Our pet demon poked both tweeters and so gained her first lesson in resonance modes of acoustic emitters.  There were very subtle differences in response curve of the tweeters dented and in “fixed” condition.

Usual method of fixing them was implemented.  To pull the tweeter dome back out, made a gasket from blue tack and pulled a vacuum in front of it.  Obviously this means sucking on a tube...

The demon might not jab tweeter cones again for fear of another impromptu science lecture.

In other news, mini-DSP implemented for flatter response and smoother bass roll off.
