Yesterday I received my Chinese LCR meter. The reading on what I have are:
Jantzen CrossCap 30uF - measured 29.96uf/ ESR 0.3
Jantzen CrossCap 30uF - measured 30.30uf/ ESR 0.3
Jantzen Superior-Z 5.6uF - measured 5.56uf/ ESR 0.0 ?!?!
Jantzen Superior-Z 5.6uF - measured 5.61uf/ ESR 0.0 ?!?!
Jantzen coil 0.85mH/0.45 RDC - measured 0.88mH/0.56 RDC (similar for the 2 that I have)
Interestingly Jantzen Superior-Z measured ESR is 0.00. Can this be true or the value is so small that the meter isn't picking it up? But than again .....too small I think? The specs for the meter is(if we say we believe AliExpress):
Capacitance: 25pF- 100mF
Resistance: 0.01-50MΩ
Inductance: 0.01mH-20H
I'll measure the parts that I'll remove from the original crossovers too.

The surprising thing is that you get an ESR of 0.3 from the CrossCaps. These are metallized polypropylene film and should have an ESR of very very close to zero. In other words what you measure with the Superior-Z.
I suspect that your meter is not telling the truth with the 30uF CrossCaps. Either that or the 30uF parts are faulty.

New report.
Maybe I got confused. Just now I did the measurements again and CrossCAP got an ESR of 0.00. I tested some old electrolytic 6.8uF capacitor that was off just to compare and got 7.78uf/ ESR of 0.31. Maybe the numbers got mixed in my head. So CrossCAP ESR is on point!
I will edit my previous measurements if I can.

Pockobg: The team at Jantzen are super helpful. I asked for a 13AWG 0.12mH inductor with bigger inner diameter then the one they have in there store.
They made me 4 inductors with 25mm ID, the one they hade in store was 10mm ID. No extra cost, just payed for the inductors. Now they have it in there assortment. Frank
