Better Subwoofer for 2 channel Music: Focal Utopia Sub or JL Fathom f113


Hello Everyone,

I am looking for a good sub at about the 2K price point and am considering either the Focal Utopia Sub (15" woofer, 1000W RMS) or the JL Fathom f113 V1 (13.5" woofer 2500 RMS)- The fathom being slightly more expensive on the ’used’ market.  Both subs are highly rated and the Fathom seams to be very highly regarded on this site so I would like to try it. At the same time, my speakers are FOCAL Utopia BE series so I think the Utopia Sub will gel nicely and I would be able to save several hundred bucks to put towards other tweaks if I went with the focal sub. Currently I have a Monitor Audio Gold 12 Sub (12" woofer 600W RMS) which is very good, but want to see if either the Utopia or the Fathom is much better,  and I mostly use the Monitor Audio in my HT set up anyway.

Specs wise:

Focal Utopia BE Sub  - 15" woofer, 1000W RMS

JL Fathom f113 V1  - 13.5" woofer 2500W RMS

Both subs go down to ridiculously low Hz.

Usually, I am less into specs and more about hearing music (and not sure how important these specs are anyway) but I am not able to audition either of the subs (let alone in my system) , so kinda shooting in the dark and would appreciate some advise on which way to go as these are also heavy and expensive to move around to deal with!.

I imagine I will keep the new sub for a while.

I’d like the sub to merge with my speakers as seamless as possible, and provide that extra lower-level feeling and punch when needed.

Does anyone have experience with either (or both to compare)? Thank you in advance.


Aside -   My 1 pair of preamp LXR-outs is taken up by the connection to the Amp. So I would connect the sub via one of the two remaining RCA outs from my preamp - is there is a better way?

Hi jamarshak,

I've had subs for years and can share my experiences and 'growth' as it may be;  For many years I have had several M&K subs,  They were the sh## in their day, dual 12" push pull, very articulate but not the absolute 'deepest'.  But what I quickly learned, was that two stereo subs, each being fed by distinct left and right inputs if possible, was way better than one sub, no matter how great it is.  +1 to noble100 on that.  (and I am sure that 4 in an array is the best but that is not going to happen for me).  Anyone that says you can not localize where a sub is is just wrong or can't hear.  I can sit right in the center with one sub blindfolded with mittens and tell you where the sub is, even when adjusted well.  So two is the bomb.  About two years ago I got a paradigm studio 15 new on a  great clearance.  Wow.  Deep and low.  but just one...(the M&K's are now gone).  So I got another and had stereo 15' paradigm's, pretty nice.  
But the lady thought they were hideous, and I was able to use them downstairs, so I started researching Rel.  Now I feel I have grown up about bass and subwoofers.  I now have stereo REL Carbon Limited's.
It is not about just hearing and feeling the deep stuff, but it about how they pressurize the room and support the stereo imaging and sound of my Revel Studio 2's.   I have a large room, all open from family through eat in area to kitchen.  So  a lot of air.  The sub's you ask about are also awesome, but it is about how the REL's feed their input off of the amplifier to receive the 'exact same timing etc' to keep everything sweet.
I also use the Longbow wireless and it works easily and perfectly.
And get this, the lady thinks these REL subs look good!  Read everything on the REL site before you purchase anything.  The Rel SHO 5's would have worked but what the hell...and you can find discounts on new REL subs.
