I had both the F112 and the HSU VTF-3 HO. I don't have either one now, but to me the JL sounded much better. The HO may have had a bit more output around 20hz but the JL was better from 40hz and above. The JL was also much more articulate. Could hear much more detail in the bass for movies and music. For about the same price, you may want to consider a pair of Rythmik subs. The sound quality is superb and two subs should get you close to the same output of the JL.
