Our HT Room is in our finished basement. The room is 22 X 13 with the only opening being the stairwell. I recently sold a Velodyne SPL-1000 and can say that without the LFE dedicated channel...I am totally missing out. The 2006's go low, no doubt, but the 8" subs will start to struggle with material under 40Hz...and even moreso under 30Hz. I love the 950 and wish I had the dough to go for the 755. (patience). My intention is to purchase a sub and then set the 2006's to SMALL crossing them with my 950 @ 40Hz. Will experiment with them set to LARGE too. Same goes for my CLR2300. BPX's are crossed @60Hz and this seems to be right on. The DEf Tech's will be very efficient with this material and the sub can deal with the rest. This means the sub I choose should really only be dealing with material under 60Hz that my Def tech's will not get and the LFE channel signal. I cannot wait to get set up with a sub again. Finally the 755 will be the icing on the cake.
