Default AudioLabs DQ30TZF-04, nope.

In my search of little performing locally available, I stumbled into this driver, and was surprised there was a thread in here about it.

Mirage's Latest Crazy Idea - Baffle-Less 2-Way No Xo

I thought that looked promising, nice FR, low MMS, highish QTS... so I went ahead and got me a pair.

First impression, the body is nice, but the frame is that flimsy thin metal found in 80$ of the drivers available here. The surround looks like a piece of thin suede.

I placed them in my TABAQ and played a few songs with them.
Yikes. Not great. Not great at all. Music is undefined, no punch, in a word... sloppy. Anything that has a little bass in it makes it distort like crazy, totally uncontrolled. I had to put a HiPass filter at 196Hz, anything going under would make the cone start to fart! Also, highs are missing.

So I went ahead with some measurements in REW.

And it looks like the highs drop drastically starting at around 8kHz.

So, this was a miss, and certainly not the same experience as the link provided to the other threat above.

These will go in the toys' bin. They were not worth the $30 a pair plus shipping I paid.

That is some serious distortion, what level were you playing them at?

I thought the surround looked like chamois suede leather, and it is! ?

Level? About 75dB at the mic's position. Not overly loud when playing the sweep.

Could have a conversation next to it if talking a little loud.
