Sorry for blurry images , they are from my camera.
After three weeks of listening and tweaking and three iterations this is final and works quiet well. TWFK for highs and mids and ie8 for bass.
It has recessed sound tubes to prevent wax from entering the sound tubes, on face plate there is bass port for IE8. I have used mmcx female plug on shell and right angled male on cable.
They are quite something Muzo! Some amazing efforts coming out of this thread....wish I had more time!!
