"An inexpensive upgrade from tinny TV speakers, sold on features rather than audio fidelity."
The '190W Peak Power' is a theoretical, split-second maximum. The actual sustained volume and clarity will be defined by the undisclosed RMS power, making it suitable for a bedroom or small living room, not a large home theater space.
This is for someone on a strict sub-$100 budget whose only goal is to get sound that is louder and has more body than their TV's built-in speakers. Its versatile connections, especially direct USB audio, also make it a viable option as an amplified desktop speaker system.
Anyone seeking convincing surround effects, deep movie-rumble bass, or high-fidelity music playback should save up for a model from an established audio brand. The use of a 'peak power' spec and lack of codec information indicates this is not engineered for discerning listeners.
