arficus Posted June 14, 2022 Share Posted June 14, 2022 Just did my first recones - couple of Jensen P15LL. The surround/suspension on these all paper aftermarket cones seem substantially stiffer than OEM. I know they will break in (and I have been pumping them with ~50hz for a while), but even with this I think they will be overly stiff. Anyone have any suggestion for loosening them up? Like a chemical that very mildly degrades cellulose? 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted June 17, 2022 Share Posted June 17, 2022 Keep pumping the dub step! My new H4 woofers took at *least* 72 hours at tolerable volumes to loosen up so they sounded like the ones I heard in Hope. Have you considered that the old cones were too loose? 1 Quote Link to comment Share on other sites More sharing options...
