List your extra audio gear here that you have and are not using, or anything you might want to sell sometime in the future.
Inspired by Zeus121996 who had an unobtainium CF-3 woofer that now looks like it will be going to a new home. List single speakers, spare sets of speakers, woofs, crossovers, horns, amps, or whatever you have in the basement collecting dust. It does not mean you want to sell it, but if someone is looking for something they might contact you to see if it is available.
You can list a price, but that is not necessary.
I put this Inventory thread in Tech Mods, but let me know if it should be moved to the For Sale section.
