Try them all and decide. There is no one single "best" for all purposes, that's why you are provided options. There is only best for what you are listening to and for. Your room, your music and your priorities will establish the "best" connection. Depending on your situation I would begin running the mains fulll range.
My receiver does have bass management but I am trying to utilize the speaker cables that are already in the floor and walls. I pulled high grade speaker cable for bi-wiring the sub and speakers when we did a complete remodel a few years ago. I can't pull an RCA type cable for the sub now so I'm kind of stuck with speaker level wiring.
Cookie, I don't know how your reciever utilizes bass management but I would connect via either line level or connect the sub directly to the LFE channel. Either way you want the option of controlling the volume and crossover point with the receiver or processor. You'll have to set the montitors to "small" and hopefully you have options within the receiver to control the x-over point. Personally, I wouldn't use speaker level inputs/outputs on any sub, degrades the sound too much, IMO.
