Hi everyone,

I just got a pair of 130A 15" woofers for a DIY Hartsfield project. The cones are the correct 130A cones with the paper dust cap and are marked as such in white pencil on the cones.
I noticed that one speaker has a much softer suspension than the other and the cone move much more easily when very lightly pushed with my hand. Also when I tap on the cones, the fundamental of the loser cone is much lower than that with the stiffer cone.
loosen

My question is should the firmer cone loosen up with use like the other?
Im thinking that the loser one was used more than the stiffer one. Does this make sense or does "break in" not make the cone much looser?

I obviously want the drivers the be well matched for both speakers.
The cones look to me like older re-cones that were not used much since the look nearly brand new and the speaker dope on the surround also look like a re-cone job and not stock JBL.

Thanks,
Matt
