Maybe this thread is not the right one for a contraversial or discussion of the LF of the System 16 but I would like to give a few practical facts.(maybe a Moderator could put the OT postings in a new thread?).

A part from the fact that technical specs for this system are nearly impossible to get since Nestorovic himself gave them rarely out and the last ones were given over 10 years ago; clarity, intensity, precision and quickness of the LF are in this system simply amazing.  I never had apparently acoustical problems with this system in the different rooms I installed it, when using the settings given by Nestorovic. ..or maybe I wasn't aware of them? Problems arised mainly when I started to do acoustic treatments half the way and trying to play around with different kinds of positions inclusive other heights.

But back to the facts concerning specs: since the publication of the last specs, Nestorovic has upgraded his system three time using different materials for the inlining of the speakers, type of electronics, patterns to help the diffusion of the sound, and new tweeters.

All these changes didn't come in the "official" specs. Also there are very very few of these systems around (since year 2000  not more than 10) to be able to analyze it and see exactly what is inside and how it was made. Even if I believe Nestorovic didn't change the way the two 12" work together, he did changes (cone material?), which gave much more LF clarity in comparison to the versions before year 1999. I don't really know how much "directionality" Thorsten wants /needs, I can only say that even in the most complexed orchestral works, you can definitely hear exactly were for example the bass drum is positioned. I don't know if that concerns his interpretation of LF directionality. It is very nice to look into specs but it would be even better to see yourself if the reality is according to the theory and if the owner of a system is not just positively exagerating.
