Polk Audio SoundBar 400 CHT passive soundbar

Thin, but only in size, never in performance. Just 2 1/2-inches deep!
Inside the sleek enclosure sit ten specially engineered Dynamic Balance®
drivers. Seven 2 3/4-inch composite mid-woofers, designed for high
performance in a shallow-space enclosure, feature powerful neodymium
magnets ensure smooth frequency response throughout a wider soundstage.
Three 3/4-inch high performance silk polymer dome tweeters ensure
realistic imaging and superior detail whether you watch TV, movies, or
games. SDA® technology allows this single-speaker driver array to
deliver an awesomely spacious and realistic soundstage in any room
setup.
