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:

testing loudspeakers

SUBWOOFER

All THX Certified speaker bars must have a subwoofer combined with the speaker bar, that can reproduce audio frequencies from 35Hz to 20,000Hz and maintain an accurate, flat frequency response.

FREQUENCY RESPONSE

Many speaker bar systems do not have a flat frequency response extending to 35Hz, which can result in parts of the audio track becoming inaudible.

BOUNDARY GAIN

THX Certified Speaker Bars must have a boundary gain setting to account for frequency boost when the speaker bar is mounted on a wall or table. This ensures that wall mount and table-top applications sound natural.
