Cabinet is width x height x depth = 216mm x 406mm x 260mm

The order of the graphs is always:

1. sketch of the loudspeaker

2. frequency responses of the tweeter without crossover.

3. frequency responses of the tweeter normalized to 15°

If you arrange the tweeter on the baffle so that the top edge is only half as far from the center of the tweeter as the side edges, you get a slight improvement - version v2

The next step could be to bevel the side edges. So we grab the virtual saw and make a few bevels.

Version v4 with 40mm/30° bevel.

This significantly improves our design.

If you immediately hurt yourself with the saw, you can also grab the sandpaper and start sanding curves (for hours and hours...).

Version v5 shows 18mm rounding of side edges.

This optimization is also a significant improvement over Version v1 and v2.

Now we'll get cocky and add a rounding to the top edge as well. We don't even need to think about that, do we?

Version v6 shows 18mm rounding of side edges and top edge.

The result regarding the directivity is mixed, in the range 4-5kHz there is an improvement, but in the range around 3kHz there is worse directivity.

Now it's up to the marketing department to decide what to do next

**UPDATE:**The simulated drivers are the 6.5'' Purifi woofer and the SB Acoustics SB26ADC tweeter.Cabinet is width x height x depth = 216mm x 406mm x 260mm
