Hello Brandon. Could you indicate the latest version of the CNC file 4 inch for SB26 in millimeters without PS?

I'm travelling for work, so I can't get to that now. I would think any software that works with .stl's should be able to change the units though.

You can open it in for example CloudCompare, and then multiple all the dimensions by 25,4. This would give you everything in milimeters.

What version of the SB21 or SB26 work best?

Many thanks for this wonderful work !


I did not found how to mount the waveguide on the tweeter?

Is it supposed to be glued after removing the faceplate ?
Or is there a stl file somewhere with a standard adapter piece ?

All the SB21 results are with the SB21SDC-C000-4. The SB26ADC and SB26CDC behave similarly, the fabric dome has it's own behavior that is not as smooth as the metal domes.

All the prints have two screw holes 4" apart. I printed a little bar to clamp them, but you could use wood just easily. Also used some foam rubber between the clamp and tweeter.

Did anyone else "find" these cracks when they "sliced" up the SB Acoustics SB21 5" waveguide for printing?

bits in yellow and then circled in red?

Thank you,
