The film "War of the Worlds(2005)" has effects going down to 20 Hz; to play it you will need an ATMOS AV receiver that has an LFE port to feed the signal to an amp that has LFE input.
Not all amps which have an LFE input can cleanly output 20 Hz, let alone anything lower, so you would need to check the specs.
I wouldn't be surprised to discover that the original "Iron Man" movie reproduced effects at that level, but I know the "War of the Worlds" film does.

- vGPU 3y agoThere’s a difference between sub out and LFE. Sub out usually can’t accurately do frequencies that low. I believe LFE is Dolby tech too.
