Just my 0.02 € :
Having an electric sub doesn't imply its going to stay "quiet" across the entire speed spectrum. And if I remember correctly sound levels in subs don't increase linearly but by discrete thresholds. So its conceivable that at high speeds and Kilo actually produces more noise than the Akula II. You have to take into also into account that the Kilo is an "old design". How about the sound levels of modern AIP subs, Collins, Type 212 IT/DE with respect to Akula II ? That should give us a better picture of the situation.
Loblo : how much noisier is the Kilo at max speed with respect to the Akula II at max speed ? It would be interesting to compare also to the noise level of the 688 at max speed.
