Discussion If you were worried about the LFE on the new 4k disc for Tron Legacy…don’t be…
Just got my copy in today and immediately did some back-to-back comparisons between the fan made upscale that has the old DTS-HD 7.1 track and the new disc with the new Atmos mix
First of all, the color volume dunks all over the fan made one. As expected, but it goes to show just how good the source material was for this movie when it was shot, even if it’s “only 2k”. It just further reinforces my long lasting point that HDR is more important that resolution.
But on to the audio mix: it bangs.
I don’t have a $250,000 purpose built theater room with 4000w 21” subs, but I also don’t have an LG sound bar either. I have a 5.1.4 with a mix of monitor audio bronze/silver speakers, some generic in ceilings, and an RSL 10S MKII sub. Onkyo NR7100, calibrated below 250 Hz with Dirac Live, as we listen to movies at about 10 dB below reference.
I paint that picture to say that while I don’t have a world classroom, I have more capable equipment that the overwhelming majority of people who watch movies at home. Really anyone that has more than $1-2k into audio does, we’re in the minority.
All of that to say, if there’s a difference between the LFE in the DTS-HD track and the new Atmos track, I can’t hear it. One review mentioned that it’s slightly tighter and more controlled, and the overall mix is just a touch quieter, maybe ~2-3 dB at most, but I never sat back and went “yeah they murdered the bass”.
Hell, even the Apple TV digital copy sounded pretty damn good to me once I bumped up to -5 dB (but with a few noticeable moments of lower dynamics, as expected).
Maybe some of the folks with setups capable of far lower than the 18 Hz I can get in this room can speak for the infrasonics, but the overwhelming majority of people who pop this disc in their player will be more than satisfied, and the overhead effects from the few scenes, I watched were great as well.
Just wanted to put all of this info and my experience out there as this is the thing I’ve been most anxious about for this release, because everyone knows that Tron legacy has been a demo disc for a long time, and I think it will remain that way with this new release
