So I've been reading about how this speaker is more dynamic than that and it go me to wondering how much dynamic range there is in a typical action movie. Has anyone measured it, or is there a source to reference this info?
8/12 edit: I've been speaking with MKTheater behind the scenes about dynamic speakers, and I asked him for a good movie scene to test the "oh crap" capability of my own speakers.
He recommended chapter 20 of Batman: Dark Knight on BluRay, in particular, the section of the chapter where a semi truck slams into an armored police van (about 1:16 into the movie).
To test my set-up, I needed a reference point first. At the start of chapter 20, one of the guys in the armored police van says "we'll be like turkeys on Thanksgiving" when they are diverted to lower 5th ave (the 1:15 mark). I measured roughly 76dB on my SPL meter when he says that phrase. Leaving the volume at that setting, when the semi-truck hits the armored van and pushes it into the water (just before the 1:16 mark), I measured a 99dB peak for a diff of 23dB. SPL meter set to C weight and Fast Response.
I also disconnected my sub and replayed the semi-truck slam scene and still hit 97dB, for diff of 21dB. Crossover set to 70Hz. Is the 21dB difference I measured the full range between the dialog and the car crash, or are my speakers compressing the sound?
Anyone have a way to take a feed off of a Blu-Ray player or a prepro to measure the actual difference between the dialog and the crash on the recording?
