I have an oulaw audio lfm-1 sub that i love, its basically a hsu research sub. I just aquired a paradigm pdr 8 and some paradigm speakers i am going to use for my surround backs. my question is if it was your setup would you hookup the 2nd paradigm sub in addition to the lfm and run two mismatched subs of different sizes, or isnthere not much benefit to hooking it up, and it will just throw off the system (paradigm studio 5.1, then 2 paradigm atoms for surround back) thanks!
