REL subwoofer crossover question


Hope someone can help me out with this.....I am somewhat familiar with how the crossover settings work on REL subs (2 Brittania B2) but don't know if they differ from other manufacturers such as Velodyne. My question is should I be hearing bass frequencies in the 60-80 hz range when I have the crossover setting at the A 1 position (which according to the manual rolls of at 22 HZ? I'm not too familiar with how the crossover rolls off, but I'm surprised that I can't get any rolloff below 80HZ. Is this room nodes/issues or what? I have played a little with placement and all but haven't gone crazy with them. I am using a single RCA for the left one out of my preamp and vice versa. (I haven't tried the neutrik connections yet, have to purchase if the are truly better). Any thoughts? Thanks.

Neutrik Speakon plugs are ridiculously easy to install on a proper cable (any decent 4 wire speaker cable should work fine using 3 of the wires of course), and I've found that method seems to work best with my groovy old REL.
This may sound simplistic (and might actually be wrong) but somebody at a "boutique" hifi place told me that when hooking up the REL to a Class D amp you connect the 3rd wire to ground on the amp chassis (the other 2 to left and right positive speaker plugs).
