Under $200 Sound Bars

Yamaha today announced two new sound bars, models SR-C20A (23-inch, $179.95) and SR-B20A (36-inch, $199.95). Both include built-in subwoofers, numerous sound modes, including virtual surround sound and Clear Voice technology for enhanced dialogue clarity. The C20 is smaller and contains one built-in subwoofer versus two on the B20A. Also, the B20A adds a subwoofer output.

Along with control by an existing TV remote (when connected via HDMI), each sound bar comes with its own remote and is supported by the Sound Bar Controller App for smartphone control. Easy access buttons on top of the C20A and B20A allow for quick control of volume levels, sound modes and input selection on the units themselves. Although both include HDMI-ARC, neither supports 4K pass-thru so 4K TV owners should use the optical input (requires optical output on 4K TV).

Both sound bars can be placed on a cabinet or shelf, or wall-mounted via the built-in keyholes. No additional bracket is required.

The C20A distinguishes itself from other compact sound bars with its focus on audio and connectivity. Powerful sound is delivered from a built-in subwoofer and dual passive radiators. The combination is a rarity in the realm of compact sound bars, exerting a surprising amount of bass, especially given its size. Four customizable sound modes (standard, stereo, game, movie) are available, in addition to a virtual surround mode. The breadth of connection options also differentiates the C20A from other compact sound bars, with HDMI ARC, optical and aux to connect and control the sound bar with your TV remote, leaving no source unconnected.

At just 23″ long and 2.5″ high, the C20A is designed to fit modern life where space is limited, including gamer stations, bedrooms, offices, playrooms and dorms. It can discreetly fit in front of any screen without obstructing the action or be easily wall-mounted.

SR-C20A Features

  • Connections: HDMI ARC, Optical (x2), Analog stereo mini input for gaming consoles and other portable devices, Bluetooth (including multi-point functionality to switch between devices, including Alexa)
  • Speaker drivers: 2 full-range, 1 subwoofer, 2 passive radiators
  • Sound modes: Stereo, Standard, Movie, Game
  • Clear Voice for dialogue clarity
  • Dolby Digital and Virtual Surround
  • 23″ wide and 2.5″ tall; tabletop or wall-mountable

The B20A appears to replace the identically sized YAS-108 sound bar which also includes built-in subwoofers and DTS Virtual:X. Yamaha claims the dual built-in subwoofers in the B20A have been redesigned for richer and clearer bass. Aesthetically, the B20A sports a new shape and slim profile, with sleek, deep black fabric and larger, dimmable LEDs for visibility of sound bar functions and adjustments.
