JL Audio

I agree with pgeek.

I have the F110 and would recommend 1-F113

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.

Sailcappy makes a good point about how a cable can take a sub from good to great. When I added the Synergistic Subwoofer 2 XLR cable to my system, it was as if my JL-F112 took singing lessons.

Tried the f110(not enough) and the f112 (enough). Friend had a Velodyne Optimum 12 and brought it over. A/B'd the two and the Velodyne actually sounded tighter and more powerfull. Have since returned f112 and purchased Optimum 12. Saved almost $2,000. I strongly suggest you find a shop that will let you demo numerous subwoofers before purchase. All rooms have different acoustics. JL is very good but in my belief it is overpriced.
