I just watched ROTF. I like this movie. The soundtrack, though the LFE is largely above 20Hz, overall is superb, IMHO. The surround effects and the crafting of the effects is unique to the Transformers franchise and the visual effects are as good as it gets.
I ran spectrograph while I watched and printed the results from some of the LFE-heavy scenes. I use a reference ACOPacific mic, mic preamp and mic power supply, through an Edirol UA1000 interface, flat to 2Hz, with a subwoofer system that's flat in-room to 4Hz. These graphs were made with a microphone at the LP. The 1st posted pic has the color scale on it for reference. The system is not yet tweaked flat, but is +/-5dB from 4-250Hz, so, as there will be some deviations from the digital graph, it's pretty close:
Anything pink to whitish pink was at -5dBFS = LOUD.
First, the opening Dreamworks & Paramount logos:
Next, the Transformer logo:
Next, opening scene where the big Decepticon stomps the ancients:
Next, the Big Wheel Decepticon transforms:
More Big Wheels:
Decepticons land on and sink the aircraft carrier:
The Mac Daddy Decepticon assembles:
The Rail Gun wastes Mac Daddy on top of the pyramid:
Optimus gets revived, the big dude materializes and skewers him (this effect was the most fun on my system, with a great mix of low stuff and higher stuff):
That's it for now. I'll definitely be watching this one again... and again, and again.
I forgot to capture the battle in the forest where Optimus is killed. I'll probably post those when I get them made.
