What specific audio quality challenge in exhibition venues did THX aim to solve by focusing on the final presentation?

Answer

The "last mile" problem of audio quality.

The concept central to the initial THX implementation was addressing what is termed the "last mile" problem regarding audio quality. This phrase signifies the challenge of ensuring the meticulously crafted master recording successfully traversed the final stage—from the playback equipment in the theater to the listener's ears—without degradation. Before THX, there was no unified system to enforce the necessary acoustic prerequisites (like correct calibration and high-quality components) at the exhibition site, meaning expensive post-production work could be entirely undermined by poor playback conditions.
