Height Reflective Speaker inserts for Atmos / DTS

thingiverse

Want some more immersive sound from your speakers? Want to keep height speakers invisible for better WAF? This is a little project to insert a car-type coax driver with an angle towards the ceiling into tower-speakers. I chose a pair of Axton ATX-100 drivers, which come with a deeper conical design for less dispersive, directional sound. The diameter of the driver's opening is 93 mm and the screw pattern is a 84 mm square for those. Cut-out is about 182 mm x 132 mm. (Yeah, you wanna destroy your lovely speakers.) This won't work out for most speaker designs, but my have an encapsulated mid-range section. The insert is held in place with twelve 2.5 x 16 mm screws for wood. Consider 1.5 mm pilot bores. Driver plate is seperated from frame for better printing and material choice. The assembly needs six M3x6 screws. I used flexible adhesive to permanently seal the bond. Also some 10 mm foam pieces were glued in place around the driver to attenuate side-reflection. I routed the wires down to the original (and useless) bi-amping terminals. My AVR is driving the height speakers best with Neural:X upmixing or Atmos sources. Does this all make any sense? Probably not. But it looks interesting.
