Knowles acoustics just launched a new dual driver, the GM-34020. Is it worth looking into? Lets have a look. I got a pair in just... -

Farquarl replied to the thread Home-Made IEMs.Well it does effect phase, it just doesn´t effect it very much. Imagine a sine wave at 150Hz. You want to avoid that the peak of one...

Farquarl replied to the thread Home-Made IEMs.The Wavelength of 150Hz for example is 228cm don´t worry about tube length ;)

Farquarl replied to the thread Home-Made IEMs.Not quite sure what you mean by tight? a high value damper acts as a lowpassfilter and a lowpassed filter wont exactly sound crystal clear.

Farquarl replied to the thread Home-Made IEMs.Take the highest.
-
Farquarl replied to the thread Home-Made IEMs.Are you sure this is totally sealed? A simple high pass shouldn't be this steep.
-
Farquarl replied to the thread Home-Made IEMs.This looks like a low pass filtered driver for me. Compare the unfiltered curve with the lowpass to the unfiltered curve of the normal...

Farquarl replied to the thread Home-Made IEMs.Now built this in with a normal zobel configuration and compare the output. Only if there is less output in dB this can be considered...
