This design minimizes pinpoint localization of the speakers themselves, enhancing the illusion that sound is coming from all around you, just like in a commercial cinema. Whether it’s subtle ambient effects or explosive action sequences, the PRO-7800-S-THX delivers enveloping, detailed surround sound.
