THX CERTIFIED LOUDSPEAKERS
With home theater, sound is everything. Crisp clean audio drives the emotional depth, texture and immediacy envisioned by the artist. THX Certified Loudspeakers pass hundreds of lab tests to guarantee precisely this level of performance every time.
WHAT WE TEST
THX ENGINEERS COMPLETE HUNDREDS OF DIFFERENT SCIENTIFICALLY-FORMULATED TESTS TO ENSURE THE HIGHEST AUDIO VISUAL STANDARDS POSSIBLE. KEY TESTS IN THIS PROGRAM ARE AS FOLLOWS:AXIAL FREQUENCY RESPONSE
This describes a loudspeaker’s ability to reproduce audio accurately. Our test confirms the axial frequency response is balanced and flat.VERTICAL AND HORIZONTAL DISPERSION
Not everyone gets the middle seat when watching a movie. So we test the off-axis response to make sure it is smooth with no audible comb filtering, making every seat in the room the sweet spot.OUTPUT VS. DISTORTION
This test ensures the speaker can reach the high volumes necessary to achieve THX Reference Level without creating audible distortion or artifacts.
