I remember it being mentioned that the the 2000 series is slightly smaller than the CI right? I'm thinking about a good choice of woofer to add to my TWFK + 3300 combination, and I'm beginning to have doubts that the CI will fit in my small-sized shells, especially with the 33A007 already in place. So... 2015, 2028, 2091i?

33A007 is a woofer why do you need additional one.
CI 9.47mm x 7.18mm x 4.10mm 
 
2000 9.53mm x 7.24mm x 4.14mm
It would be difficult to fit 33A007 + CI or 2000 if you are not planning custom shells

It'll be a sub-bass boosting woofer, coming online only below 50-80 Hz. It is a custom shell; I just have small ears.

Yeah, 2000 is actaully bigger one
 
3300+CI +TWFK will be easy to fit. So no worries. CI is a great woofer and lower mid-range driver. It has pretty liquid mids. I heard to two opinions on 2000 one saying it's a great woofer but not mid-woofer and second that it's great mid-woofer but there are better low-drivers. So I can't tell you much about that driver. It probably all comes down to preferences
 
2015, 2028, 2091i - it all up to you. It depends on your aim and there's more than one anwser to the question which suits you more.

You haven't seen my ears!

I do think that it might fit, just a little dangerous.

Lows- Knowles CI, Sonion 3300, Sonion 2015, Sonion 2028 (The CI, 2015 and 2028 are the most powerful, while the 3300 goes the lowest)
Also, the output of the 2015 is far greater than both the 3300 and the 3700. Sonion says the output of Dual 2015's would be equal to about Three 3300 (9 armatures). So these are powerful drivers.

3300+CI +TWFK would be Westone 3 with additional 3300 driver.

But it's not wired like a W3! The 3300 would be used mainly as a mid/low driver, rather than a subwoofer. I'm trying to use the CI as a subwoofer.

And it's good thing to do. And no I have not seen your ears, but let me tell you TWFK is CIC driver for a reason
 
Speaking of your ear capacity how you even did come up with the idea of the project we were discussing over PM? :O

I am wondering where do I get filter replacement tool for sonion filters.

 

[tony-pro]

Please Help, does this look alright?
 

 

[MuZo2]

 Is this something from speaker design sw ?
139 ohms series resistor seems bit high , may be you can consider acoustic low pass filter & reduce the resistor value. May be the sonion expert we have here can give us more suggestions.

No, It's from a circuit design software called tinycad (open source). The reason I put the 1st resistor up so high is because when I wire the drivers in parallel, the impedance drop is huge. I'm going for ~ 30 Ohms of impedance on this circuit ... however that's 30 Ohms and 1KHz. I am attempting to go with a Damper-less design.

Damperless design not easy

Can you explain why?

Hi,was wondering if Knowles Acoustics Drivers come in pairs or singly?Eg. when ordering from Digi-key,did they send 2 drivers for both the left and right channels when ordering for 1 quantity?Is it $62.58 for 1 driver or 2 drivers in this link,http://www.digikey.sg/scripts/DKSearch/dksus.dll?Detail&itemSeq=114236233&uq=634719045856563557 ?
