Just purchased a f113 and have been listening over the last 24 hrs so still adjusting but at this point I can say it is very, very, very quick, accurate, muscular only when called for plus it has a sense of effortlessness in power (so that's what 2500 watts of power does!). I'm not into home theater but I had the pleasure of visiting Dr Bill Gaw last week who has 2 of these subs in his room and when we watch the gladiator scene of GLADIATOR my palms actually were sweating! It was a wow experience. The JL Audio f113 has put my 2 REL Stentors to bed, may they rest in peace (and for the love of me why couldn't REL have placed all controls on the front of the box!).
