I asked about these a few weeks back before i bought my CDTs, a member said he ordered a set to have them come in and one woofers lead wasnt connected, and there wasnt enough lead to solder himself so he sent it back.
Only for the next set to have a woofer with BOTH leads left unconnected and they were too short to connect himself. That was just his bad experience i guess but its worth mentioning, i thought they looked good
