A:Answer In some home theater setups, users purchase components separately. So, a user would need to purchase a receiver, an amplifier, and individual speakers. When piecing together a home theater system in this fashion it’s important to balance the system. Measuring the wattage each device is capable of transmitting & receiving and the impedance of each device (measured in OHMs) was balanced to achieve the maximum sound pressure level (or volume measured in decibels). Typically, a speaker that can receive a higher wattage are also capable of creating a higher Sound Pressure Level (decibels). It’s important to note that watts is a measure of power, but sound pressure level, (The measure of volume), is the end result. In VIZIO Sound Bar Systems the components are self-contained and balanced, so the wattage transmitted between each internal component is already configured to give you the maximum Sound Pressure Level, which for this Sound Bar is 105 dB.
