I finalized the design work on these today. The attention to detail in the wave guide design really paid off. And the network turned out very simple.
Here is the crossover response showing each driver and the sum.
And just the on axis response.
And since these could be mounted high above a console, here is the response on tweeter axis and on woofer axis. It is pretty flat both ways.
And the spectral decay is about as clean as any speaker I've ever measured. These driver settle super fast and clean.
Pretty even horizontal off axis responses too.
And the vertical off axis is very consistent too. For playback in a listening room they might like a slight tilt.
And they have an easy to drive impedance load.
Now time to finish assembly on the first two pairs.
