Took my favourite iteration of the phase plugs and acoustic lens I've been designing - should improve driver accuracy and develop the far-field response better, and reimagined as an intricate galactic design.

Recessed the cable runs, accent panels and text to make either face selection for colouring, (looking at that Palette Pro3!) or painting. Thinking gun metal greys, greens and yellows!

Support material under the phase plug and lens will be needed but otherwise printability on a large machine should be simple enough.

This is a step assembly showing a screw-in extension to the phase plug for proper dust cap matching.

Combining a few ideas I've had over the competition. 

Started with a phase plug on the woofer, added an HF acoustic lens to push the HF more coaxial with the midbass, then imagined them as an engine exhaust and power core!

Support needed behind the lens and on parts of the phase plug underside, the top surface is overhang-free (lens should be tricky, but printable)

Now with phase plug! As, of course I had to add one.

#3DPNSpeakerCover Acoustic Lens V2 Main Cover

Simple Acoustic Lens design, rolls high frequencies over the midrange plane. 

Extended lens element disrupts standing waves across the midrange driver

#3DPNSpeakerCover Full Cover Acoustic Lens

V3 Phase Plug Grill Design:

- Added more angular surfaces to underside of phase plug to disrupt standing waves

- Further increased open area, adding twist to the dispersion channels

- Added more clearance close to cone surround

- Improved printability - max overhang (except mounting points) is now 40deg

Notes - running the driver past it's linear response may interfere with the phase plug - clearance is 8mm, linXmax is 6mm
