For an 3-Way System? Wow... that is more than i expected, much more.
I am looking forward to hear how these compare to offerings in the same price range.
The FA9 was very easy to recommend with good foam (got forbid the ones shipped with the IEM) which sold at 550€ MSR and 350€ on sale. It had an excellent tuning and only minor issues which was very very rare for the price it sold for.
For that price, i expect the FA19 to compete with the SE846, IER-M9, Mach 70 and similar offerings.
Especially i am curious if the vent affects isolation
From my field tests, the FA19 has slightly above average isolation, but is not as isolating as those non-vented pure BA types.
But the vents are a double-edged sword, the vented sub-woofer makes the BA bass in the FA19 sound very close to a DD bass in terms of movement of air and decay.
