Overview
Rated at 390 watts and built for wall mounting, the Miroir SL3100 soundbar connects to a TV or receiver through a single HDMI cable. At 24.34 inches wide and just 1.56 inches tall, its low-profile bar sits under most TVs without blocking the screen.
390 watts is a substantial power rating for a soundbar this thin, though how that translates to real output depends on how the wattage is measured, a detail not included in this listing.

Pros and cons
