My sincerest apologies. Thanks for your understanding. I'll remove that portion. Thanks for the update. Got it with the ferrofluid. It does find home.smile.gif

About GQ: there are two models. One seems like what you'd expect from a normal armature, the other, not so much. :-)

Who knows if the ADDIEM is either. They make so many, I'm sure that some custom combo would be no issue for knowles. It measures like the good bass one but it sure doesn't sound like it. The bass is vague like it's underdamped. Not boomy underdamped but like it's lost reinforcement like when a cabinet is too large for an acoustic suspension driver. They're vented and I feel they overdid it. shrinking the vent a bit gives them more boogie. http://en.goldenears.net/en/files/attach/images/108/130/002/8ef8eac983e56b65e587139acd9e4647.png

Well I can tell you guys that the bass in the JVC FXD80 micro dynamic drivers are outstanding in clarity, depth and weight in the bass. I'm amazed the sound coming out of this 5mm driver (and the black space around instruments).

Doesn't surprise me and I know you like extended bass. Hows the top? Some of the micros have been a little crisp.

Yeah, agree, how did they do that?

Excursion. You trade something so they're likely a bit less effecient than they could be.

Top is great. It's pushing at being a little harsh, but not quite getting there. Sometimes it's hard to believe this is not a BA. JVC has taken this carbon nanotubes' technology to a whole other level. I'm quite impressed. Dynamic sound with a wonderful timbre and near-BA speed.

Sounds like a light rigid diaphram bonded to a compliant surround. It's what I would strive for. It can likely be sealed and still make bass because the diaphragm is a smaller % of the total volume.

The only problems it might run into are in linearity department due to the compliant surround.

Might also affect lifetime negatively, but I would still expect it to last far longer than necessary.
