Plus I also had applied som LinAcoustics around specifically behind Surrounds and back wall. I still don't have any treatment right behind the MLP because that's where the door is. I'll do it later because I'll have to make a poster using acoustically transparent cloth to cover the panel to avoid WAF.
After running 9 points to cover all three seats, I got much better results in terms of FR and also Waterfall. I'll provide link to mdb and dirac at the end of post. Here is the waterfall of C+B. Please note that this is a 300ms and not 450ms. I followed Jerry guide to keep the difference of 40dB from top reading to lower.
Now that we know how the room is acting in terms of bass, let's discuss how well Jerry's curve sounds. If I need to explain it in one word, i'd say WOOOOOWWWWWW. I spent some good time listening to the contents I'm very familiar with. Contents including
1 - Ring my bells song (HD version)
2 - Maze Runner
3 - Transformer 3.
I"ll discuss the difference of bass and then other aspects. I had always been chasing the bass that hits in chest. Read Hard Knee curve article and kept on following it. Therefore, my curve looked like a big steep from 50 to 100. Jerry's curve is much more different from it. After I used his curve, there it is. I got very very clean and heart hitting bass. I won't say that its so heart hitting that it makes your heart beating very fast but I do feet the hit in my heart. To get the full heart hitting impact, I think its important to have one sub NF (near field). Then the game is on. Regardless, bass sounds very very good. I like it very much.
Now the center channel. Oh I just love what Dirac does to center channel. I don't for a second feel like there is a speaker behind the screen. It feels just like someone is talking right in front of me. After closing the room and been able to add some acoustical treatment on back wall and surround area, I can hear much clear sound. Dialogs are so clear that I have absolutely no problem understanding every word. I also don't hear any distortion at all. I was a bit concerned about mid-bass with Jerry curve but after listening, no concerns at all. Very good (or should I say Jerry good) mid bass :-).
Surround Sound. Wooowww. Having closed room and Surround Back speakers and surround all around me made a huge difference. What a big difference having a close room made. Such an amazing engaging experience. I also have 4 ceiling speakers and they are properly aligned (equal distance). All are 4 feet apart from MLP. I get completely surrounded with sound effects.
Finally, even though this is a sound related thread, I'll share some of my experience related to display. I'm still working on room and I plan to have everything covered with Black Velvet in between MLP and Screen. For now, I only have my panels b/w MLP and screen, below screen and above screen covered. All walls are already painted black and therefore most of the room already kinda disappears but after I cover side walls and ceiling and floor covered with Black Velvet, everything will completely disappear besides the screen. So I have 130" 2.40 AT screen combined with JVC RS500 and projector mounted to minimum distance to get good brightness while sitting 10.5' away from screen. The experience is very immersive indeed. Very 3D like experience. Screen center point is only 5-6" higher than the eye level once seated and this gives very good immersive experience and makes you feel like you are almost in it. Hard to explain with words.
If any of you are in NJ, feel free to contact me if you'd like to have a demo. Even though I still need to do a lot of work, I feel confident enough to demo it to others for the first time in my HT journey (around 3 years).
A very special thanks to Jerry for providing the curve adn all other guidance. Markus also helped me out a lot understand and working with bass/speakers around cross-over.
