Why so many JL Audio Fathom subs for sale I wonder

To its ability to output well defined extra low frequency the JL can do an outstanding job. I've heard their technical support can be very helpful. The JL Audio Automatic Room Optimization is very useable but may need updating. The JLs brut force paired with an Audyssey system or similar, would make it a contemporary world class performer.

Understandably, the failure to successfully integrate a subwoofer by selecting a favorite recording with deep bass content and simply adjusting the crossover, volume, and location is stunningly outmoded.

I've been in many post production studios and all of them use a sub/s. With decent low frequency room equalization almost any subwoofer can be a useful addition to almost any system IMO.

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.

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?

I had them as independent at one point when running Ming Da pre and two Linn Klouts. Things changed and now they are running together through a modified Onkyo reciever. Running the ARO as separate or in master didn't seem to make that much difference in my room so I set the left as the master.

After listening to all the JL's and reading about multiple subs vs. single subs I just felt that two F113's placed right next to each main made sense. I ran this by a factory rep and he said either two F212's or two F113's in my room should work well. Two F212's were out of the question.

In the demo room the differences were minor until you started running into the 90db range and this is where two F113's started to shine over the one F212. Just a stronger grip over all and a little more slam. They were both crossed at 80hz, eq set to zero on pre with -3db on 25hz and lower. Volume was set to ref and the two F113's could have been dialed back slightly.

The stage these produce is pretty stunning so either way you decide should work very well.
