Subwoofers inoumbwa neimwe kana akawanda mawoofer akaiswa muvharidziro yegudzanzwi-kazhinji inogadzirwa nematanda-inokwanisa kumirisana nemhepo yekumanikidza ichiramba deformation.

Nekuuya kwekombikiti kaseti uye compact disc kuma1980s, kudhindisa kuri nyore kwemabhesi akadzika uye ane ruzha kwakanga kusisina kuganhurirwa nekugona kwechinyoreso chegiramufomu rekodhi kuronda Groove, uye vagadziri vanogona kuwedzera zvimwe zvakaderera frequency zvemukati kune zvakarekodhwa. Zvakare, mukati me1990s, maDVD aiwedzera kurekodhwa ne "sound sound" maitiro aisanganisira Low-frequency effects (LFE) chiteshi, iyo yaigona kunzwika uchishandisa subwoofer mudzimba dzemitambo masisitimu.
