I have one JL-F113 and an extremely satisfied with both music and movies. My Arcam FMJ-888 has a built in eq and speaker set up. After running this I no longer have the walls shaking but excellent balanced low end. I did do some tweaking to the sub. I had Bright Star Audio create a stand about 12" high that I filled with sand. That alone made the sub more musical IMHO. I then upgraded to a Synergistic Research Subwoofer 2 XLR Cable. OMG that cable mellowed out the boom and now I am extremely happy with my investment and choice. One is enough if you assist it just a little. My two cents.
