Unless that high pass filter is male-male (and they aren't) I need two males and one female on the splitter cable. Males for the preamp out and amp in and female for the other RCA cable I'll be using to hook up to the sub.
Look I am just trying to help. I don't know what type of cabling you're thinking about but the way I figure is you need as I stated above.
From the preamp out you run the splitters (two of them) to the left and right with the male ends (like I linked to) from the
female ends ,two of them for each splitter, you run the interconnect cable left and right back to the main in on the amp section of the Nad. You can insert the hight pass filters directly to the main in.The other
female ends you run left and right sub cables to the amp of the sub.

Unless you are thinking the sub needs a single RCA input. It does not, the X-sub has stereo low-level inputs which should be fine for this.
You need not tell me what the X-Sub needs, I own one.
