FS: Massive Audio CK6, Nano N3, and QC15 subwoofer
All of this is brand new, except for the CK6 comps. They were hooked up to verify functionality, then put back in their boxes. QC15 and Nano N3 amp have not been hooked up. QC15 has been checked with a multimeter though to verify it is brand new and both coils are great.
