The perfect movie to test it on is Fellowship Extended Edition. The DTS-ES track. The first chapter where there's the ring drop. If you play the ring drop scene on all large you'll get virtually no to little bass on DTS-ES or if you have your sub turned up you'll get bass, but it cuts off right before the helmet drops. But, if you play them in small (particularly your surrounds (channels 4&5) you'll hear the bass extend further right up to where the helmet drops. A fascinating discovery I thought.
