I'm still updating items on my new computer. As quickly as I can, I'll post pics of the UM3X drivers. Brace yourself for a surprisingly unsurprising experience. Except for the crossover (which is a tiny resistor/cap attached to the TWFK), you're looking at our familiar TWFK/CI-22955 combo.
As for the filter, I share the headscratching about ohms, but that's how they rate the effectiveness of mechanical/cloth filters. Here they are at Microsonic 318, 319, 320, 321, 322, 323 - Knowles Acoustic Dampers
White = 680 ohms
Brown = 1000 ohms
Green = 1500 ohms
Red = 2200 ohms
Orange = 3300 ohms
Yellow = 4700 ohms
As the Ohm is the standard unit measuring electrical impedence, it's odd to find it used with a cloth filter, especially where the effect of the latter is to simply screen out certain frequencies - which is does mechanically, not electrically. That, however, is how the game is played. I didn't invent the rules. Like you, I just chuckle at them.
When it comes to sound signature, the best way to know what you're getting is to listen for yourself. I don't know how you'd factor in these numbers. This combination of electronic and mechanical factors in producing a final sound is something that has been described as being as much art as science. On the other hand, the exciting news is that most of the sound sculpting is done with cloth filters, which can be swapped in and out. If you don't like the sound of your UM3X or SE530 or ER4P or HF10, you can change it. You don't have to wait for a manufacturer to get around to meeting your needs. THAT'S what I call customizing.

The TWFK is a wide-range driver with amazingly flat response throughout. It doesn't emphasize any bandwidth, which is why you'd want an additional driver if you want killer bass, but this driver is no slouch when it comes to representing mids. I'd think that the best driver choice would be the one with the flattest response overall. The TWFK is an expensive driver and well worth it. I wouldn't use a different driver for mids unless I had a need to spike the mids, which I don't.

There are several ways you can go with cables. Westone and Ultimate Ears both sell stock replacement cables on their websites. Westone gives you one version while Ultimate Ears has higher and lower versions. You can also make your own cables, using 28 UAW wire, though it's more work, doesn't look as nice and still requires you to come up with connectors.
Hey Bill, could you upload high res/closeup pics of the um3x's internals? And when you say 680ohm filter are you talking about a physical filter or an electronic one? I'm having a hard time understanding how it could have a 680 ohm filter(electronically that is). |

what can you recommend if i want foward vocals? more mid? btw can we configure TWFK as mids? |

Hey, it might have been addressed, but where are you getting the cables and what kind? I saw one post with Westone's cable, but wondered about alternatives. I'm really interested in a project like this, and perhaps scavenging cases and other parts to load with custom internals to tweak, and maybe to replace the cables on my e3 one day. |
