Title: JL F112 to Fv15hp to Seaton F18i
Post by: yanwei on January 04, 2019, 21:36
Hi guys, just wanted to ask if a used jl audio f112v1 is still a good buy at this point in time? Or should I be looking at other subs?

My room is 3m x 4m. I have a kk808 sitting on the 3m side of the room. It does the midbass job well but I can't help but notice that I'm missing the low low rumble like those 15 and 18 " sub can do easily.

Should I get the f112 and put it on the other side of the 3m wall, and relocate the kk8 to be diagonally opposite the f112? A 15" sub would be very tight to fit in the room. May need to close the gap between left and right speakers.

The new Starke SUB 36 is a good beast to explore also.

Hi bro. I have also read about Seaton but have not heard it. Is the Seaton F2 and slave F2 too much for my room? If not, it would be nice aestically to put one each on left and right beside the wall. Height wise they would be same height as my bookshelf speakers. Lol. F18 would cause my left and right speakers to be much too close to center speaker.

I do like the option of bigger sealed subs to get the bass pressure, but only worried about whether it fits.

BTW, is there a local dealer for Seaton sub? Or have to order direct from US?

Or how about 2 js-12 in the front left and right corners? I did some measuring and they fit nicely by allowing the left and right speakers to still be within one foot of the projector screen edge. The F2 will cause the speakers to shift further within the screen or too close to the walls.

Does a pair of these js-12 perform better than the F112 that I'm considering? Do you think it can pressurise the room and go till 10hz?
And also if used in conjunction with the kk8 stack on top of the js-12 can we get kan cheong bass? Hehe.

I saw in the other thread someone mentioned the the quote for 2 js-12 is about 3k with shipping? This is definitely cheaper than 2 f112....

The JL audio will perform well if you don't listen too loudly... It has physical limitations due to low efficiency driver, small sealed cab - lots of EQ applied to boost the low end and therefore the limiters kick in at higher volumes and low frequency. The amp and driver runs out of headroom. Here's a measurement of the F113.

A pair of seatons F2 should have slightly better headroom, but not sure exactly how much.

If you never hit the limiters on the F112, then it will be very very nice too. Just depends on how much you like your bass haha. Do you enjoy movies, or just play bass demo scenes until your subs cry surrender?

Sevens has a pair of E112 after owning Kk and Rythmik. He's happy with it, does both sealed and low bass well. (https://uploads.tapatalk-cdn.com/20190106/50e3be6f49788e07c6f60f1d7fa72b17.jpg)

Bottom line... 2 subwoofers for JL Audio is always recommended if you intend to go with JL Audio.

Thanks for all the replies. Did some more reading and especially on the Seaton forum. Most likely either going for dual js-12 or one F2+ for now and another slave F2 in the near future.
I think I will have upgrade-itis if I went the jl audio path.
Will update when the new subs have arrived.

The seatons are absolute class, very clean sounding, a lot of it is to do with the subwoofer amplifier, the subs can dig deep, with some in room extension you can achieve down to 12hz. I highly recommend the F18s, main reason why my Mrs allows me to keep 4 is because it sounds so clean down Low that it doesn’t irritate her with the boomy bang bang .. but not everyone’s cup of tea, some would prefer the hard hitting bang bang type of bass, for me I’m very happy with the subs, no regrets

If u push the subs further for deep bass with higher SPLs, u will start to get goosebumps, energy hits once, hair will stand once, hit again stand again... yet not annoying to neighbours, very addictive ...

I haven’t heard the JS-12, was looking forward, then Friend backed out and got the starke instead...

Remember one thing when u pick subs, it’s important the subs can dig deep down to at least 15hz, most of the LFE recordings are from 18-35hz, this area of frequencies are the ones that will create the “syok”. Most Hollywood movies have very deep bass, less focus on midbass. Only those HK movies mostly focus on midbass. Another thing u need to be wary when picking up subs is to go for one that can dig deep, if the subs can dig deep, it can naturally handle midbass, may not be like the midbass modules, but will provide the midbass. A midbass strong sub however, can only do midbass and that’s it. It cannot go Low...so u will find something missing.

I’d be happy to host u if you wanna have a listen on the seatons... but that would have to come in end February after I’ve completed my entire HT revamp...

PM me if u r keen, I’ll arrange a day for u...

If need to get a sub which dig deep then another SB2000 or 2 x SW-12 should not be in my consideration? Currently using SB12-NSD and thought of going dual.

No idea bro on the subs u mentioned, I can vouch for the seatons and rythmiks as I’ve owned them, rythmiks with servo is very good as well, especially the f18, it not only produce clean deep bass, but with speed and accuracy. But most importantly , u must like the sound signature, that’s the first priority above all

Post by: rayleh on January 07, 2019, 18:54
Really appreciate your response. I will audit the subs. I can get 2 smaller dual subs or bigger sub, can’t have both world due to space constraint. Most likely will go for dual subs as read many fave reviews of dual subs.

Bro ronildoq, thanks for the invite. I'll definitely pay you a visit when your reno is complete. Been looking forward to listening to your setup and also can learn from you the house curve settings. I have been following your thread and instead of using the Dirac target curve, I am using your instructions on how to create a house curve. There's a huge improvement but I think the kk8 is not able to supply low bass that's why I want something bigger.

Initially I wanted svs subs to match with the rest of the speakers which are svs. But after reading some reviews and comments that ppl who have upgraded from rythmik, svs, jl, they find that Seaton offers more for less money.

Theb when I read your posts about kan cheong bass and bass that can be felt and not heard hence not too neighbour unfriendly, all this makes me want to experience your setup.

I have further realised that I can fit 1 Seaton HPi+ and slave so I will most likely be going that path. Now just waiting for the quote from Mark. It will be a blind buy but I think should be safe since I'm used to sealed sub like kk8 already. And I want more deep tissue massage!

That was my initial thinking before I heard about Seaton subs since my entire setup including height speakers was Svs. Now I think I want to go for the 15" Seatons since they fit and I can get 4 15" drivers in the room without pissing off the wife.

I’m sure this investment will bring you a big smile , the pairing with kk8 would be awesome , High pass the kk8 for upper midbass only, and enjoy the best of both worlds with fast deep bass and attacking midbass... I’ve tried this combination before, it’s a match made in heaven

I’ll Pm you when my place is ready... just collecting a few more panels today to work as atmos diffusors

You gotta be very patient with mark, he is slow with response , try contacting him on FAcebook instead, he is quite responsive there

But the wait is worth it....

I'd advise against going with Seaton unless you are willing to go on long waits without notice from Mark. From payment to delivery, took 6 months for me. I recently got the first 2 pairs of the new F18i subs from him, with the new amps we no longer require to run master slave. It's really frustrating for a local who is used to getting things fast and having visibility of the project. What's good about buying from Mark is the price and the sub performance. His price w/ freight is probably the lowest, other than black friday JTR sales, if you're buying 18" subs direct from USA and as pointed above, the subs are really of good quality and packaging is 'bullet proof'. If you can wait, and have the patience then you won't be disappointed, but take note that many on avsforum are still waiting on Mark to respond to them too. FB messaging works best for me. I hope this helps? I feel that you should consider local option or audition others first before sinking the money.

Wow, that is a rather unfortunate experience, I’m really lucky indeed, I ordered twice, first batch master slave, it arrived within 3 weeks, shipping was 1 week with customs clearance. Second batch master slave f18 again, but took 1 month to arrive . 6 months for u is like way too Long.

Agree with u there is always a risk when shipping overseas. Imagine if being shipped with a faulty unit with no local support, very high risk indeed.

Maybe it’s wise to check on delivery times if really keen to go for the seatons. Or some form of arrangement where deposit is paid first and the balance once u get the shipping tracking details etc...

I’ve dealt with mark on few occasions, he guided me on many aspects on subwoofer, a lot of skills were acquired in the process, nice guy. Hopefully he is able to clear his backlog and deliver goods promptly , otherwise consumers will lose confidence

Hi bro, I have just finished a lengthy conversation with Mark on FB messenger. He mentioned that the F18i will be shipped out within 3-4 weeks after ordered is placed. Hopefully should reach here by 4-6 weeks. I've placed an order for a pair of F18i as well. Hopefully it doesn't take as long to arrive.

How is the F18i working out for you? Did it meet your expectations?

Good for u man. Other than the waiting time and the slow response from him, the sub is just clean and powerful. I live in a maisonette and it has enough output to shake my bedroom windows at the 2nd floor during EOT opening scene. This is at -15 trim on my NAD after Dirac calibration. Hope things work out better for u than me.

That's great! I need to feel that missing rumble that the kk8 is not able to provide. I guess the hardest thing is the waiting. I hope to give a short review after the subs have arrived since there are not many reviews on this F18i online. Will be using Dirac to calibrate as well.

Great and happy for you ! Hope the wait is worth....

The KK is only good for midbass..... you need a sub that can dig deep for ULF, then you will feel its complete. Midbass alone is only 1/4 of the story with Ken Kreisel subs.....

The maximum SPL is not a very reliable way to judge the impact of a subwoofer, maximum extension down low on a properly time aligned subwoofer is way more critical and will bring you much greater body impact and seamless connection with the mains. This area is very important, the balance between upper and lower bass. The seatons can dig deep and with speed and accuracy down low freq, low distortion and enough headroom with extension to the single digit.... Im very sure you will love it, if you manage to bring out the best in the subs.... this means having very good time alignment between speakers and subs.... this part of the story is critical.... that is where your set up will shine

Bro,
I would suggest you spend the time to walk into KEC. Ask them to demo for you 2xSB2000 (12") vs. 1xSB4000 (13.5").
Ask them to play 2 movies, you can compare these two SVS subwoofers... then surely you will know the difference between loud bass vs deep bass.....

Just 3 more steps from KEC,  take a look JL product at Sound Decision .... beware a lot of strong poison there

But from some friends advise is to go for bigger driver and box the bigger the merrier.... :o  :o...

Mid bass should be the fast heart pounding type while low bass is the rumble type. Always feel the bigger woofer tends to be slower (theoretically need to move more air but higher SPL) so it may not be able to catch up for fast bass. I prefer tight and fast bass. Anyway my own opinion and I may be wrong, not a HT guru.

I thinks back last year I did visit KEC to demo the SB-4000 and SB-16 Ultra. During the demo the bass was good got the impact and feel of the rumble.
Than I also when to SD just a few step from KEC.
My experience with SD is that the 150 screen was impressive.. surround sound was better compare to KEC. For the bass area i don't get that impact and rumbling from what i had experience at KEC earlier...  :) :) :)

And don't forget that when the sub is finally at home, its sounds totally different from how it sounded like at the store.

In my humble opinion, I decide which sub to get by:

1) Determine what type of bass you like (mid-bass or deep low bass)
2) shortlist the subs that fit your criteria by asking here or reading extensively
3) Ask nicely if there is anyone here who can demo their home setup's sub thats in your shortlist
4) read user experiences online to gather more feedback
5) Go to the store to determine if the seller will deliver high standard of after sales service.

Different people/stores calibrate and emphasize bass differently.

Fully agree! When buying a sub, it all boils down to very 3 main fundamental
I. Users expectation - what is being expected of your very ownself, the type of bass you wanted (aka your personal taste).

2. Room modes - understand your room modes, roughly the volume as well as how big (driver size), how many qty and how low/mid you looking for. Dosent mean that if the sub don't work in a huge room volume, it also won't work in a small room volume. Maybe you heard the sub perform well at one place, it may or may not also perform the same at your place


3. All brands are good brands - don't belittle sub branding if the sub cannot perform since it drills down to point 1 and point 2. Each sub have their own strength when marry with the correct room modes and placing.

I'm on DIY sub for coming 5 years. Another 2 more midbass coming in later today, also diy. Let's call it OU subs :P .... I trust that the midbass sub can perform in my place since it was tuned to meet my room modes. This "bird cage" of mine may not lose to any other branding subs out in the market. Lol  ;)

Nothing wrong with asking. I presume louder bass refers to bass at high SPLs. So pretty straight forward, increase the volume and you are done. Louder Bass

Deep infrasonic bass is a different story. It’s not rumbling your seats any more. You will start to feel the ear pressure, as if you are going up a mountain or descending from airplane. The pressure will build up at ear levels

Then comes the wobbly moving around feeling as if u r on a boat, those are single digit infrasonic bass. This type of bass is very hard to achieve, u need subs that can dig deep down Low... and By saying that, I mean “Quality” subs. Yes, Quality subs. Not all subs are the same, a quality sub makes a difference . Suddenly u will feel the intensity and this why I call it “Kan Cheong “ bass... don’t know how else to describe the feeling ... the entire scene will feel so intense, some may not like it if not used to it... especially good for watching horror movies ... The conjuring !

Best part, doesn’t disturb your neighbours... Mrs no issues

Nothing wrong with asking. I presume louder bass refers to bass at high SPLs. So pretty straight forward, increase the volume and you are done. Louder Bass

Deep infrasonic bass is a different story. It’s not rumbling your seats any more. You will start to feel the ear pressure, as if you are going up a mountain or descending from airplane. The pressure will build up at ear levels

Then comes the wobbly moving around feeling as if u r on a boat, those are single digit infrasonic bass. This type of bass is very hard to achieve, u need subs that can dig deep down Low... and By saying that, I mean “Quality” subs. Yes, Quality subs. Not all subs are the same, a quality sub makes a difference . Suddenly u will feel the intensity and this why I call it “Kan Cheong “ bass... don’t know how else to describe the feeling ... the entire scene will feel so intense, some may not like it if not used to it... especially good for watching horror movies ... The conjuring !

Best part, doesn’t disturb your neighbours... Mrs no issues

Thanks Ronildoq.. your explanation on the type of bass is very detail and easy to understand...
Waiting for your invitation soon... ;D ;D ;D

Haha, not really la bro, midbass is the one that will give u the heart attack , like a needle piercing the heart if it is Super intense, Long exposures will lead to fatigue... infrasonic bass won’t... infrasonic ones will make u “feel” Kan Cheong...

You are right. I remember listening to the KK and watch The Legend. I also felt my heart giving up. So “Kan Cheong” bass is like those super spooky and suspense like watching a really scary horror movie, right?

Yea, it’s like you hear the roar of a lion, the animals get intimidated, that’s why lion is the king of the jungle... one single roar and all the animals will flee. That roar contains infrasonic bass, intense from 20hz down Low.... u can actually feel the bass when a lion roars, can’t imagine T Rex roars in the prehistoric times... of course none of us heard a real T. rex roar,  so sound mix from Engineers on T Rex roars doesn’t sound and feel right to me, especially those like the Jurassic world kinda movies... it’s just rumbling away... doesn’t sound right to me... , then again, nobody knows how a T. rex roar sounds... hahaha

Hi guys, just wanted to ask if a used jl audio f112v1 is still a good buy at this point in time? Or should I be looking at other subs?

My room is 3m x 4m. I have a kk808 sitting on the 3m side of the room. It does the midbass job well but I can't help but notice that I'm missing the low low rumble like those 15 and 18 " sub can do easily.

Should I get the f112 and put it on the other side of the 3m wall, and relocate the kk8 to be diagonally opposite the f112? A 15" sub would be very tight to fit in the room. May need to close the gap between left and right speakers.

I feel that with F112 price point, you can get another dual sub setup or another big single sub that can go very low e.g seaton 15" or 18". Suggest not to go with F112.  =)

Yeah. I also think so. But the F112 I mentioned was used so the price not so bad. In the end, after reading some of the comments and also some reviews, I decided to go with dual Seaton F18.

Now waiting for the subs to arrive (supposedly 3 weeks to ship out and another 1 week to arrive) and also waiting to visit bro ronildoq place to experience the kan cheong bass.

If possible go for dual subs, it will make a significant diff.

Yes bro. I am now waiting for Mark to ship the two F18i. Coming from a single kk, I always feel I can sort of localise where my sub is during bass scenes even after Dirac calibration. This time round, I don't think there will be such issues. I'm planning to place the two subs in front left and right of the room since no other space to put two 18" monster subs liao. No sub crawl or anything.

Has anyone heard the deep sea sound mariana? Just noticed that they have a 18" sub that measures 3 " shorter in width and height. Slightly more expensive than the F18 at 2.4k usd each.

Post by: yanwei on January 28, 2019, 01:00
Just an update:
Mark will be shipping out the 2 F18i this week. Hopefully the subs will reach here in another week's time.

I also got a fv15hp from peng to pair with the kk8 for the time being. The low bass from the rythmik is nice! Can't believe my ears when I watched Edge of tomorrow starting scene. Explosions now have a very nice hard punch from the kk followed by the low rumble from the fv15hp.

This makes me wonder if I can place the kk8 behind the center speaker and the 2 F18i flanking the left and right speakers. This is to keep the attack from the kk and the lowness from the F18 together.
Title: Re: JL F112 still a good buy?
Post by: ronildoq on January 28, 2019, 08:36
You might have a problem pairing the KK808 with the seatons, pretty sure the KK808 cannot cope, I was having the kk12, it couldn’t cope with the f18, and I was using rythmik fv15hp well, 3 different makes, one each to handle a specific frequency

The good with this:
1) initially it felt as if all is good, each handling a specific frequency where it’s strong. It gave all the necessary Low rumble, speed from midbass and depth

The problems
1) very difficult and time consuming to integrate the 3, one of it being ported
2) the mix of the sounds from 3 different make gave a “rojak” sound, coherence was missing though measurements in the amplitude response was good
3) fatigue after Long run. It just hits and go, just SPLs , no proper  bass imaging due to lack of coherence
4) time aligning with mains was a another headache
5) couldn’t push the kk12 subs as it bottoms up despite a high pass filter, the lower subs was bringing the entire system down

I went through the above process 11/2 years back, in the end I sold my kk and rythmik and got in another pair of seatons f18. No turning back after that

Trust me the seatons can pound with speed, u just need the right placement and EQ to bring out the best.

Congrats on your pair ! Let me know if u need help, I’m familiar with the f18

Just a quick update:
Duo F18 have shipped today. Estimated arrival is next Thursday. Shipping weight: 254lbs omg crazy weight.

When these two arrive, the kk8 will be sold and the rythmik fv15hp will be shifted to parents room. This way, we will just need to deal with 2 F18 in the room.

Congratulations! That’s not too bad for the waiting time :) happy for u, time to enjoy soon . There is a LF knob at the back, use it post EQ to boost deep bass from 30hz down for the electrostatic goosebumps

Ya! Heng no need wait too long. A bit kan cheong dealing with Mark because he's a one man show and we're used to efficiency like Peng or KEC kind where you order and stuff arrive quickly. Anyway, the new amp is ice power so don't know how different is it compared to the speaker power master slave amp. Now both subs will have its own amp.

congrats bro! Nice, SEATON makes awesome subs (Sadly not so renowned in SG)
and IMO, is THE SUB to beat :D

Haha. I hope so also, if bro ronildoq using 4 of them and they can satisfy him (for now) then you know these are very good subs.

Just watched overlord with my wife last night using the kk8 and fv15hp and bass very shiok liao. She say want to watch again. So hopefully next week when the 2 subs arrive then we'll rewatch overlord on it to feel the difference.

Nice ! I’m waiting to watch that one, waiting for the HDR version and to finish the calibration works this weekend for the Lyngdorf. The zombie ones will have lotsa Kan Cheong scenes ... haha

The subs would have been run in at factory, so it can go straight in for EQ with the system...

You might wanna use A lower LF before EQ( maybe 2 steps on the dial) ,  don’t let whatever EQ programme u r using attenuate the deep bass. After eq then u use the LF boost accordingly

Enjoy !!

How to know which have hdr? The ones I get usually say uhd together with Atmos. My projector only fhd so I can't view 4k anyway.

The knob you mean turn anti clockwise first then run Dirac calibration? I thought usually the knob is turned when setting mic gain and then see if the test tone is within limits.

Subs are now in Narita!

What u don’t want is set this too high for the EQ programme to cut it away.... so use a lower boost, 1-2 steps... then run EQ. You can bump this up after EQ....

Use the gain matching technique since both subs are of same model and make

What you can try with this LF knobs on the seatons is to look at the graph, that from 30- 10hz it’s approximately 4-6db post EQ

Here is what it does... this is more to preference after the system is calibrated to reference

It’s a house curve Low frequency boost that uses the built in EQ from seatons

OK. So I got the F18i calibrated. Bass feels more powerful and controlled. It feels very different from the fv15hp. The bass can make a wobbly jelly bass feel from kungfu panda skadoosh scene.

Next thing will be room treatment cause there is quite a big dip for one of the subs. And also the impulse response for the subs after calibration is still very wobbly compared to the speakers graph.

Will post pics of the graphs tonight.
