JL Audio Fathom f113 Sub – Review by Choice Audio

It is hard to describe our feelings when we heard our first f113 Fanthom Sub installed and set up in a listening room. It is truly a wonderful sub with top performance and gorgeous looks.

For movies the f113 can deliver room-shaking results with zero distortion. Often people think a sub should rumble and make a boomy noise, but in fact this is distortion. The f113 disappears into the room and you cannot pinpoint the location of the bass. Bass response on this sub is fast, deep and accurate. There are few subs on the market that can deliver results like the f113. Only three or four come to mind, and they are not inexpensive.

The f113 performs admirably with both music and movies. There is some patience required in getting the f113 properly set up, but it is much simpler with a receiver or processor from Anthem. The ARC systems blends subs better than any room correction that we have heard. If your preamp has bass management, then you are in luck. If you are using a standard, 2-channel preamp with no bass management, the best way to dial in a f113 is to use an outboard crossover.
