Recommended printing settings:

PLA is okay; PETG is better.
At least 6 perimeters / walls / loops all the way around.
At least 20% gyroid infill.  (40% recommended.)

Disclaimer:  This is an acoustic model.  As such, it does not scale, nor is it compatible with drivers other than the ones specified.  Scaling / incorrect driver(s) will result in significantly diminished performance.

Assembly notes:  (See video.)

Note:  If you plan to use the two halves of the soundbar separately as a pair of stereo speakers, be sure to seal the unpopulated screw holes.

Wiring / DSP / amplification:

The Piston Block is an isobaric speaker.  Each enclosure requires four pairs of the Dayton Audio DMA70-8 drivers; 16 in total.  Use the following series-parallel arrangement:

Power handling is rated at 100W per channel.

If DSP is available, apply a 55Hz high pass filter to protect the drivers, and a broad Q -6dB peak filter around 600Hz to dial down the midrange.
