A couple of months ago I added two ELAC-2090 subs with very good results. JL Audio would have been the other option. The advantage of ELAC is that it has DSP inside which is practically a must if you want to integrate properly and deal with room issues (nodes and modes), too. Also, it seems that every expert says that for even results you need at least two subs (four is optimal, and not only for HT).
I tried crossing at 40Hz, 65Hz, 80Hz and settled at 80Hz (both high-pass and low-pass filters). I had really bad modes in the room at around 62 Hz, so I can take care of that through DSP in the sub. To set the whole thing (phase, parametric EQ, etc) I really needed to take measurements. I ended up buying XTZ Room Analyzer Pro II which is perfect for this. Sometimes we spend huge amounts on cables and accessories and don't even know if we have any serious issues with the room.
I found a lot of useful stuff here: http://www.acousticfrontiers.com/categor...libration/
I am still finalising the sub set-up but quite happy already.
