    Any advice on shifting the pinna gain peak on RAB-32257 from 4k down to 3kHz?

    Thank goodness, my coupler isn't broken. Sound card fixed it right up. Measurements are a bit wonky, ear gain seems to have shifted up 1kHz? But otherwise it seems to be fine. Anyways here's my first functional 3-way crossover, 2DD+1BA with no physical damping, only electric crossover: And with...

    Right now I'm connecting it to my desktops internal sound card. Tried using a dongle connector but windows doesn't seem to want to recognize it as a microphone.

    Heres the collar taken apart: And this is what I tried in order to get a seal, with no result: At this point it must be a broken coupler, right?

    I'll get a picture when I get home but yeah, it's the stock coupler from sounds good store. I'm not working with customs though, I'll be working with my own stuff shortly but the graphs posted are an off the shelf truthear zero.

    I'm fairly certain it's the coupler itself, the issue is consistent regardless of what earphone is used. I don't think I'm using a conical extension? It's the cylinder that came with the coupler itself. Maybe I should try ordering a new canal extension though.

    Having trouble with my 711 clone coupler and looking for some advice. Huge leak below 3k makes it unusable:The problem is non-variable regardless of tips, iems measured, dac or cable. This was not a problem just 6 days ago, pictured here with same input and output devices and settings, measured...

    Has anyone measured these black dragon earbuds? I'd really like to know to what degree they actually match up to the susvara

    Ooo I don't know how to check any of those things, but you might be right on that front. The larger DD and BA seem fine, but the smaller DD only producing sound(and very quiet sound) below 6kHz might suggest the driver itself is damaged or improperly soldered. Will have to do tests with a fresh...

    Yeah I don't think it's the seal. I got a consistent result from 2 different tips as well as by sealing the entire coupler with putty. Those graphs from my first post are what happens when there's a leak, while proper sealing allows it to get *some* sound below 500Hz. I am trying to read...

    Home-Made IEMs

    Alrighty, I've gotten the response out of "something here is clearly broken" territory and into "gold star for effort": I thought the lack of bass was from the bass driver not having a properly vented back cavity, but I saw someone on here say that wider tubing can filter out low end, and all of...

    Anyone know what would cause bass leakage after front vent has been covered, and coupler is sealed?(first pic compares against Truthear Zero Red measured with same tips to show that there is a seal, second pic shows just the bass DD, comparison with front vent covered/uncovered.)

    Figure I should post what I've done so far here too. End goal is a 1BA mids with 2DD for subbass and treble, but so far I've invested a lot more time into ergonomics and design. Having a lot of fun with it
