The DN15 proved to be a crowd-pleaser with movies. When watching discs with soundtracks that dip below 20Hz such as Pacific Rim, The Haunting, and The Polar Express (the train sequence), I was able to rattle the windows and let the neighbors know it was movie night. Playing the embassy attack scene from 13 Hours: The Secret Soldiers of Benghazi, the .50 caliber blast from the sniper rifle was loud, sharp, and impactful—just like it’s supposed to be.

Another great demo to see how deep a sub can go is the “soften them up” scene from the Hacksaw Ridge Ultra HD Blu-ray. When the destroyer opens fire to shell the battlefield, multiple shots are fired in sequence. The DN15 was able to keep pace with the rapid fire, and it never sounded strained or overmatched. Well done, Def Tech!
