I am in the process of purchasing a HT for a 12x12 family room. I am looking for a sub that is compact but will still deliver good performance and gets low enough for movies. After some research, here is my list of proposed subs: Velodyne Minivee Sunfire Super Junior Def Tech Supercube II or III Paradigm Ultracube 10 Paradigm PDR 10 These are available to test out at local stores and all seem to fit the bill on paper. I have NHT L5 speakers for the L/C/R No receiver yet, but probably the Onkyo TX-SR606 or the new Denon AVR-1909 Any experience with these or opinions as to which is the best?
