Just a note. Put the shorter pair on the woofers. If there is a timing issue at all at least the woofers will start first. Typically the speed goes to the high end. Personally I would just run the cables you have to the tweeters and jump down with about 8” of rocket 88. You can even experiment with other jumpers from other companies. Try not to use the factory gold plated metal jumpers. If you do use them connect your speaker cables to the high side. Maybe borrow a pair or buy a returnable pair of Rocket 88s so you can see if you hear a difference and you like that difference. I feel there is better way to spend your money like IsoAcoustics for your speakers or your gear. Especially your digital side. You should prioritize your money to where it makes the most audible impact. I will bet you will make a bigger difference with a better power cord than a second speaker cable. It all starts at the wall. Try before you buy so you’re not going down the dreaded rabbit hole. This hobby gets expensive.
