You are correct. I did arrange them in my room without "installing" them on the walls. Here is what I posted in my build thread.
Well, I spent a few hours in the HT tonight. I demoed familiar CD's, DVD's, etc. and here is what I have concluded....Acoustic Panels are pure snake oil.
Just kidding. Stick out tongue . My findings were quite the opposite. My methodology was not scientific, I did not actually measure anything, my observation is only what I heard through my non-audiophile ears.Placement:
I ended up placing the panels as I sketched out in the above diagrams with the following exceptions:
I did not place Bass Traps in the top right and left corners (will need to make a shelf for that).
I put 1 Acoustic Panel behind the Projection Screen
I did not place two Panels on the Rear Side Walls
I only placed one Panel on the Back Wall.
Other than that, everything else was placed exactly as I had originally planned.Observations:
When doing the Clap Test, I still hear a slight slap echo (maybe coming from the ceiling or other parts of the wall that do not have panels) but it is not near as loud as prior to adding the panels.
Immedately, I noticed much more clarity in my main speakers and even my rears seemed to sound better. The center was crystal clear as well, dialog was slightly better (I think this can be helped with proper EQ).
I have not re-run EmoQ (which to me is kind of useless) but I will give it a try with the panels installed since I have 3 Presets I can save and I've only used 2 Presets so far.Bluray Observations:
Book of Eli - I watched the scene where they are in the old couple's home and the crew shows up and begins to demolish the house with their weapons. Every bullet was so clear, pieces of wood flying were very distinct. Lots of detail were heard.Music Observations:
I have always heard that room treatments are one of the best investments you can make for audio. It makes logical sense. Just thinking about the first reflection point. Your ears are hearing sound coming straight from the speaker and then a reflected sound slightly after the initial sound. This causes the sound to be muddy or muffled since your brain is confused. With panels at the first reflection point, you hear the sound coming directly from the speaker and it is much clearer.
The Soundstage was more open and wider. I was able to hear every chime, every pluck of the guitar, breaths etc. Again, very distinct and precise.
I'm not sure how much difference the Bass Traps made as I did not do a before/after test and I only have two of them and they are only in one corner of the room. I'm sure it helps but I know the bass had already smoothed out a lot since I added the 2nd subwoofer.
I brought out my SPL meter and cranked a song up to 102db (much louder than I typically listen to) and the music remained sharp, detailed and unstrained. It never got muddy, even at very high volume.My Conclusion:
I've always known my room had acoustic issues. Lots of hard surfaces and plenty of echo that was causing the audio to not be as clear as I believed it should be.
Since they are black, they match perfectly with my color scheme.
They definitely added more clarity to instruments, surround effects.
I met up with my neighbor who lent them to me and told him to think about how much he wanted for them. His reply was that he was just glad they were being used since they were just taking up space in his garage. I got the impression that he might even give them to me but I don't mind paying for them so I told him to let me know how much he wanted for them. We will see. He did say that he bought them cheap and paid $900 for all of them ( the 10 panels and 4 bass traps that I have and the ones he is currently using in his living room (maybe 2 bass traps and 8 panels).
A few weeks ago, I dropped my Nikon D90 camera but it's on it's way back from repair and will be here on Wednesday. I'll work on getting the panels mounted so that I can take updated pics of the room with panels installed when it gets here.
