Monitor Audio SB-4

The SB-4 may look like an oversized version of a regular sound bar, but this passive speaker is engineered with Monitor Audio's premium cabinet and driver technologies for truly high-performance home theater. The high-density MDF cabinet is internally braced, creating a rigid, low-resonance enclosure. Inside you'll find 4" woofer cones and 1" dome tweeters that are made of C-CAM — a high-tech ceramic-coated aluminum/magnesium alloy. This exceptionally stiff, lightweight material allows the drivers to respond swiftly and precisely to the audio signal for greater accuracy. The tweeters also get an anodized coating of gold that helps ensure smooth, extended highs. The bar has three separate driver arrays. The left and right channels each include a single tweeter, dual mid/bass drivers, and an ABR (Auxiliary Bass Radiator). The center channel has the same, but with an extra ABR.
