2 subs connected to a 2 channel amp?

I think James was stating that you’d likely want to have left channel information sent to the sub closest to the left speaker and right channel information sent to the right sub. 

Will you be running a preamp? Streamer direct to amp? Or both? What subs? Depending on answers maybe just a y-connector would be easiest, but it doesn’t sound like you have RCA inputs on the subs.

People can correct me if I’m wrong here, but couldn’t you do a y-connector out from the Node’s subwoofer output with one signal going out to each sub’s LFE in? I know you can select the type of options for the Rythmik sub, and if I remember, the HSU had an LFE input (Left Input would be used only per HSU). You would then use the Node for its variable volume control.
 

I used to own the ULS-15 and currently own the Rythmik F12G. Both companies are fabulous. I appreciate the Ryhmik’s flexibility in terms of its dampening options (kind of like HSU’s Q-Control), parametric EQ, and variable crossover (HSU 0/180 phase only).

John - correct on the above if I’m reading it correctly.

Node > sub out > y-connector (male to two female) > separate RCA runs to each subs’ LFE. 

Node > RCA R & L output > Amp R & L input

Master volume through Node’s variable volume control. If the sub’s signal is low (like you’re needing to really push the gain on the subs) you could also play around with another y-connector (female to two males) into R & L inputs of the subs.
