>Firstly regarding custom fit versus universal fit issue. The picture below shows the customs with the TWFK located right at the tip of the IEM. This is our unique design that allows tuning without the hassle of sound tubing which will be required in the custom fit version to some degree
I actually asked about your customs not universal, but to clarify, you will use tubes and retune each custom depending on space volume and shape, or you will use tubes and errr do nothing about the varying cavity size D ?
I am sorry I missed that one entirely!
We would do what is necessary in tuning the cavity to maintain the sound signature, but by adding sound tubes from our experience, the sound will not be as balanced/ coherent sounding as universal fit. I hope that answers your question.
