Ama-Subwoofers aqala ukwaziwa kakhulu ngeminyaka yawo-1970s ngokwethulwa kwe-Sensurround kumamuvi afana ne-Earthquake, eyakhiqiza imisindo ephezulu ye-low-frequency ngokusebenzisa ama-subwoofers amakhulu. Ngokufika kwekhasethi elihlangene kanye ne-compact disc ngawo-1980, ukukhiqizwa kalula kwamabhesi ajulile futhi anomsindo kwakungasanqunyelwe ikhono lokuloba irekhodi legilamafoni ukulandelela ingoma. inkatho, futhi abakhiqizi bangangeza okuqukethwe okuvama kancane kokurekhodwayo.
