2 Smart TV Audio Systems Overview

Smart TV audio systems usually requires the entire audible range of frequencies, which is beyond the capability of any single mid-power (<30 Watt) speaker. The mid-power speaker operating frequency range is 100Hz to 18 kHz. Therefore, high-end TVs often combine several drivers to make more realistic sounds by designing line-out with an active external woofer with lower resonance frequency of 20Hz.
