I  find the JH13's tuning to generally follow the Olive-Welti reference curve.

 

Hmmm.... I'm too skint to buy a CIEM at the moment, but previously owned UM's Miracle, and I really liked it overall, but found that the bass was fabulous at times, and rather 'elusive' at others (incidentally, it was being driven properly, by a DX100).

 

I dislike bass-ramped, and generally favour as close-to-neutral response as possible, but a subtly & smoothly boosted sub-bass (not mid-bass!) might suit me quite well.

 

I have heard that, broadly-speaking, the Miracle is 'similar' to the JH13 FP, so it remains on my list of (eventual) potential replacements for the Miracles I was forced to sell.

 

This Roxanne looks rather appealing, too.    Sorry, very appealing, but if it's a ludicrous bass monster approaching the JH16, then I won't be even the slightest bit interested :wink_face:

No I do not believe it to be the bass monster, if you do not want it to be. From the video you can have the settings way down or gradually boost to your liking. I think this is a great idea as many songs vary in quality & quantity of bass, also some genres would welcome the extra bass.

The great thing is that Jude mentioned that the bass did not effect the other frequencies...... $1599 USD is a lot of cash, ill wait for the reviews first.

But definitely excited...

Bigger soundstage than the JH-13?, more detail? What's the extra hundreds get you?

carbon fiber :p

JHAudio is all about the numbers of Driver and Carbon Fiber

 

FitEar is all about the Tuning, Acrylic and Titanium

 

You choose :)

And you know this from owning se215s and hippo.

:confused_face_2: There some very good technical reasons for vibration cancelling Siamesed drivers so 3 becomes 6 with lower harmonic and intermodulation distortion with no vibration and better dynamic contrast by each working less hard. I guess you aren't aware of the well respected JH5 2 driver unit that's been around forever. Doesn't mean you can't like Fitear better but that was very silly.

How'd you come to that conclusion?

 

I have the JH13 Pro (pre-Frephase and Freqphase), the Roxanne prototype, and the FitEar MH334 (custom), and I couldn't disagree more with your post.

Anti-Hype Force Field Engaged --- There are a few questions that need to be answered before we declare Roxanne the Siren of Sirens:

  1. First, the bass adjustment knob thingy is essentially a potentiometer. How much noise/IMD/THD does that thing introduce to the sound?
  2. Second, if it's a three groups of four drivers, then it's essentially a doubled-up JH13 FP. I'm not saying that quadruplet drivers aren't of benefit (twin motors do indeed significantly reduce vibration, in turn allow for lower distortion), but are they really quadruplet drivers? Or are they two dual drivers attached together in a single group, like the JH16's bass drivers? Also, if it's still a three way system with what I imagine to also be a triple bore outlet, then FreqPhase as an implementation is essentially unchanged.
  3. Third, how much more will the new proprietary plug force the faceplate to extend from the sagittal plane (essentially at the mid-clavicular line) --- perhaps that will actually help in enabling JHA to stuff all those drivers in?
  4. Last, is that a true carbon fiber layup, or is it a thinly-cured UV shell with a single layer of CF under-wrapped to give the guise of a CF shell? There are lots of different carbon fiber types in different tensile strengths and moduli of elasticity, as well as different patterns of weaves for individual sheets. Different layup techniques require different types of resin and curing. If it is a true CF shell, then how can we ensure that the resin material is hypoallergenic?

I anticipate the latter...

Same thought crossed my mind, especially since I know how much of a challenge it is for Grzegorz to squeeze 5 single BAs into the SE-5. Yes, I know different BAs have different dimensions, but still... 12 drivers, even if they're small ones or dual-packaged, is still an awful lot of BA real estate to be packing into a CIEM shell. I foresee that those of us with smaller ears may actually be turned away, owing to there being insufficient space in the shells, a scenario that does occasionally happen to would-be SE-5 customers (although I sense that Grzegorz is becoming increasingly skilled at his art, and succeeding now where once he might have declined).

I imagined the same as you, Tom - thinly-cured UV acrylic shell, and then carbon added in afterwards.

 

Since it is not under a great deal of stress, I wouldn't be all that shocked if the carbon is whetted with UV acrylic, rather than amine / epoxy / polyester resins. As you know, it's quite an accomplishment to tidily apply carbon (especially such coarse weave) to such a small, awkward shape (and especially without resin bubbles), and I shall be mulling this over, as I have some alternative ideas as to possible methods, which haven't totally coalesced in my mind yet. Although I wouldn't personally want carbon CIEMs (I prefer transparent shells as they're less obvious in the ear), I take my hat off to Jerry for achieving this result with genuine carbon fibre.

Ummm...woah.

 

Anyone want to buy my 16's?

That is my biggest fear, and it has also crossed my mind.

The driver count seems high to me as well but sometimes running different things in parallel can give you a flatter additive response. Trick is to keep it timed up which JH has been all about lately. I guess we'll have to wait and see. My guess on the bass control is that there are 4 (or more) bass drivers and that the pot only controls 2 of them for contributing to a below 100hz rising effect. In that case, the pot isn't handling all the signal level so would be less critical. Just a guess.

I'm not going to buy these(too much money for me), but I'm truly impressed with these. They look super nice, great job, JH Audio!

Credit to Jerry Harvey though, you have to give it to the guy....Always giving those breakthroughs in tech,

Everyone else simply follows......Then giving their slant on it.:cool:
