I have built the officially recommended back loaded horn enclosure for my Fostex FE166E drivers. I have placed sound aborbants and sand into it to tune the sound. I found that the sound changes a lot upon changing the amount of materials placed in it but I don't think it is the right sound this driver should produce.
The mid-high frequencies disperse and become muddy when the enclosure is empty. When there is sound absorbant just behide the driver, mid-high dispersion problem is improved a lot. However, the overall sound is still not clear.
I started filling sand to where the official datasheet told me(the canal below the driver). It seems to be optimum when the sand is of a certain volume but the sound is still slow, especially the bass.
Is it the "right" sound from a BLHed FE166E? Is there any better tuning recommeded?
