Are u getting the new Tin P1 Max? I think the P1 Plus will be overhyped by the Max now that a new release is out. But very strange decision to push the Max out just a few weeks after the P1 Plus was launched.
Anyway Tin HIFI recent products have been quite hit or miss. Tin T3 Plus is decent enough (though I think it is overrated -> Olina, Dunu Titan S and Aria are better single DDs at the same price). Tin T2 Evo, P2, T5 were flops. In fact, the latter 2 necessitate retuned releases a few weeks after release.
Actually, some of these Knowles BA with a 3 kHz spike are tuned with a knowles damper/filter in the nozzle. The spike in the graph is only present when undamped. So in practice, this 3 - 4 kHz area can be lessened.
Putting in and removing the knowles filter as such:
These Knowles dampers can be bought on aliexpress or amazon, just search "knowles filter" or "knowles damper". Do buy a damper removal tool too for easier removal of the filter.
I bought mine here: https://www.aliexpress.com/item/32580267018.html to play around, they really do work, but you can just buy it from the cheapest shop or something. There's various damping ratios, and other then damping the treble, they can also influence soundstage to some extent.
That's a nice information. I don't know if they bothered and put a damper in DT6Max like you mentioned. I think the diameter of the nozzle of Shure series is smaller than what SF uses. If there's any with bigger diameter, I'd give it try with my DT9. I need to use EQ to tame the sibilance and harshness of treble part on DT9.
