I have cut a piece of 4 inch thick foam to the size of the inside of the cabinet.
It makes a subtle difference with just the foam, but there is still a worsening of the fidelity when the back is placed over it.
Even with a 2 inch slot at the top it still sounds flat and uninteresting.
I will wait till my son returns home from work, his musically trained ears are better at mine at distinguishing what is wrong and missing with audio.
But I reckon that an open back is the way to go with this 10 inch driver.
The problem is probably something to do with the large thin paper diaphragm and it not coping well with the added air resistance caused by closing the back.
