You have to know what channels the infra is on before you can even make that claim. Barely make 25 to 30 Hz on what channels?
The main channel speakers in that setting can not go as deep as the LFE/subwoofer channel. A lot of movies have next to nothing below 20 hz on the LFE channel along with plenty on infra on the main channels.
