а почему пердёж такой на перегрузе?

In our experience, we found cabs with peaks at various frequencies, not just 75 and 100 Hz.

Some cabinets have two peaks, and we even found one cab with a settable impedance that had two peaks when set at 4 and 16 ohms and three peaks when set at 8 ohms.

So, largely speaking, what we found was a variety of curves. We also studied their influence on the sound, which was sometimes major, sometimes measurable but almost inaudible.

As always when designing a product, we tried to focus to the most important aspects of all this, and not get lost in less significant details. In the end, we designed a curve that matched most of the curves we got, that was efficient to build, and mostly, that sounded good ! In our opinion, we succeeded, but don't trust me : go try one and hear for yourself

Серая кривая - импедансная "голого" динамика, ничего необычного. И с акустическим оформлением у KMG всё хорошо, раз коробок резонирует внизу чётко там, где и подвес динамика. Часто импедансная кривая кабинета действительно имеет два "горба" по НЧ, - акустический резонанс будки и "механический" "нижний" резонанс динамика.

Но в случае моего каба, резонанс на НЧ все равно один.

То есть, наличие дополнительных НЧ резонансов - это свойство конкретного каба с конкретными динами.
