Thanks very much for taking the time to post a detailed '101' on the topic, tomscy2000.
 
I find it particularly intriguing that, in contrast to almost all his peers, Grzegorz has produced something as complex as the SE-5 without resorting to the use of filters. Very impressive achievement, IMO.

Thanks for the explanation is there sonion alternative to the ka twfk and cl22955? That will fit in the se535/e5c shell? In a nutshell im going for westone 3/um3x clone

It's a combination of tube length and diameter plus phase shifts. ACS also made its IEMs without dampers back in the days.

2091+2323 could be made to match Westone 3 or UM3x response. There's no straight replacement for TWFK in Sonion line up.

 

[Nyanman]

but a cl22955 and twfk will be better? i'm really just exploring my options.How do i use sound tubes to modify the sound? what acoustic dampers/filters do you suggest i use to achieve the westone 3 sound?

 

[AudioNoob]

Is there a way to identify (without model numbers) which driver is doing what? My ciems have a small dual armature, and another single armature at least three times as large, I can only read the large one, which is a knowles 22955

 

[MuZo2]

22955 is for bass and small one for mid-highs.What iem do you have.

 

[AudioNoob]

They were superfreqs, they just got reshelled by inearz and I am trying to figure out why they sound a little veiled.

I'm not exactly trying to make my own IEMs, but I see that the topic of drivers are being discussed, would anyone be able to give me their opinions about this?

I'm trying to combine the drivers of the SM3 and TF10 into a reshell, and am looking for more opinions.

I don't think it's worth it, but the most plausible thing would be to use the CI low driver from the SM3 and add it to the TF10. However, it's much cheaper if you just ordered the CI driver online, instead of destroying a perfectly good earphone for no reason. It's not practical to add the mids and highs of the SM3 to the mix, as they are delivered by a single dual receiver, the TWFK, and it doesn't quite fit in with the rest of the crowd. However, I've had a TWFK + 33A before, so that's plausible as well. The 2389 (UE-High) of the TF10 can also be added to the CI low of the SM3 for a dual driver configuration, but somehow I don't think you're interested in making two earphones by mixing and matching one another. Also, most companies won't be willing to do this for you, as they don't want to take the time investigating how to best implement the crossover. They usually have set formulas, like the TF10x4, TF10x6, SM3x8, etc. I advise you not to try this.

I follow your line of thinking, but I also think this is a bad idea.  There's no telling how those drivers will sound in the same shell.  At least with the known options there is a known outcome thats sounds good.  If you wanted to add drivers to a universal iem, I think you'd be better off going with tfx6, or sm3x8, but even then there aren't that many people who have done that.  Probably better idea is just to go with the customs that already have pre-configured set up ie Miracle, Merlin, etc

I see, thanks for everyone's inputs! I saw tf10s that needed to be reshelled for a good price, and I already had the sm3, so I was curious.

Hi all, 
 
Just writing a post to say the drivers I'm selling are having a little discount on them! They were listed at £110 but I can cut it down to £90. I can post to USA for all you people asking! These are SONION drivers.
 
 
If anyone is interested I have just been sent some sample Sonion AcuPass Drivers which are a a two way driver and include an internal crossover. here is a link to the website announcing them
 
 
http://www.colsanmicro.com/product-release-1723-acupass-2/
 
Let me know if anyone is interested in them!
 
Jack

Allow me to clear things up you are trying to actually sell AcuPass drivers you've received for free?

 

[jackpawsey]

They weren't free i'm afraid!
