Audiocase S10 vs Teufel Rockster Air 2 (Patreon)

This will be my final uncut video for the Audiocase S10, I had to edit the labels because it said S5 by mistake and cut the last track for the public version due to copyright reasons. Unfortunately I was not aware how loud these speakers are and didn't notice my voice became hardly hearable when I was talking. 

I had done some measurements in the meantime, which show that the Audiocase S10 has a pretty balanced response without any obvious issues, except some stronger lower mids emphasis (black default, green outdoor EQ):

The Teufel on the other hand has this weird one-note bass peak which probably is the reason for the knocking sound, I also included measurements with the bass and treble toned up and toned down, you can see that the control range is pretty high:

Although the peak gets reduced at high levvels, it's basic tuning is probably to blame for the boomy undefined sound.

With both speakers side by side the differences become even more obvious:

Both speakers reach down to 40hz at 0dB, just that the S10 has slightly slower bass roll off and even more treble extension, but these measurements were all done exactly on axis and do not show the treble loss off-axis, which is simply way too strong. Together with the distortion at levels above half it makes the speaker unusable IMO, but maybe this particular unit is defective. I wonder about the response form Audiocase once they watch my video.

What are your thoughts?
