Introduction

The JL Audio has produced a very serious subwoofer in the Fathom f112, the smallest sibling in their home audio line.. This is a powerful sub capable of prodigious deep bass output. Make no mistake; if you have loose objects in the house, this sub will locate them and point them out. Also, be prepared to find interior partition walls complaining into adjacent rooms. For the best possible listening experience, find all loose items and secure them. For those who have not experienced a subwoofer capable of generating bass to the limits of human hearing, one with substantial output capabilities down into the subsonic range, the JL Fathom f112 with acquaint you nicely. Add this sub to your auditioning shopping list if you are after ultra high performance, reasonable box size and cost.

driving home on Friday a commercial from a local Toronto retailer made mention of the the new JL's having arrived. They went as far, as to call them the subwoofer of the Gods. Auditions will be for serious audiophiles only and by appointment only.
Then, again I'm not surprised because I would line up to have a listen .
Ps: I am serious, just don't have that kind of money.

The local Toronto retailer would be Kromer and I just auditioned the f113 yesterday for a possible purchase at the end of the month. To me the f113 is not a WOW sub (spl) it is more of a “I didn't know those sounds/effects were there!” It is one of those rear audio components that reveals “stuff” that you could not feel before, because with this sub you do not need tactile transducers.

Go listen/feel for yourselves.

David's review and forum response has inspired me to request a review sample of their Gotham sub. Problem is I loath carrying a 300lbs sub up two flights of steps to my theater room, and knowing me, I'd want at least two of them

That's what JL's own top end demo room uses. Bryston electronics, PMC speakers, and two Gothams on the front soundstage.

I fully concur with post 14 & 18. Well said, no.5

Oh, stop… you'll make me all embarrased.

Thanks though.
