I-subwoofer (okanye i-sub) yi-woofer, okanye i-loudspeaker epheleleyo, enikezelwe ekuvelisweni kwee-audio ezisezantsi ezibizwa ngokuba yi-bass.
Uluhlu oluqhelekileyo lwe-frequency ye-subwoofer malunga ne-20-200 Hz kwiimveliso zabathengi, ngaphantsi kwe-100 Hz yesandi esiphilayo sobugcisa, kwaye ngaphantsi kwe-80 Hz kwiinkqubo ezivunyiweyo ze-THX.
Ii-Subwoofers zenzelwe ukunyusa uluhlu oluphantsi lwezandisi-lizwi ezigubungela iibhendi zamaza aphezulu.
I-Subwoofers yenziwe nge-woofers enye okanye ngaphezulu efakwe kwi-enclosure ye-loud-speaker-ehlala yenziwe ngamaplanga-ekwaziyo ukumelana noxinzelelo lomoya ngelixa ixhathisa i-deformation. I-Subwoofer enclosures iza kwiindidi ezahlukeneyo zoyilo, kubandakanywa i-bass reflex (ene-port okanye i-radiator passive kwi-enclosure), i-baffle engapheliyo, i-horn-loaded, kunye ne-bandpass designs, emele i-tradeoffs ekhethekileyo ngokubhekiselele ekusebenzeni kakuhle, i-bandwidth, ubukhulu kunye neendleko. I-Passive subwoofers inomqhubi we-subwoofer kunye ne-enclosure kwaye inikwe amandla ngumntu wangaphandle amplifier. I-subwoofers esebenzayo ibandakanya i-amplifier eyakhelwe-ngaphakathi. Ii-subwoofers zokuqala zaphuhliswa kwi-1960s ukongeza impendulo ye-bass kwiinkqubo ze-stereo zasekhaya. I-Subwoofers yeza kwingqondo edumileyo ngeminyaka yoo-1970s ngokwaziswa kwe-Sensurround kwiimuvi ezinje nge-Earthquake, nethe yavelisa izandi ezivakalayo ezisezantsi ngee-subwoofers ezinkulu. Ngokufika kwekhasethi ehlangeneyo kunye necwecwe lecwecwe ngeminyaka yee-1980, ukuphinda kuveliswe ngokulula kweebhasi ezinzulu nezingxolayo kwakungasathintelwa kukukwazi kwesimbo serekhodi yegramafoni ukulandelela irekhodi. emseleni, kwaye abavelisi banokongeza umxholo ophantsi kakhulu wokurekhodwa. Kananjalo, ngeminyaka yee-1990s, ii-DVD zaye zarekhodwa ngokwandayo ngeenkqubo “zesandi esijikelezileyo” ezibandakanya isitishi se-Low-frequency effects (LFE), esinokuviwa kusetyenziswa i-subwoofer kwiinkqubo zethiyetha yasekhaya. Ngexesha lee-1990s, ii-subwoofers ziye zanda kakhulu kwiinkqubo zestereo zasekhaya, ufakelo lwemoto yesiko, kunye nakwi. Iinkqubo ze-PA. Ngeminyaka yoo-2000, ii-subwoofers ziye zaphantse zafikelela kwindalo yonke kwiinkqubo zokuqinisa isandi kwiiklabhu zasebusuku kunye neendawo zekonsathi.
