Description: Condition is Used and Tested, working 100%. I love these speakers and recently installed these in the rear deck of a Mercedes, but with the new addition of a Focal subwoofer, the bass was just overpowering and I felt these mid-bass speakers were being underutilized/wasted so I removed them from the system and opted for some mid-high range units instead. These are 8ohm speakers so to wire them up to a 4ohm/channel car amplifier you will just need to wire them in parallel. I had to repair a cracked Zamak alloy basket arm on one of them but the cone and magnet were not functionally affected. I researched Zamak alloy repairs and thus the repair was done properly and turned out 100% rigid and does not affect the performance or functionality of that speaker whatsoever. It is not even visible when installed in a box anyway but just wanted to have full disclosure (picture included). I have two pairs of the speakers, so four total included in the auction. Nothing else (such as the custom rear deck or smaller coaxial speakers) pictured is included except the four focal speakers.
