It could be partially speculation . but not completely, as the bass drivers need some time to relax (spider movements and cone stiffness) from the factory production period if it is brand new. For tweeter and midrange it could be speculation as I'm not sure if they need time(may be some one can provide their experience).Thank you for your subjective opinion! I think it that “Now that i feel the new R3 metas ran more than 100 hours, i believe it might have opened up.” is pure speculation and a figment of your imagination
