Subwoofer SVS SB13Ultra vs JL Fathom F110V2


Considering a new sb13u vs a demo F110v2 to mate with my Martin Logan Vistas.  Room is 11x19x8 with one side open to a great room 16x26.

Anyone have experience with both?  I currently have a REL T5 that is great but just too small

Thanks

I had dual SB13 Ultra's in a two channel system and sold them for dual JL Audio F110 V2s. My friend has a single SVS 13 Ultra and once he heard the JL Audio F110 V2s he put his SVS 13 Ultra up for sale. I'll send you a PM with my number if you would like to talk about the differences.
Thanks Ricred1, 
That is the kind of feedback I was looking for.  What main speaker are you and your friend using?

I can only get one now and add a second later.

My system: Aerial 7ts, Jeff Rowland(JR) 625 S2 amp, JR Corus preamp, JR Aeris DAC, Bryston BDP-2, JL Audio CR-1 and F110 V2s.

My friend has a surround sound system with Dynaudio Audio Focus speakers(I believe 240s or 260s).

I will tell you the CR-1 makes a significant difference.
Thanks again Ricred1,

Do you mind elaborating on the difference between the sb13s and f110s. Do the F110s seem to go as low as the sb13s?    Budget only allows for 1 of wither right now but either way I plan on experimenting with the crossover built into my NAD C390dd

Thanks again
I'll preface my comments with in my system and in my room! The F110s are more articulate/tighter, provides more air, deeper, and play louder. Unfortunately, it isn't even close, because if it were I would have kept my SVS 13 Ultras.
Adding the CR-1 is a game changer! Everything and I mean everything is improved...more defined bass, wider soundstage, better imaging, "more AIR" and just a relaxation to the music being played!
Ricred,

I'm just curious as to the size of your space.  From the test data that I've seen, a pair of Ultras offers enormous clean output capability.  Your observation that the JL does better on that front (and, to be clear, Im not contesting that observation) suggests either a huge space or crushing SPLs (or your Ultras not delivering what the test pair did).

BTW, test data is available at hits hack.com.
Damn autocorrect:

That was supposed to read:. Htshack.com
Hi Jl Audio Dealer, here, the SVS does offer a lot of output, however, build quality and articulation is in the JL Audio Camp. The New V2 woofers are fantastic, I do have a demo F113 at an attractive price. 
Thanks.  Given they way some are describing the extension and output of the F110 i can only surmise the published specs are rather conservative.  Is that accurate?
martykl,

I have an L-shaped room: w= 20', L= 24', back wall 26'(L).

I'm not a dealer and haven't completed any measurements. I can't see anyone hearing both subs in the same room/system and not hearing the differences between the SB13 Ultra and the JL Audio F110 V2s.
Thanks for all your input ricred1. Your comments are very helpful. That is an awfully big space.  Its great to know that the smaller 10" drivers move that much air.

Cheers

one other sub to consider, especially if you have a large room, is Seaton Sound.  I've owned subs from Velodyne, Vandersteen, JL Audio, SVS, and now Seaton, and find that my F2 outperforms all of them.  Absolutely nothing wrong with the others, especially JL and SVS, but I find the Seaton to be better all around.
Thanks. Information on Seaton seems hard to find.  Their website does not seem to be up.  Their forum is up and has some information.  Is there a source for information on Seaton?  

Im also expanding my horizons to include Rhythmic f12 and the JL e110.

Anybody have any input on those
Rythmik also has a loyal following - I was considering the F15HP when I purchased my Seaton F2.  I'm sure it's another fine option, but I have absolutely no regrets nor desire to try any other subs since integrating my F2.  It's an amazing sub.

The Seaton website is in progress, but as you noted the forum is updated and you can always call them at  773-290-8436.  You could also email, though it may be a day or two to get a response.  I've always found them to be great to work with on the phone.
I had a single JL F110 for a mid sized room and it did a pretty darn good job, but ultimately it didn't have the really deep bass I was looking for.  It was very articulate and fast.  If you have a large room, I highly recommend going with the F112 or F113, the F110 won't do it justice in my experience.  This also depends on the type of music you play and volume.  

I ended up selling my F110 and bought a Rythmik 12" with GR Research drivers and I'm happy as a clam with the improvement.  With the servo technology, it sounds very linear and tight and goes lots lower than my F110.  I purchased mine through Jim Salk, who improves the internal bracing, a thicker cabinet, and custom veneers.  My plan is to get another one.  My buddy let me borrow his dual subs and after that experience, I gotta have duals.

erndog,

Thanks for the input.  what main speakers are you using and how big is your room?  Was the difference between the rythmik and the f110.  Are the Saulk versions that much better than the standard rythmik? 

My room is 23'x13.5' and my speakers are Coincident Total Eclipse II's.  I spent 3 weeks listening to the standard version and loved it, but returned it because of the industrial look of the sub.  Salk is building me a sub as we speak with a dyed maple burl in high gloss.  It looks like gorgeous art, which matches better with my main speakers and my home.  It should be ready in a month, so I haven't heard it yet.  

I did notice that there was lots of vibration on the standard version, when I put my hand on top of it during moderate use.  I believe that is the reason Salk focused his version on bolstering this area.  Jim said that his upgrade reduces this so there is hardly any vibrations.  Now whether this can be discerned from the listening chair, I can't say.

I found both the F110 and Rythmik F12G to be very tuneful and musical subs.  The biggest difference was that the F12G had more output and easily reached depths that the F110 couldn't touch.  I loved the auto EQ the F110 has, which the F12G doesn't.  The F110 looks gorgeous, but also cost a lot more.

 My bias is that I love bass.  When I play the Eagles live cd or powerful classical music, I want it to sound realistic.  I like to tune subs so that they don't draw attention to themselves, like you don't even know they are on, until you switch them off and then you can tell.
I don't know how much difference there is between the F110 and F110 V2, but it appears that erndog and srosenberg are not talking about the current JL Audio F110 V2. That being said, I like to repeat, "there are no absolutes in Audio, only preferences."
Right, the V2 has not been out all that long so I presumed other comparisons were to the v1.  From the website it appears as though the amp is new on the V2 as is the DARO room correction process. Not sure what else they changed.  All specs seem to be the same except for the weight which probably accounts for the new, more powerful amp.

Did you find the DARO useful?  Does it work with dual subs?

ctro---Jim Salk puts the Rythmik guts (15" servo-feedback woofer and 600w plate amp combo) into his own sealed enclosure, which has much more bracing than the Rythmik box and greater internal volume (4cu.ft. versus Rythmik's 3cu.ft.), for more efficiency and slightly more output. Jim offers the sub with beautiful wood finishes. The Ryhtmik guts are also available as a DIY kit, and you can have your own box made from the plans on the Rythmik site.

But for use with planars such as your M-L's, the sub to get is the OB/Dipole sub, co-designed by Rythmik's Brian Ding and Danny Richie of GR Research. It mates with planar speakers better than ANY other sub, regardless of price. Remember the dipole sub Gradient made for the QUAD ESL63? Picture that, but with far better woofers featuring servo feedback control. Not as much sound OUTPUT as sealed or ported subs, but superior sound QUALITY. If that's what you're looking for.

Great suggestion bdp24. I’ve never heard the OB/Dipole sub, but there is a growing camp on the AudioCircle forum that swear by them. It would be fun to demo these and hear what all the hoopla is about. I understand they sound best in larger rooms.

Also would be fun to demo the new Fathom V2 to hear how it compares to the original.  And I can't leave out the E112 to demo too.  Gosh I need to retire so I can have enough time for my hobby.
Ha yes. this is the most satisfying and frustrating hobby of all.  tough for those of us who lean toward obsessive compulsive.  But that is what makes it fun.  

erndog, the OB/Dipole sub needs to be placed as all dipoles do---not less than three feet from the wall behind them. If they are paired with dipole main speakers, no problem, as the speakers are already there. They can, however, be placed right up against a side wall, as there is a null to each side, a result of the front and back wave cancellation. The OB sub, by the way, uses the same woofer as that of the Rythmik F12G, but optimized for Open Baffle use. It can be used as not only a sub, but also a woofer, crossed over as high as 300Hz.

The sub sounds quite different from sealed and ported subs, without the room-loading boom, fatness/thickness, and all-too-often "lagging-behind-the-speaker" sound of them. They have the "start and stop on a dime" sound we all want. Leaner, cleaner, more transparent, like the bass produced by the 3-panel Maggies---the Tympani T-IV and T-IVa---but with far more output, far less distortion, and far deeper response. The woofers are not only NOT loaded into a bloat-producing box, but are controlled by the Rythmik Direct-Servo-Feedback system included in the plate amp. An Open Baffle woofer with servo-control---the only one in the world, and a game changer imo!

Imagine the sound of an open baffle loudspeaker, but with response into teen frequencies. The way it reproduces the woody resonance, growl, and percussive "plunk" of the acoustic stand-up bass (whose open-E string produces a 42Hz tone) is unmatched, in my experience, the fundamental (produced by the sub) and it’s harmonics (produced by the loudspeaker) in complete sync. The left-hand registers of a grand piano are just as clean as the right. The OB sub doesn’t sound like a subwoofer has been tacked onto the bottom of your speaker, it’s response trailing behind the speaker’s like the caboose on the end of a train. It instead makes your speaker sound as if it’s response has been extended down into the very lowest frequencies, leaving the speaker's character unchanged and intact. Isn’t that what you want a sub to do?!
