bi-amp setup with 2 RM 1000Ws

After owning Polks for over 25 years, I'm thinking about changing my setup and need some advice. I'm currently running a mid 80s vintage setup consisting of first gen Monitor 5jrs (no passive radiator), and an L.F.14 Bass Module (subwoofer) driven by an NAD 3155 integrated amp, NAD 2155 power amp, and a DBX 120X DS electronic crossover/subharmonic synthesizer (owned since new!).
Currently, I have the system setup as bi-amp with the 3155 driving the 5jrs (satellites) and the 2155 driving the L.F.14. Even without the DBX, this setup allows one amp to be dedicated to the satellites while the other is dedicated to the subwoofer. With the DBX, the electronic crossover further dedicates the signals supplied to each amp according to the selected high pass/low pass frequency (50 - 210 Hz). Pretty simple!
After installing new cabinetry to accomodate a larger plasma monitor forced the subwoofer to be moved further to the right of the room there was a noticeable decrease in bass presence as well as a right leaning imbalance in bass response. To remedy this, I decided an additional L.F.14 would do the trick, but discovered these units are rare and hard to find on the used audio market. So, I did some poking around and discovered a suitable substitute passive subwoofer from Polk - the RM 1000W - and immediately found two available online, which I intend to purchase, but need a bit more info before pulling the trigger.
All of the references I have found deal only with setting the RM 1000W up for single channel (via the blue terminal post mthod) for the purpose of using two of these as L/R channel subwoofers wired to the amp(s) with the L/R satellites wired to the corresponding subwoofer. What I intend to do is drive the L/R satellites with the 3155 and the L/R subwoofers with the 2155, bi-amped and through the DBX as I am doing currently. So without any docs or wiring diagrams to reference I'm hoping someone can tell me whether I can do this, and if so, how I would wire the RM 1000Ws in this configuration.
Any advice and council will be appreciated!
