I have a pair of lightly used M-400t Carver Cubes (Serial # 024355 B and 22867 B) plus a Z-1 Wide Band Z-Coupler. I bought them right out of college with grand plans but never used more than one at a time driving a few rooms in my home. I am looking to sell all this as a package. Any recommendations as to the best route? Craig's list and Facebook Market Place just don't seem right for these. Thanks!
