Well went and bought the Velodyne VX10 for a good price. First sub so will have some questions getting it set up. I have the cables for it. Have an Onkyo SR605 so just going to plug into sub woofer jack on back of onkyo. I am unfamiliar with this cross over stuff. Only have 2 front speakers now. Once I connect sub and change in the menu system of receiver that have sub what crossover settings do I set on sub or in receiver.
