Of late there seems to be an explosion of AMT's even in parts-express -
Has anyone tried - Free shipping AMT Ribbon tweeter car speaker-in Speakers from Electronics on Aliexpress.com
At barely 20 a pop shipped - has anyone tried them ?
How about the planar magnetics -
Ribbon tweeter 8 magnetic stripe-inOther Consumer Electronics from Consumer Electronics on Aliexpress.com
Seriously the sawafuji's I thought were very very good in what they delivered. They made excellent emit replacements.
Thanks.
Srinath.

I am not sure about that - "you get what you pay for" mantra being appropriate for everything about china.
Chinese have been close behind the japanese in electronics going back a few years. These things take hours and hours of labor from skilled people with small hands. I think its near impossible to match the chinese in that regard.
Metal castings and other machined components - forget it, I'll never buy chinese junk - though I think some of it has snuck onto my wife's accord. My stuff is all not even from this century, so I have very few chinese metal parts if any.
Cool.

I was more or less chiming in about materials as well. The Chinese mfr their materials themselves and almost always have copied non-Oriental products. In what i think is true about materials mfd in China - the finer the material mfg the higher the prices can be. Lots of expensive material manufacturing comes out of China now and... there's plenty of low-end materials being produced there.
To wit; not only steel and / or cast portions but the Kapton substrate and circuit metallurgy would be my issue with a wholly inexpensive amt vs. the labor to fold the diaphragm and adhere the conductor, as an example.

We have rules about politics and this is toeing the line. Please discuss these things via PM.
Thank you.
In Australia, to "toe the line" means to conform to the rules. I think you meant to say the conversation was getting "close to the line".

Have had a few chinese amts and for the most part are rather difficult to make a poor design unless you're completely inept. Upon those I find little to dislike. One thing that threw me prior to purchasing the rt4001's was a disagreement in the sensitivity spec. Manufacture claims 89dB when others and including myself rate them for 93-94dB. Being purely resistive in nature it's an easy fix passively (resistor) and a pure positive if done active (dynamic headroom).
Airborne RT5002
I've mocked up an as-yet unfinished-cabinet using the RT5002 and a HiVi F6 (Nephila). This AMT advertises as 2.5k+ range and 95dB, but it comes out closer to 100dB, and 3k at the lowest in terms of inherent response. It also needed a notch in the response to flatten it out- but you have 100dB to work with so it's really very okay to do so.
All that said- these sound VERY(!!!) good! I'm also daring to use the term 'holographic', because that is what at least 2 other people used to describe it.
