Miniwaves foam mod


My Miniwaves are a budget test of the waveguide approach to speakers, including a 6" Vifa midrange and B&C compression driver loaded into an oblate spheroid waveguide. Previously I tried a foam mod with dacron, with little success.

More about the Miniwaves
In a recent waveguide shootout, they had the least amount of horn harshness.

I've found that reticulated foam takes waveguides to another level, hence this mod shown here.

First I created a template. I then cut the foam using the soldering iron. The result is shown below.

You can see I've tried cutting the foam differently on the outside.
