I have been noticing lack of umph in gunshots and other mid-bass sounds and I followed most of the info on proper setup of MCACC...I also have 2 HSU subs and crossover at 80hz...speakers are all small (which still bothers me but it's the industry standard I guess (roll-eyes)...
If this helps..I will again spill out what I got to see if any help can be given...as in anyones wishes...I want the most umph outta the system...
RF82 (LR) FR-33Hz-23kHz +/- 3db
RC62 (C) FR-57Hz-23kHz +/- 3db
RS42 x's 4 (S) FR-52Hz-23kHz +/- 3db
After trying countless variations with MCACC, I found that I can get a big variation in gunshot sounds, ranging from a penny cracker sound to a sharp crack/explosive sound..using the same scene in a particular movie..
The variation in gunshot sounds (along with other explosive sounds) is achieved by how MCACC is setup..and where the mic. is positioned..
This is what I did for my final set up to get that loud crack/explosion sound from gunshots..
Firstly, the mic was placed on top of a tripod and positioned with the tripod on the centre seat, with the mic. near the back and the mic.was raised about 6" above the back rest..
The MCACC settings I used were
ALL CH ADJUST
THX..Yes (even though my speakers are not THX)
Then all front speakers were calibrated to 75dB. and the surrounds to 78dB. (dipoles)..
With EQ..I reduced the 4K levels by 2dB. for the L&R speakers..and increased the same frequency by the same amount for the surrounds..
I also reduced the standing wave setting for the 103Hz position to 4.5dB...but that may only be for my room acoustics..
It did however produce a better projection of voices..which may have something to do with better gunshot sounds..
The end result gave me explosive gunshot sounds, where you could almost feel the percussion from the guns in the opening scene in Qantum of Solace..
In Indiana Jones "Kingdom of the Crystal Skull"..in the scene where he's being shot at as he runs across rafters in the warehouse, the shots have a distinctive crack to them..
I'm now very happy for the first time with the settings for MCACC with a very dramatic overall sound quality..
I hope that helps your problem..
