I have just listened to the first 30 mins of Flight of the Phoenix and the bass quality is absolutely awesome. During the flight through the sand storm the bass appears to be at very low frequencies for long periods with some peaks hitting 110db at 3m listening position, unlike most films where the bass effects are mostly short duration low frequency effects. It would be be interesting to know how low these bass notes reach. This is certainly my new reference bass film. I would warn you to play it at a lower volume level initially just in case it wrecks your sub's driver.
