JL Audio Fathom 12" Sub - Page 5

post #121 of 417
It will be an upgrade from an SPL standpoint, but keep in mind you are paying a premium for the smaller, sealed enclosure. And the enclosure is certainly well built and has a high WAF.

From a SQ standpoint, there are many who feel that the Fathom will be superior. However, one member did not seem to notice that much of a difference between his SVS and Fathom. However, you are better off listening and deciding for yourself.

When you say SPL standpoint i am assuming that it will give me more output? What about the lower regions? How does it compare to the 2039pc+

Will it be an upgrade at all? What should I expect?

And upgrade at all!?

Of course it will be an upgrade. From the sound quality,built and design it is on a whole new level. If you had a SVS Ultra it would be closer in performance but the f112 is worth the extra expense.

No matter how you push a Jl it will never suffer from any port chuffing,port noise of any kind.The control in the bass is greater.The cabinet as inert as they come and the ARO will even out the response.

This not taking into account the looks and feel of the sub.It is a total package.

Go listen,I would compare A/B on HT and music. It not only moves a good deal of air,it does so with total control.In my vie the Fathom subs are the finest compact subs made.They do not suffer from lack of displacement when compared to often much larger designs.

I am going to use it for 95% movies. What is the F112 native tuned hz at? I will see if there is a dealer in my area that will do an in home demo.

It's a sealed box, so it doesn't have ports or PR's that are tuned to a specific frequency. It's -3dB point is 21 Hz, but because it's a sealed box, the rolloff is more gradual than a ported or PR design.

Since I will be using the sub for movies so will it still reach pretty low with good output? I will be coming from a 2039pc+ currently running at it's native 20hz.

YES

The Fathoms are known for very impressive output down deep,and superb SQ.This is THE reason why I went with a second and third one.I was enchanted by the level of efortless deep bass comming out of these small boxes.

The drivers used in the Fathom subs are some of the highest displacement in commercial subs.Size to size they have little competition.

Anybody here from the Bay Area? Dang I really want to go hear this sub.

I went to the website and called a Dealer in Monterey and their phone just rang that went to voicemail (maybe a custom install only-no auditions available) and I called a shop in San Jose and they stated it was incredible but didn't have it available to audition but would gladly order it for me.

I just purchased new Dynaudio Speakers and I am looking for a great quality sub to match for music/movies. I wan't a smaller sub and this seems to fit the bill.

I love the shop that I purchased my speakers from but they are a REL shop. The REL's sounded very good to me but I want to explore my options. I think I would appreciate the JL during set-up.

My new speakers should be here next week and I would love to get my sub settled. If I can't find a real audition I am thinking of ordering blind.

If anyone here is from the Bay Area, kindly let me know where you purchased if possible. If not I will need to make the decision on a blind buy but I don't think this would be as drastic as a blind main speaker buy.

Thanks..

Ya... anyone around Cerritos, CA care to demo their f112? I would bring my svs to hear a comparison.

Well Dick the simple answer is you don't. But some people have difficulty separating their wants from their needs.

Why?

Because I have two f113 's in a larger room and a f112 in a smaller room. And because I like to have extra headroom.

I almost never listen at over 90dB (listening position),so yes you would be correct to say the second sub would not be needed.

Why not? Some people buy cars capable of over 200MPH,will they use them...most owners not even close.Buy why not? If people purchased just what they need,the world would be a boring place to live in(and probably alot healthier too).

Relax Ear... Nothing wrong with having more or "WHY THE HECK NOT".

Just pointing out that you don't "need" 3 or in your case 30. That falls more in the "want" side of the equation.

Besides the silly responses you received above, there are two primary reasons to have more than one sub:

1. Greater total output. If you co-locate the subs, you'll get ~6 dB of greater output, (on average) with two subs over 1. If they're not co-located, (i.e., seperated by some distance), you get ~ 3 dB of gain.

2. Smoother frequency response over more seating locations. With 2 sources of bass, you're less likely to have peaks and nulls at any seating location. Also, the peaks and nulls will generally be less steep. (Obviously, this is very much setup dependant).

I have a question for those with JL Audio Fathoms. I was reading the manual ( interested in getting a pair ) and wanted to know how the connections are done if you have two F112 each with XLR connections back to the Processor and want to use the master/slave combination.

The manual states that you plug the output slave to the input balance mono.

The question I have is that I want to run two xlr runs from the processor for L/R to the pair of F112's for regular 2 channel stereo. If I am using the XLR's for that purpose, how would you end up connecting things for the master/slaver operation of the units.

The manual keeps referencing back to the same page (from diagram 4 to diagram 2 ) but doesn't go over that detail.

Thanks!

Raf,

If you connect the two subwoofers in stereo, they cannot be in master/slave. You would need to calibrate each one individually.

How does that affect the calibration of both units? Any particular things I should be concerned about in this type of setup? I would have thought that with 2 units, running two separate runs of cables would have been a better configuration.

Thanks!

I'm not sure I understand the question, Raf. Do you want stereo sub-bass? Or is mono sub-bass acceptable?

I do want stereo bass. Let me re-phrase; since I would have to do the calibration of each one independent, what would I loose in regards to the accuracy of the calibration? It would seem from what I read that the best method of calibration is done via master/slave method.

Is this simply from simplicity? Or is there an additional level of accuracy that is enabled in M/S mode.

Thanks!
Raf
post #141 of 417
Okay, RAF...

The master/slave configuration assumes a mono subwoofer configuration and seeks to calibrate all of the subwoofers together as a single system (using the master sub's processing and passing that signal to the slave subs). When applying multiple subs in mono as is typical in an HT system this is the best method for applying ARO and getting optimal response. The output from the master is identical to the signal feeding the master's amp, which is a mono signal.

If you want stereo bass, place one sub on the left and one on the right as close to your mains as possible and calibrate ARO for each sub independently.

Does anyone use the ol F112 anymore, or has everyone decide to just go for the bigger brother?
post #143 of 417
Are you kidding? Are you asking maybe because there isn't much action on this thread? I have twin f112's and can't imagine having/needing f113s. They are perfect for my HT and just amazing every time I crank them up.

post #144 of 417
I have two f112's as well... no regrets, no envy.
post #145 of 417
Mr Smith,
I live in the UK and I am very interested in the F112 and the F110.
I understand that your subs are only 110v, is that correct?
Do you have any customers in the 220/240v area? Is it possible to use them with a voltage converter and in this case would there be a decrease in performance? Do you have any plans for distribution outside America?

Feedback from any overseas users would be very much appreciated.

I have a 14'x17' dedicated HT(90% movies) with an old 8" Velodyne sub. Time to upgrade!! It's the weak point of my system. I've got an AVM 50 on the way, Anthem A5 and Bryston 5b amps and Thiel MCS 1 lcr's. I've been drooling over the descriptions of the F112(and F113), and I've read that 2 subs are best because you get balanced and non-directional bass, etc, etc, but there is NO Way I can afford 2 F112s. So, I thought of a couple different solutions and would love some feedback.
1) just get one F112, it'll be more than fine and you'll just love it.
2) yes, 2 subs are (almost) a must, so get one F112 and one less expensive sub like an HSU. (I know that main and surround speakers should be from same maker, is that the case with subs, too, so this option is NFG?)
3) Rob a bank and get enough $$ to buy 4 F113s and sound-blast the cops when they come to arrest you.
4) Other ideas?

Any suggestions are appreciated. Thanks
post #147 of 417
I like option 3! HAha,

Seriously though, the F112 will be a huge leap in performance over your old sub. Your room is not too big, so a single F112 should be more than enough. I wouldn't bother mixing the F112 with another sub.

Another option would be the new Ultra from SVS. It is around $1500 and should very good performance. But it will be a much larger sub than the F112.

Start with #1. Think long and hard about #2. Avoid #3 as you won't be able to enjoy your sub(s) from jail.

Seriously, I have an F112 in room larger than yours with openings to other spaces. It's just fine, and like *loud* bass.
