I would say none of single type driver make perfect sound, just different pro/con ...

    The Outer dia. is the same but "atmospheric" one has a narrower inner d and the overall length is also longer while the reference and transparency pairs they have equal inner d and the transpareny pair having a shorter length. No damping material whatsoever.

You may want to  check this out, these have different inner d and damping material according to the target response and they work unlike the Kirin's.

Just checked out the FH7's tuning mechanism which I believe it only employs physical dampening of the BA in the nozzle.

    By adding extra drivers you will also be introducing new sources of distortion and nonlinearity. As revealed not too long ago (well, by myself), you can never put a real passive crossover in an IEM so you can only inherit the distrotion of the bass or full frequency driver (which is often a DD). You actually likely risk getting a higher incoherency by adding more drivers not to mention the 90 degree rotation in phase of the signal. This is exactly why you often hear people calling a multi driver set "incoherent" but you don't hear the same for single DD sets.

Just for pure common sense discussion as I know nothing about those technical issues...for multi-driver unit, if there are overlapping of frequency ranges among units, then they should cover each other without sudden "disappear" in certain range...provided that no issue of incorrect phase...

I agree that single full range DD should perform more linear just around the mid, but problem might occur with rapid high energy demand from both extreme ends of the high and low...correct me if I'm long

    I think the reasons to add drivers on top of a full frequency driver is to add note weight and resolution to the overall sound. and this addition is often very subtle. The SPL doesn't really lie, if the driver responses to the signal it is reflected on the graph so it is non realistic to imagine a sudden "disappearing" of certain frequencies in the full spectrum. I think you can actually measure the frequency resolution but I have never seen anyone doing that.

I have never read any articles about simutaneous extreme frequency response but I think that is actually quite rare. A burst or a continuous signal they are the same and I bet the drivers still respond the same way and there are many more factors that affect the quality of the sound such as intermodulation distortion (such as due to what you called "overlapping") created by more than one driver. Also these tests are done with a white noise signal so maybe the THD measured is faithful enough.

再對比左MAX 同Kirin, Kirin 係真係高清幾多, 應該因為佢10kHZ 後遲左rolloff, 打擊強D 快D, 但就係比DD少左一點包圍感, 成個感覺都係好快同比較黑. 但係真係比MAX 更3D 多可能20-30%.

聽師兄咁形容都似係平板同動圈既分別, 對Kirin 真係做到野, 低頻好快咁冚入耳係過癮
仲記得個時試Audeze 對新入耳平板Euclid, 完全覺得好似聽緊動圈咁, 唔知做咩

Euclid有機會係唔夠力推18mm單元.

師兄出動到sales 口頭禪喎

我相信劈價說明一切
Timeless 都好聽過佢, 大家高頻都唔算好靚, 起碼個低頻有feel 啲先
