I bought these for an apartment in the city that I no longer have. Instead of these sitting in my closet at home, I'd prefer if another enthusiast used them.
SX-1115-RT - $100
SX-1120-RT - $100, each
Flatpak SA-82 - $100
These prices are very reasonable; shipping is extra - you pay the actual rate.
Let me know if you have any questions.
