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.

Who it's for
A good match for anyone wanting a slim, wall-mountable soundbar upgrade over built-in TV speakers, connected through a single HDMI cable. Less suited to buyers who specifically want a separate subwoofer or surround speakers included, since none are listed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- Slim, low-profile bar fits under most TVs
- Single HDMI connection for setup
- No subwoofer or surround speakers listed as included
- Real-world output at 390 watts depends on measurement method not specified
Performance notes
A single HDMI connection keeps setup simple, passing audio and, depending on the TV, control signals through one cable rather than a separate optical or RCA hookup.
