Faulty designs tear down is as interesting as TOTL teardown. The graph shows that the 10 mm is slightly underdampened, a naive attempt to low pass it.

[@hi-friaudioman]

It could be a cause of under-dampening in the rear of the DD but I'm thinking it has more to do with the poor acoustic design of the forward cavity and the interaction between the 10mm and the 6mm. You see how the graph gets sucked down around 800kz before regaining energy? A classic symptom of poor frequency divider implementation and phase cancellation between drivers. However I still think this iem's biggest sin is spec-ing a good 10mm DD but the cheapest, crappiest 6mm for the highs. 🤦

@@hi-friaudioman Interesting....I was thinking of underdampening because I always get this upward convex curve when underdampening. This setup of 10 mm + 6 mm is a potential way for failure because I don't think there is any Mids/HF dedicated 6 mm. Even the Penon serial is said not being for treble heads.....
