The most conspicuous one over the last couple of weeks was during the broadcast of the baseball world series, is the Verizon 4G LTE advertisement.
The skydivers taking balls of thunder and then dropping them on to the earth while skydiving gives you some pretty good bass.
I smiled EVERYTIME this ad was played since, this is the most bass I have noticed during and OTA broadcast. A friend was more than impressed. Told him, you should really watch the action movies on this setup.
