Why so many JL Audio Fathom subs for sale I wonder

I went for two F113's over one F212. My room is about 18x30 10' ceilings.

Hello Jp1208, thanks for the input. Question for you: did you hook them up as independent subs, each with their own signal input from the preamp/processor? Or did you link them together using the "master/slave" configuration.

And whatever you did, would you mind giving me more input about what you thought? or the percieved differences?

What did you think of the JL's you heard?

Greetings Mcpherson. I thought they were awesome. So much so that I'm thinking of selling my JM Lab / Focal Sub Utopia Berylliam, which is really a great sub and has been my reference for the last 5 or 6 years. I've owned numerous different subs over the last 15 years or so. Velodynes, Bag Ends, Von Schwikerts, Sunfires, HSU's, and the list goes on. Went through them like toilet paper for a while in search of the "perfect" bass (if that's even possible), then bought the JM Lab-Focal and loved it. Now I want to try a JL Audio sub. SO many of them up for sale here on A-gon. Just makes me question why, is all.
But I have indeed experienced them and they really do kick some ass. And of course....I'm kind of a "Bass Freak" "Bass-a-holic" and want to see/hear what a Fathom F212, or a couple of F113's will do in conjunction with my MBL 101e Mk2's, 9008A's, and my 6010D Preamp. I know. Why? It'll probably be too much, and completely unnecessary but I think it will be fun and the JL Audio stuff is quite affordable here on the Gon. It's the question of why the heck does everybody seem to be dumping them that gives me pause and makes me hesitate, that's all.
SO I thought I'de throw it out there and see what the fine folks on A-gon had to say about it. Thank you to all who have conrtibuted so far.

Well you know what? You've all convinced me that buying a JL Audio sub , maybe 2, is going to be ok. This is great to hear, and everybody who's contributed to this thread has made alot of sense, so thank you all for your input. I think I'll just snap me up a Fathom F113 and give it a spin in my listening room. Or would anyone suggest I buy an Fathom F212?? My listening room is approx. 15 feet wide x 18 feet deep with 9 foot ceilings. I'm running MBL 101e Mk2's with MBL 9008A's and a MBL 6010D. Already a pretty potent match, and when I run my JM Lab / Focal sub...the result is quite good. Actually it's DAMN good (not to sound like a braggart or anything). If I step up to a single Fathom F113 do any of you think that would be "sufficient" given my room dimensions? I wouldn't be looking to use the JM Lab /Focal sub in the mix any longer. Just a single (maybe a pair?) of F113's. Or just a single F212. Again, as mentioned in my original posting, I'm a bass freak. So it absolutely MUST play clean, tight, loud as hell, and hit like a sledgehammer. The JM Lab / Focal I have IS all that...but only to a point. I'm looking for "bone-crushing" bass. (Yeah, I'll admit it. I'm into ROCK, and Heavy Metal, hence MBL speakers, amps, and Preamp.) That having been said- and given my room dimensions- what would YOU folks do with regard to my quest for monster, ass-kicking bass?? 1? a pair? Like to see where others would go with this. Thanks in advance for humoring me about this.

Howdy Jp1208. So you ARE operating them in a Master-Slave configuration. That is interesting. Having not owned JL Audio before, I have often wondered what differences may exist if coupling one to the other as opposed to running them in stereo mode. Also, you (Jp1208) mentioned that you x-over at 80hz, and even 90hz. Personally, I have not liked the overall sound when setting any of my previous subs x-over points that high. I have generally set my x-over points at around 50hz to 60hz, and found that to be much more to my liking. I HAVE indeed run dual subs (of the same manufacturer) before. I've run 2 Velodyne FSR 18's, 2 Von Schweikert "Towers of Power", and 2 Sunfire True Subwoofers. All at different points in time. The big Velodynes were staggering and waaaaaaaaay too much for a two channels set-up. The Sunfires were friggin' terrible...I'm talking real hammered dog shit (only MY opinion), Muddy. Overblown. Distorted. Inaccurate. Shook the whole house but could never get them to integrate worth a darn. I dumped them quickly. The Von Schweikerts were probably the best overall pair of subs I ran in conjunction with a pair of Martin Logan Quest Z's. I'm still kicking myself for having gotten rid of them. Oh well, live and learn, huh? I always ran the pairs of subs in stereo, sending the left and right signals from my preamps, to each of the subs, respectively . Never used any sort of processor. Now here I am in 2013...15 different subwoofers later, and now it's time to try JL Audio. I suspect a pair of F113's might be a bit too much given my room dimensions?? But I'm leaning toward a single F212. Maybe? Haven't yet decided. My JM Lab / Focal Sub Utopia is really an awesome sub, but seems to be "out-paced", and "out-gunned" when used in conjunction with MBL 101e Mk2's. I loved what the JM Lab sub did while doing duty with my Martin Logan Quest Z's, but not so much with my MBL's.
Hence, my renewed "quest" for bigger, badder, more ferocious bass.
That having been said- any last bits of input from you fellow Audiogon members regarding which direction you might take things?
1 Fathom F212?, or 2 Fathom F113's in a master-slave configuration? (again, my room is 15'w. x 18'd. with 9 foot ceilings).
Thanks to all who have contributed input so far.

Hello Coloneltushfinger. Right on! Our listening rooms are very close to the same size. Get back to me, and this thread once you've got them set up and dialed in. Be interested to read what your experience is once you've lived with them for a bit. Still have not yet got those JL Audio subs myself, but your input will be welcomed and much appreciated. Rock on brother!
