Give Oskar a Wedgie and Heil Smooth Out and Won't Be Such a Dip!

Test video. Heil is fed pink noise from the Behringer through a 13.3 mfd cap and in series with a 4-ohm Mills 12.5 watt resistor. This creates a high pass Butterworth filter at ~1,500 Hz.
Next step is to make a 30 degree from acrylic rod. The wider wedges didn't seem to work as well as the smaller, but I only tried a couple at this point.




Mic is on-axis at 2 meters.

Edit, I guess they don't make acrylic rod in that angle. I guess I could try to bend some metal, but it won't have the same finesse.

Because I can't find what I want. I've designed my own wedges from acrylic plates that will be stacked to give the desired height. I have black, smoked, and clear acrylic and will do some form of pattern up the wedge.


The pieces will be bolted together as the Heil is. A screw will come from the top and pass through the wedges:

The bottom wedge will be cut to hold a 8/32" machine nut so that the ~27-32 pieces can be bolted together. These are actually 40.6 degrees to leave enough meat to fit the nut and keep the overall length to about 1.2". Longer pieces showed less effect.



The screw/stack will proceed further through the upper base that is slotted to allow the wedge to be adjusted. Note the cutout for the "Heil glue" so it can snug up to the Heil base.

This is glued to a lower base that will allow for a nut to be tightened with a small pliers.



I've also designed an "assembly bed" that has the same angle as the wedges that will hold them to assist in putting the pieces together and deciding on a color scheme. The bed is marked for the correct length making this much simpler.

Made these today. Tomorrow will cut ~70-80 wedgies with a round hole.

Done. Now for some listening.
