100 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other AV receivers and amplifiers, soundbars, home theater speakers, subwoofers, surround sound systems and Blu-ray players we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Miroir SL3100 measures 24.34 x 1.56 x 2.96 inches, making it one of the slimmer bars at this price point. That compact profile is useful if your TV cabinet or wall space is tight, and the included wall-mount hardware means you can get it off the shelf without extra accessories.
HDMI is the sole listed connection, which keeps setup simple if your TV has an ARC port but rules out optical or Bluetooth sources entirely. At 390W rated output the numbers look strong relative to the $79.99 price, though rated power figures vary widely by measurement standard and should be treated as a relative indicator rather than an absolute comparison.
With 100 ratings and a 4.1-star average, early buyer sentiment is cautiously positive. The review pool is still thin enough that the score could shift as more feedback comes in, so it is worth watching recent reviews before buying.

Performance notes
Rated at 390W with a 2-channel (2.0) configuration through a single HDMI connection. Dimensions are 24.34 x 1.56 x 2.96 inches and the bar is wall-mountable. No subwoofer is included, so bass output depends entirely on the bar's built-in drivers.
What buyers say
Buyers give the SL3100 a 4.1-star average across 100 ratings. That score suggests general satisfaction with core audio performance at this price, but the small sample size means individual experiences could vary more than a larger pool would indicate.

Frequently asked questions
Does the Miroir SL3100 work with any TV?
It connects via HDMI, so it works with any TV that has an HDMI ARC port. If your TV lacks ARC, you will need an adapter or a different soundbar with optical or aux input. Always check your TV's available ports before purchasing.
Is the SL3100 easy to wall mount?
At 1.56 inches tall and under 3 pounds, it is one of the lighter bars in this price range and designed with wall mounting in mind. The slim profile keeps it close to the wall. Standard mounting hardware is included, though you will still need appropriate wall anchors for your surface type.
Does it include a subwoofer?
No. The SL3100 is a 2.0 soundbar with no subwoofer in the box. Bass response will be limited compared to a 2.1 system. If low-end output matters to you, consider pairing it with a separate powered subwoofer or choosing a 2.1 kit instead.
