Guitar amp speakers.

Are these refurbished? http://www.soundspeakerrepair.com/speaker-parts-cp/JBL-D120-F-Recone-Kit/KIT/Recone+Kits/

See http://www.mylespaul.com/forums/tonefreaks/173257-speaker-shootout-video-celestion-greenback-vintage-30-jbl-d120f-etc.html

I think speaker quality has improved in leaps and bounds since the 60's.
