Hi all.
When building my new subīs, i got over this funny thing, and maybe some of you can explain.
I got 3 2243H, and as you can see, they meassure different imp.
First i meassured with "cold" units, and then apllyed 10Hz for 20 min and the FS decreasses a bit for all 3 units. By the way, it was in free air.
So my gues way that the units was damaged or in some kind had been exposed to heavy amplification -- but look whats happening when mounted in 170L cabinets (not yet tuned finally). They meassure excactly the same SPL from one meter in center of the cone.
The picture with only 3 imp. curves is the units mounted in cabinet
Sorry the Danish text at the picture.
Why is that ?
And dont mind the db numbers also in the left side. they are not true. (But the ohm values are !)
