A:Answer Thank you for a great question on our SmartCast™ SB4551-D5!
I apologize, but we do not have a measurement of Watts for our sound bars and sound stands. When dealing with a sound bar or any pre-configured audio system, sound pressure and speaker efficiency are the most important specifications to consider. The sound pressure level will be measured in dB. A higher dB level will determine the performance of the speakers at a higher volume level. This soundbar has a sound pressure level of 104dB, with a frequency range of 30Hz-20kHz.
If you have any questions or concerns, we encourage you to reach out to our Support team at 844.254.8088. Thanks again and have a great day! -Collin
