JL Audio Fathom 13" Sub - Page 224

post #6691 of 6762
Dangitall, it started making noise. Guess I'll email JL and see what they have to say. I'll just switch it with one of the rear subs which are only turned on for movies - the front pair are always on when the stereo is on. It seems the noise only comes when the power is on for a while. Maybe some component is overheating or something.

I feel for you as I had four JL F-113's about a year ago(bought used)so no warranty.
Jl wanted a grand to have me ship from Alberta to them.
And as luck would have it one JL I couldn't bring the vol up past a whisper and she finally gave up,another just stopped completely.
Not impressed at all either.
On the bright side I got to audition a different sub at one of my audio stores.
I couldn't see what he had in there as he wanted me to here this bluray concert (Jeff Beck's)live at Ronnie Scott's).
I was blown away be how real the sound was,it was almost like being in that club.
I've never heard drums sound like drums as I did on that afternoon.
The dealer was demoing the 1812 sub(he had acquired quite a few of them.
He showed me what sub it was and I haven't heard anything like that anywhere,my lat two JL's sound like car audio subs,a major difference.
IHe gave me a copy of that disc to try out at home,I did and it totally sucked with the Jl's.
When I had called him,I had said it was probably the size of my small room compared to his which was three times the size.
His response was,it doesn't matter the size of the room.
I asked if it was possible to do a home audition(3hr)drive round trip.
We'll he brought the sub up on Sunday,set her up midway in my 12X19X7 room,put the disc in and played the track I demoed,within 5 seconds I yelled out that's it,that's the sound.
Couldn't believe I could get that type of superb bottom end in my room.
The 1812 has been here since and she's not going anywhere,the JL's where gone the day after the 1812 showed me what superb bottom end should sound like,LOL,plus the dealer gave me a lifetime warranty to boot.
Even though I was pissed with JL's subs crapping out I would never have gotten to audition the 1812.
It was worth losing out on the four JL's as I got a major upgrade musically with the 1812.
I had thought the Jl's were good,but nothing I have heard compares to this if you can find one anymore as they are that good.
They were pricey in the day and they are big,plus they are around 300lbs.
Obviously I'd never buy a JL even if it was new,as until I auditioned the Velodyne,I didn't have a clue what I was missing,end of story:D.

"Story" and " I didn't have a clue" are the key elements in this little piece of fiction. rolleyes.gif

After I recovered from trying to decipher the English in drummer's post, I realized he appears to be talking about a $20k sub. biggrin.gif With no size constraints, I'm certain one could do far better than that monstrosity, and for a lot less cash.

Definitely do feel sorry for you guys up north with all the problems, but that simply doesn't seem to match most people's experiences with the Fathoms. This thread would be loaded with complaints by now...

Congrats on the new subs you have, I was just reading your thread. Now THAT sounds impressive.

I'm not sure if us canucks got the "b" stock but here's hoping it's not ridiculous to fix.

I'm sure it can get fixed, but the question is at what price? You likely need to change out both the DSP and AMP.

I wouldn't let Gemsen do the repair at all and insist on having JL do it.

True, I guess more time will tell but of all the issues that do prop up and get reported, majority lead to defective electronics. Hopefully JL learned from these earlier defective units to make improvements in the electronics quality.

No faith in Gemsen? I'm not sure I want to pay for the freight to JL in Florida and back....

But if it's the dsp and amp that is probably a kilobuck right there if not more. I'll just swap it with one of my rear subs and use it only for movies.

I'll be glad to discuss in detail my mishaps via PM, but let's just say Gemsen's facilities are mainly equipped as a warehouse and not as service center. There was an issue with my repair but i'll just say it was resolved.

Yeah that price probably be about right. I wouln't want to ship these out either. It maybe even worthwhile to get the parts from JL and do the repair yourself?

One of my F113s is suddenly not powering up. I have discounted everything, swapped power cord and confirmed the power outlet is delivering power. Any other tips before I organise a repair?

Is there an accessible main power fuse around the back? if so unplug it and wait 10 min and check it.
post #6703 of 6762
Thx audiofan1 - unfortunately there is no accessible fuse from the back/amp plate.
post #6704 of 6762
I went with a pair of dual fathom F212 and they are vastly more powerful than I actually run them at. I like that i wont be overdriving them... Ever. Really the rattles in the room are very important to control sometimes as greater issue as opposed to worrying about subwoofer quality details.

The only time i found i could push them too hard is on an occasional test tone... But its rare that you would be listening to a sinewave. By push too hard i mean you can hear the driver movement but not necessarily get to max excursion.

I cross the system over at 80hz and let audyssey on the processor do the sub EQ although i havent exhaustively tried to use the fathom's eq system first. I also have not tried to slave the second sub to the first and run them in "mono" with the sub's eq processor.

I still have a 60hz null i am working out in my room which seems to respond best to sitting position... But of course that affects other nulls in the upper/mid bass region... So its hard to tell what to do exactly.
post #6705 of 6762
I know exactly what your problem is as I have had 2 F113's go down in the same fashion. You need to contact Barry Ober @ Soundoctor who is JL's tech. 336-347-7002. I am in the midst of my second F113 situation. It is one of 2-3 things that go on them. How old is yours? I am guessing it is probably shortly after the warranty period as that is when both of mine have blown.

My first one cost me about $1K to have repaired. My first one had a part that is affixed to the amp board on the back plate requiring the entire back plate to be replaced to repair it. You can't do it at home either as it requires special tools to remove the back panel to replace that panel. It is either that or a part on the amp board, more than likely that goes bad.

Since both mine blew just outside warranty, I am not happy. I bought them about 1 year apart and it is about 1 year later after my first one blew. I have a 3rd F113 that I bought last year which will probably go out as well in about 2 years.

I do not drive mine hard, either. With 3 they don't have to work hard to get a lot of slam out of them. I also run them maybe once or twice a week, at most.

Mine happened when I shut them down and disconnected them to clean the contacts. Upon powering back up it would not come back on again.

There is no fuse in the line on these subs. Barry knows what to do and how to assist you.
post #6706 of 6762
wow for a £3000 sub I'd expect better reliability than that.
post #6707 of 6762
Strange, but I'd still expect to see a lot more posts on this issue if it were common. Guess it could be F113-specific. I have 2 F112s, both of which are over 5 years old, and never a problem. One has been powered up nearly continuously for almost 4 years now. I have always used the series-mode surge protection that Barry recommends (Surgex SA20 I believe - however my unit, which offers equivalent protection, is from Torus).
post #6708 of 6762
I agree. Very disconcerting especially just after the warranty runs out.
post #6709 of 6762
About the actual time frame both mine went out. Hope yours are better. Two 113's a year apart in mfg worries me.
post #6710 of 6762
Oh boy, well, thanks!

I thought it was a 3 year warranty on these subs (it is now, according to their website), in which case 5 years could be considered pretty good. Unfortunately, any repair requiring shipping is kind of cost prohibitive. A 3 year warranty does seem short for a premium product, but I guess I'm not exactly surprised that such a compact powerhouse could be prone to failure.
post #6711 of 6762
The F113 that has the problem is about 6 years old IIRC. Barry said it may simply be the power supply so I am hoping..... I am dropping it off to my local service centre today.
post #6712 of 6762
Guys,

Any issues if I lay the sub lay on its side? I am thinking about building a cabinet so the the sub can be inside (except the front grill) and the center speaker will be on top of the cabinet. The extra 3" inch in less height will help a lot since my screen is right at that drop limit. The cabinet will have the end side completely open and the sub will be firing side way and not direct to the audience sitting at the sofa.



Thanks,
TT

It shouldnt hurt anything except maybe the finish. Will work fine since it is a sealed sub.

Thanks. It will sit on a nice rag and be pampered:p

Does anybody knows if there is any way to reset ARO calibration to factory setting ?
post #6716 of 6762
Doubt there even is a "factory calibration" since it would serve no purpose, except maybe to test the calibration system. Are you looking to just zero it out so it sounds the same on or off? Doubt there is any way to do that.
Mine are always set to off since I use an AntiMode, so I figure less circuitry in the signal path is the way to go. One of them does sometimes activate ARO itself after power outages, so it can be an annoyance, and I've gotten into the habit of checking for the red LEDs, which are pretty easily visible, even behind the grills.

My F113 ended up needing a new power supply - couple of hundreds of dollars and I am back in business.

Great news, glad you are up and running again!
post #6719 of 6762
Yes, good news, Stephen. Thanks for the update.

So I gather this was not a repair you could have done yourself; it required a visit to the service center?
post #6720 of 6762
I just removed a fixed screen projector and bought a motorized screen for the living room. I am taking back my living room which includes moving the towers OMD28 Mirage to the office and experimenting with sound bar. rolleyes.gif Right now the sub is next to the center channel.

I want to move the sub to the opposite end of the room (room is 13x21, screen sits on the 13ft width). I am looking to extent my shelves down to the floor as much as possible to accommodate the sub (see pic). The opening of the shelve will be made to fit the sub.

Question for you guys. Since the back end of the shelves is part of the closet in the bedroom on the other side of the house, would the sound bounce and make sonic noise biggrin.gif . The front of the sub will sit flush to the wall firing out. I am guessing it should be fine since it is a sealed sub.



Thanks for reading.

Tt
