There has been a drawn out discussion on bass / LEF level from DVD of Harry Potter, The Chamber of Secrets and LOTR Fellowship of the Ring. What about LOTR, The Two Towers? I was wondering if anyone has noticed any lack of bass / LEF level at the moment of explosion of Helms Deep wall in that movie. It is a visually spectacular explosion but as I watched 3 times with different adjustments on my sub, it all seem to lack the punch that makes the good sub owners smile. Other DVD like Star Wars, Attack of the Clones has that punch, especially at the beginning when the senator Amedala’s shuttle craft explodes.

Would it be that The Two Towers has lower frequency than my sub can respond and end up not being heard during that explosion? I am confident that my sub can do well down to 20 Hz (Shiva driver, 5 cu. ft. enclosure & 150 watt plate amp). Its just my gut feeling that such a scene should really rock the floor but it didn’t which was disappointing.

Any advice on this?
