    So, what did you learn or do you have a suitable build? I don't have the time for 50 iterations!

    I use bondic to adhere my components to the shell.. Regarding the sound, yes MOST of your sound will be from the end of the earpiece but any loss of seal due to bad fit (if you can hear clear outside noises with your IEM's in place) will result in a LOSS of low frequency...again your bass will...

    I think others may have alluded to this, but it is 95% of the time a adhesive problem. If it sounds great, then once you start wearing it, you loose bass over time it is down to several culprits and they are adhesive based. 1) Make sure you use good adhesive on the BA to tube connection. I...

    I use the brand from lightning enterprises....doesn't shrink, very tough, and doesn't turn dirty brown with re-use.

    Make sure you release...depending on how many shells I'm making, I will put my colloid back into the plastic form before pouring resin, as i don't want to rip my colloid pulling multiple shells out. Last, wax does make a difference...I use the rite dent as it is very flexible and doesn't flake...

    Home-Made IEMs

    I bough the UV light strip off of ebay and my basic finish setup is a nail lamp like yours...I honestly can't remember the Nm wavelength. I did drill a hole in the bottom of the nail setup...the little slide out tray, and put a mirror on a platform attached to a motor. It spins the...

    The SUV s The shell will release from the mold without any releasing agents. Be careful and take your time so as not to rip your form. There is a tacky/greasy layer called the "inhibition" layer that forms on the surface of the shell due to the presence of oxygen. Simply place your shell in a...

    Thanks! That was the graphs I remember seeing and I thought the analysis was solid. I went with the 1mm diameter as it was readily available and I recall you hinting at decreased marginal returns on tubes smaller than 1MM....i.e. didn't really add much to the game below 1MM. Was i wrong in...

    What low pass values do you use for your filter?

    Home-Made IEMs

    Any you are correct! 38 is a much more powerful sub woofer. It's SPL is much higer than the CI, which is great in original design. But this was a retrofit, which made me think about how to play with the original configuration without destroying what I had already built. You mentioned crossing...

    The original poster if I recall was in Oklahoma City...the only thing worse than my building skills is my computer skills and memory! Anyways, complteley agree with damper placement, length, etc. Dhruv had suggested a few builds to me using a 1mm tube with long lengths just as a sub...nothing...

    When I say no flub, it means it is very fast, transients are very accurate, and there isn't any distortion caused by varying playing styles even when you hit the lowest notes. Some speakers sound great and fast when you're playing higher in the register, but "flub...crap out...become mush" when...

    Home-Made IEMs

    Yes! I did a few builds (MASM, MASM Pro) and no matter what, I wasn't feeling the bass. Someone (mattmatt possibly....i'll find and give credit) did a study of bass drivers with varying tube diameters and types. It got me thinking of the best configuration for an add-on sub for just these...
