CHART | Balanced Armature-Based In-Ear Monitors & Technical Characteristics - Page 5

post #61 of 128

Didn't mean at all to imply that the TWFK driver in a 3003i and a SM1 was the same unit, but just had similar properties. The range of headphones that use it for mids/highs is legion - and they all have their pecularities. Like a cook that starts with a common cut of beef, what he does with it (spices, heat, sides) makes it different to the taste than what the next cook would create. There was a bit of a row earlier where it was proposed that the SM1 was a single armature can that was being fed a split signal from a crossover. Your chart reflects the opposing view - that we have a flavor of TWFK inside. And as such, considering the high cost of the dual driver, the SM1 could be considered a value at its current pricing. 

 

That said, in the spirit of adding something to the above chart - you still show the TF10 as being in production. If I was supposed to PM that to you, I apologize.

The MSRP for the BA200 has changed to 300 from 250

Is it possible to add filter color codes for each driver where its possible ?

Good idea. It'll take some time though.

Amazing thread. Kudos to all who helped fill in this chart.

If I may say, the miracle uses a TWFK for highs, not a DFK..

It's not really an important point. A TWFK is merely a vented FK paired with an unvented WBFK. The FK and WBFK are essentially identical, except for armature stiffness and coil impedance, both affecting low frequency headroom. For the Miracle, I'd actually call it a "DWFK", which would be two WBFKs put together, but whatever, TWFK, DFK, DWFK, they're essentially the same. The important thing is the serial number that comes afterward, which helps identify coil impedance and vented/unvented character, but UM scratches those identifiers off their drivers.

DWFK actually stands for Dual Woofer FK - it based on two vented FK drivers. DFK is simply dual non-vented FK. DFK is only available in high impedance >100 Ohm.

Well that can basically change the sound by a big margin so it is actually important which driver is it. What's most important is though it's a type of damping.

 

I will be opening Miracles in a few days - I will be able to tell more.

piotrus-g would know better than me --- so please refer to his explanation :normal_smile :

I thought they came on sale about the same time.

Will be curious to know how it goes. Please update here smily_headphones1.gif

Will try - I have so much work to do...

 

For now I can upload a happy graph :)

Wow, that looks remarkably similar to how their own published graph looks...

I know ^^

 

The only problem is that it is measured as "shallow insertion depth" as acrylic IEMs are in most cases impossible to set properly in th coupler. At the reference point it would look quite different - smaller peak at highs

Yeah, I always thought those peaks were funky, because otherwise it'd be a miracle if anyone even bothered to listen to the Miracle.
