Hi Martinmobile...
Thanks for the nice words. I have the 101 sit on a black slab without spikes. I don't want to elevate the 101 any higher. Sitting on the slabs, the bass hit tighter & more taunter. As for the sub, i only use it for the movies and one f112 is plenty. I use just one jl f112 and it is a killer for movies in my 16x19 room. The f113 is good for larger size room and the f112 is better for small to medium room. It blend in with my 121 center perfectly. Either watching movies or listening to musics, I'm in MBL HEAVEN!
