There is now a chance that I may need to change out the diaphragm in addition to the dampening pad on one of my 2441. Is there wisdom in changing out the diaphragm in the other 2441's even if it is working so both can match? Is the sound of the JBL-D16R2445 diaphgragm they sell similar sounding the original diaphragms in the 2441? I had read some posts stating that radian audio's aluminum/beryllium(?) diaphragms might sound closer to the original.Thank you in advance!
