Following on from here:
Does anyone have a zoomed impedance response (or log scale) between 500-2KHz
Does anyone know if the rear cup can be removed?
Hats off to @silverD for his waveguide. Now I have a suspicion (but no evidence yet) that the midrange amplitude response and harmonic distortion could be further improved with a modified rear cup.
Cursory look indicates the rear cup is glued.
This is the 7600, but it is the same driver it just has a more of a waveguide faceplate.
A bit of hot air gun later…
do tell!
I’m happy to share the waveguide STL, but I’m in no way an expert. I have yet to make progress on the build with the DM-7500.
If I am not mistaken I think Thanh is trying to get one of us to heat gun our DM7500’s to remove the cup - too cold here and don’t have a heat gun . . .
To be clear, I’m not trying to talk anyone else into doing it. I’m trying to talk myself out of the being the first idiot to try it. I’ll only even consider it once mine arrives and I can inspect the glue line properly.
I found a pair for a reasonable price from a trusted distributor…
