Default 18" burn in

Hallo to eneryone, i have a question about the change in T/S param. after burning in. My EV DL18MT has Fs 25Hz (burned in, according to datasheet). The 2 pieces that i bought had 39 resp. 40Hz. After 2 days with a 4w 6Hz sine tone (was afraid to increase power, cone moved already a lot) they are still around the same values (a couple of Hz lower).
Was the burn in not enough (speker has a hard suspension, not a rubber one), is this kind of deviation betwwen new-used usual? Is there a better method to burn in the speaker?

T/S deviation was smaller (25% more Qts as in the datasheet).
I would greatly apreciate any opinions, i'm very puzzled with the situation.
Thanks in advance
Greetings
Konstantinos
