You bet you can, I recently had a recommendation from Robert Stein of The Cable Company (a good guy) at ([email protected]) to upgrade the nuetrik speakon connector for REL subs by having XLO custom make a Pro-600 nuetrik to a 3 wire cable, terminated with banana plugs. I then used Monster X-Terminators to piggyback the new cable to my already crowded bi-wired speaker terminal. Robert felt that the cable upgrade was about as good as an upgrade to the next higher REL sub category. I got an improvement in pitch and instruments became more full sized with the new cable as well as a feeling that the sub was "exciting the room" and not just adding the lower frequencies to my B&W 805's. It should cost under $250 depending on the length you need. Let me know if you pursue this, and how it all works out. According to REL, this shouldn't make a difference, but they agree it does! Good luck.
