Yet another update (sorry Umapati for hijacking your thread
):
I played the same scene from Avengers movie using a recording of the movie from star movies hd, and it appears I hear the same 'Phattt' sound, so it seems that it was not a problem with the source material. I felt lost after that! Cheated
! However, then lightning struck and I seem to have removed the 'Phattt' sound problem for good :yahoo:...and that too by fluke. Now I can play the same scene again and again at 85db (+5db over the reference volume of 0db), at crossovers of 100Hz, and still not get that same sound. On top of that, the system sounds much more louder as well even at lower volumes.
All I did was run Audyssey again, but this time with a proper tripod and measuring all the 8 positions. Previously I had just measured the 3 main seating positions, but after reading more about audyssey, I realized that all the 8 positions are important (irrespective of whether anyone actually sits there or not) as based on them the system understands your room dynamics. I have to say.....I could hear a 'marked' difference in the sound produced by the speakers now. I was actually surprised, as I thought that the system sounded great even before, and frankly I was not expecting much audible improvement in the sound, but boy oh boy....was I in for a treat!!!! The system sounded so much better that both my wife and mom-in-law, who had heard the system before, were awed and said that it now sounded like a totally different system
!
Now when I listen to the same scene with audyssey turned on along with the 'Movie' dynamic EQ, there is not even an iota of that phatt sound. However, if I do play the same scene using 'Direct' sound setting (i.e. the Dynamic EQ filters which were calculated based on your room are disabled) then I do hear the phatt sound, which tells me that audyssey actually removed that problem by creating a dynamic EQ based on my room.
During the time I was researching the HT products, I really used to feel that audyssey is not really that great and its more of a hit or miss kind of thing (based on some stuff I read on the internet), but was I wrong or what!! Audyssey is pure magic! The difference that it makes is audible even to the most untrained ears. I think my room (8ft viewing distance wall to wall, right side opening to the other half of the living room which further opens up to the dining room...all without any doors, left side a full glass door, coffee table between the tv and couch, left speakers almost touching the side walls) would have been a challenge to calibrate even for the most trained sound professional, however with the changes made by audyssey, the system sounds much better than what I demoed (I had demoed moviestar 70+) in a properly calibrated demo room!!! Even the music sounds 10 times better (it really sounds AWESOME now) with the new settings. I am even more impressed by this product!
PS: I tried setting the sub right next to my couch (4 inch gap between the couch and sub as well as between the sub and side wall), changed the phase to 180.................all I can say is if anyone has not tried this position for a sub yet.....do so now....its worth dying for
!!!! (
Warning: only for movies though.....stereo music sounds wierd with this)
It seems all my problems have been solved now, and the system sounds much better than ever
!!! So, no more updates from me......unless ofcourse I discover something magical again
), and I swear, every Gun Shot we heard, Every Explosion we heard, we felt its impact
