I couldn't help but notice that with a few exceptions, all of the DVD's that are currently 'bass champions' and feature intense sub 20 Hz bass, such as The Haunting and Titan A.E., are of films released after the Phantom Menace in 1999. By this point, HT and DVD's were starting to pick up. Knowing this, did Hollywood sound designers start placing this ultra deep sub bass in their soundtracks because they finally had a market where people could experience it? very few, if any, commericial theaters can reproduce good bass under 40 Hz, whereas most HT can reproduce down to 30, or in many instances much, much lower. So did DVD and HT technology lead to the now prevalent 'subharminic bass', or is it just a coincidence of one movie (TPM) doing it for the hell of it, and everybody else following the lead? Opinions?
