[QUOTE="bbe22, post: 1095989, member: 863"] A PR is tuned by adding weight . easiest is to have a bolt and nut and add washers as needed. saves one sticking weights all over the backside of the cone or in the (no longer used) voice coil area of the converted driver. So ...........trim the voice coil short, epoxy a short (? 25mm) say 8mm, or so, bolt, right in the middle of that stub facing to the rear. You then have a nice carrier fitting to add weight / washers . [/QUOTE]
