That's what I said before isn't it? :P
I remember a low pass acoustic filter is a narrow tube with larger chambers along the way, so the Penta probably has acoustic low pass for its bass drivers.
You really can't compare to that graph though, the peak shifts with different tubes length, material, and diameter.
3800 is louder in the lower regions and has a huge vent. If I use the 3800 I'll have to stick resistors on it since the bass is much too boomy for my tastes.
Does the 3700 series have a noticeable bass boost compared to the 3300 series?   Also, can't the bass drivers be smoothed with resistors? The CI driver smooths really nicely with the 28ohm resistor.
Most of the ones I asked were out of stock actually, despite them being shown as in stock.
 Taobao's 33A007 are sold out :\ Only have the 33AE011 left...Their 3800s are only available in larger quantities too. 
Wow they look excellent! How did you get the words on there? 
 I thought the CI's graph looked better on the low end?
Has anyone here tried a high frequency driver that they liked more than the ED29689/ 2389?
