    Yeah well, we always want more don’t we :wink: ?

    Fibae Black vs Fibae 3?
    Not really shure which one to order... :)
    Coming from (old) Shure SE530, and prefering mids and higs to lows.
    Inclined towards Fibae 3 though.

    I'm going to have to listen to the Comet again. Clarity & staging are very important to me. I'm also a treble-head.

    Only a couple of days left of december for the pre-order guys! Going to put mine in tomorrow. No I still haven't decided. Everytime I think "that's it" a small voice in the back of my head goes "yeah, but hang on what about..." :) :frowning2:
  5. davidcotton
    Sounds like Fibae 3 would be more your cup of tea. Tried pming Piotrus for his advice? He actuallly said I was better off sticking with the fibae2 for rock and metal than the ei3 which I had been considering as it was on sale.
  6. Deezel177
    You’d probably enjoy the Comet more, then. Keep in mind though, its bass is noteworthily lean.

    Yes, I remember thinking that. Unexpected coming from a Campfire Audio IEM. I may be a treblehead, but I do appreciate sub-bass. May need to wait until more info is available on Fibae 4. Back to the FIBAE thread I go.

    I may go for universal Fibae Black to complement Harmony 8.2. I have to give another nod to Piotr for offering the custom for the same price; this does make it so tempting to go for CIEM though. :confounded:

    Honestly, we are not trying to hide anything. You can order Blacks with clear faceplate and see all the insides - we even have a pictures showing the pressure optimizing tube on our Facebook as the main photo. The Black material has been chosen for 3D printing manufacturing convenience - nothing more, well maybe because black solid does look sexy after all :)
    The tube is long indeed but it's manageable length and its length and diameters have been calculated and measured to act on certain frequencies. I'm not able to provide you specification of the pressure optimizing tube - it's our proprietary information.

    I would rather say FIBAE Black. I think there's a lot of parallels to SE530 (which I have)

    Also to address some questions I saw.
    The first batch will ship in January - that's for sure, we are looking at second part of Jan rather than first, but it should start shipping in Jan nonetheless.
    Still we are getting flooded with order - like seriously flooded, so if you place your order just now please indeed expect your IEMs to come rather in Feb than Jan.
    Once we are back from Holidays we will be at highest gear with assembly :D

    Happy New Years everybody and thank you for your constant support! All best in 2019

    well you already did on the first post and i was able to understand after reading this

    amazing work

    It was Helmholtz resonator with damper in it

    You know, you also got something in plus with it

    more volume inside tube, which can reduce direct pneumatic pressure

    amazing work bro

    Thanks. Pneumatic pressure is changed which manifests in dramatic improvements in headroom and soundstage. Still it's very different from other available pneumatic relief solutions on the market because 1) ours is self-contained - doesn't vent to the outside 2) it's not the primary function of the tube, but rather nice addition to it's primary task of shaping fr response.

    λ=V/f (λ: wavelength of sound wave, V: sound velocity, f: frequency), If i want to dampen the 6kHz area where the sound velocity is 340 m/s. λ=340/6000=0.0566 m=5.66 cm. Therefore, half wavelength is 2.84 cm (approx. 28 mm).

    If the length of the bypass tube is set to approximately 28 mm, the sound propagating straight-forward and the bypassing one will have opposite phases and be cancelled out each other at around 6 kHz.

    Hmm. I think it is easier than Helmholtz resonator and is point accurate in either killing peak or adding peak

    After that, adding a multistage damped Helmholtz resonator on spout of BA connected to Back port in phase cancelling point to kill low freq resonance and increase low note reach. For this i wont be disclosing the papers, this is my patent and proprietary stuff.

    I can tell you the above one bro in detail though

    Driver is Vented RAB.

    This is what i was working on

    Since EarCanal is 28 to 32mm, resonance in eardrum rises only between 6khz to 7khz, so this area is important which i can see from your FIBAE BLACK. If i remove the bass boost you did, you did with BLACK, and compare just FIBAE 1 and BLACK....

    IT is plain 100x times better in physical movement of sound pressure. the bass boost is icing on cake.

    even though i haven't heard it, i saw the full internal pic on insta and i was able to understand the working.

    Taking conventional method and perfecting it is the first step to success. well there is some one who is doing this stuff instead of introducing new esoteric tech like others. everywhere i see this blah, this coating, that stuff, but nobody works on the exact sound and its working.

    so respect for that, and respect for your work

    Second step is to master a simple thing to its complex level

    third step is to make it simple again in implementation

    all these steps are easy to speak but hard to do

    Well Done

    But now rises a question

    is it comparable or better than the Holy grail of single driver, the Warbler audio Prelude which uses Sonion drive, which i own

    @Deezel177 posted comparison some pages back.

    I feel that With right tips and good seal it does improve mid bass. But still is lean on sub bass.
    For me spinfit was able to bring out the maximum amount of bass, still personally I would like more. :)

    Pre-order ends today. I set an alarm to remind myself as I mull it over. Down to the last minute!
