Hui music, film sound Pooh

For music in rooms up to 25 square meters, I can recommend the sub. Crunchy precise bass ... I liked very well.
For 5.1 / 7.1 Filmsound the sub is constantly advised to its limits with me, and that with only 50% at the rear volume control of the Sub!
Again and again rumbled the box only uncontrolled or rum began to "flutter" For example, when was an explosion in the film. That sounded then but to very poor.
I then runtergeregelt the LFE level to my amplifier. Then anything Bass While the rumble was heard in the explosions, away, but just to hear any bass accompaniment more in the rest of the film.
Therefore, the tycoon returns.
I'm trying it now with the Canton AS85.2 SC and Mivoc hype 10G2. Both meet soon to test.
At Canton I could imagine that it is nothing to the movie soundtrack as it was reported, is to strike the membrane of the protective grid when the power is too high, so in movie explosions and so ...
Well, you can only test. Sound is indeed perceived differently by each and is therefore subjective, but this rumble did not work ...
