Tascam TH02 Measurement
« on: November 03, 2013, 05:08:20 PM »
I got the stylish white colored edition. The measured slight bass drop is less than it is with real life. Being a larger supra aural, it wasn't possible for me to get a perfect seal. It measures well, but there are some funky internal reflections stuff going on. Dynamat, acoustic stuffing, Creatology, etc. should yield gains.
  • The 4k distortion spike (and probably 8k ringing) is noticeable and not pleasant (but not horrible).
  • Lots of bass slam. More than is indicated in the measurements.
  • They are light and comfy - once I bent the headband so there's less clamping pressure.

Thanks for measuring these.

It killed my curiosity a bit as the 5% 2nd harmonic distortion at 4kHz is a bit much, this seems to be a driver problem (or enclosure ?)  :-[

Maybe I am wrong and modding brings out the best in them.
The peak around 7kHz seems to be reducible (quite easily I might add) but wonder if that were done mechanically (felt of sorts) if that would reduce the adjacent band as well.
The whole 'treble' area seems to be verging on 'trouble' judging from the CSD.
Maybe it isn't as bad in reality though.

As shipping these things from the USA costs more than the whole headphone itself I will skip this one (unless it becomes available in Europe) but am told they are not going to sell these in Europe.

Thank you very much ! I was expecting little better results... and Solderdude is right D2 distortion is driver problem, nothing gona cure this, but they are still good cans for the price

Would you mind to try removing cups and measure this way?

Thanks Marv. Looks like a nice modding candidate. Once I get them I will be putting them into some wood shells and experiment with damping and better pads.

I will try to do an open driver measurement.

As far the the distortion, I am not gonna bitch at $24 shipped.

Yeah, one just has to look at the D2 spike of the HE-400 (http://www.changstar.com/index.php/topic,1127.msg29907.html#msg29907) at 4kHz and consider the price of these cheapies ... The FR looks nice enough.

Thanks a lot, purrin. I too wonder if the ringing is somehow fixable, has anyone played with adding mass or doping to large mylar drivers?
These are more than worth the asking price just for their bass performance, I think.

In the scheme of things, it's not horrible. LCD-X ($1699) has a very similar 8kHz spike. Felt in front of the driver would be a good idea, although 7kHz is on the low boundary of felt's treble reducing effects.

That looks pretty damn good for the price. Should be a good candidate for modding. I have some random pads I can try on it. Curious to see if the HM5 pad works, as I've had good luck with that on other headphones. I'm going to order a pair.
