ʻO kahi subwoofer (a i ʻole sub) he woofer, a i ʻole kahi leo leo piha, i hoʻolaʻa ʻia no ka hana hou ʻana i nā alapine leo haʻahaʻa i kapa ʻia ʻo bass.
ʻO ka laina alapine maʻamau no kahi subwoofer ma kahi o 20-200 Hz no nā huahana mea kūʻai aku, ma lalo o 100 Hz no ke kani ola ʻoihana, a ma lalo o 80 Hz i nā ʻōnaehana i ʻae ʻia e THX.
Manaʻo ʻia nā subwoofers e hoʻonui i ke ʻano haʻahaʻa haʻahaʻa o nā leo kani e uhi ana i nā kaha alapine kiʻekiʻe.
Hoʻokumu ʻia nā subwoofers i hoʻokahi a ʻoi aku paha nā woofers i kau ʻia i loko o kahi pā leo kani-i hana pinepine ʻia me ka lāʻau-hiki ke kū i ke kaomi ea me ka pale ʻana i ka deformation. Hiki mai nā pā subwoofer i nā ʻano hoʻolālā like ʻole, me ka bass reflex (me kahi awa a i ʻole passive radiator i loko o ka pā), baffle pau ʻole, hoʻouka ʻia nā pū, a me nā hoʻolālā bandpass, e hōʻike ana i nā kālepa kūʻokoʻa e pili ana i ka pono, ka bandwidth, ka nui a me ke kumukūʻai. Loaʻa i nā subwoofer passive kahi mea hoʻokele subwoofer a me ka pā a hoʻohana ʻia lākou e kahi waho Ka hōpili. Loaʻa i nā subwoofers ikaika kahi mea hoʻonui i kūkulu ʻia. Ua hoʻomohala ʻia nā subwoofers mua i ka makahiki 1960 e hoʻohui i ka pane bass i nā ʻōnaehana stereo home. Ua komo nā Subwoofers i ka ʻike kaulana loa i ka makahiki 1970 me ka hoʻokomo ʻana o Sensurround i nā kiʻiʻoniʻoni e like me Earthquake, i hoʻopuka i nā leo haʻahaʻa haʻahaʻa nui ma o nā subwoofers nui. Me ka hiki ʻana mai o ka cassette compact a me ka disc compact i nā makahiki 1980, ʻaʻole i kaupalena ʻia ka hana maʻalahi o ka bass hohonu a me ka leo nui ma muli o ka hiki i kahi stylus phonograph record ke hahai i kahi. ke kani, a hiki i nā mea hana ke hoʻohui i nā ʻikepili haʻahaʻa haʻahaʻa i nā hoʻopaʻa leo. Eia kekahi, i ka makahiki 1990, ua hoʻopaʻa nui ʻia nā DVD me nā kaʻina hana "hoʻopuni" i loaʻa i kahi alapine Low-frequency effects (LFE), hiki ke lohe ʻia me ka hoʻohana ʻana i ka subwoofer i nā ʻōnaehana hale kiʻiʻoniʻoni. I ka makahiki 1990, ua kaulana nui nā subwoofers i nā ʻōnaehana stereo home, nā hoʻonohonoho leo kaʻa maʻamau, a me Pūnaehana PA. Ma ka 2000s, ua lilo nā subwoofers i mea āpau i nā ʻōnaehana hoʻoikaika leo i nā hale pō a me nā wahi ʻaha mele.
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu iā Neaera a me kahi mea kūʻai aku ʻike, makuakāne, a makemake hoʻi e hoʻāʻo i nā mea hana hou me ka guitar ma ka puʻuwai o koʻu makemake, a me kaʻu hui, ua hana wau i nā ʻatikala blog hohonu mai 2020 e kōkua i ka poʻe heluhelu kūpaʻa me nā ʻōlelo aʻoaʻo hoʻopaʻa leo a me nā kīkā.
