Philip,
This is exactly what my post on DIY Y-connectors is about. I have Paradigm P70's which also have built-in subs. The Y-connector will allow you to split the single LFE out on the 950 into two equal inputs for your subs. There are several pre-made y-connectors avaialble, including one made by Outlaw, but I'm looking at making my own and am currently seeking help (via this forum) on the best design for this.
