Slow work takes time...
But it eventually gets done! sometimes...
This is a test setup with just a 1 cu ft sealed enclosure on the woofer, no attempt to address sub 100Hz yet. Measured in room with a 200ms window; 1/24 octave smoothing- no trying to make things pretty and smooth with 1/3 octave smoothing.
For those that are curious, with and without the notch filter, showing distortion products. With this tweeter, you could likely leave it off without issues...
With ultrasonic notch filter
Polar response, 0 - 30 degrees, 10 degree increments- this would constitute the typical direct sound listening axis.
Polar response, 0 - 70 degrees, this is the forward 140 degree arc. These sound very good walking off to the side compared with most speakers.
