Ngaba kuthatha ingqondo?
Ndakukhunjuzwa nje ukuba kunzima kangakanani ukufaka i- subwoofer kwinkqubo ye stereo. Ndakuva i-Revel Performa3 kwinkqubo yesithethi, kwaye yayiquka i-subwoofer ye-B110 - enye yezinto ezimbalwa ezimbalwa Ndiye ndazibona ukuba i-adjustable, in-crossover ukuze ihlukanise iifom ephantsi kwicandelo eliphantsi kwaye lihluze i-bass deep izithethi eziphambili.
Wonke ummkeli we-A / V kwimarike unokwakheka kwe-subwoofer eyakhelwe ngaphakathi, kwaye ininzi yawo ikuvumela ukuba ulungelelanise iphuzu le-crossover-oko kukuthi, i-frequency engezantsi apho isandi sithunyelwa kwi-subwoofer, kwaye ngasentla isandi sisithunyelwe izithethi. Kodwa ndicinga nje ngabamkeli abambalwa be-stereo, ama-amps adibeneyo kunye neempampu ezinokwakheka ngaphakathi.
Ngokuqinisekileyo, phantse yonke i-subwoofer ene-powered e-crossover eyakhelwe ngaphakathi, kodwa ininzi yabo ihluza kuphela i-midrange kwaye ihamba nge-subwoofer. Iifayile ezicwangcisiweyo ezithethi zivela kwiintetho zakho eziphambili, kodwa ngokuqhelekileyo kwixesha elithile eliqhelekileyo.
Ngoko yintoni ingxaki? Ewe, indawo ehleliweyo ye-crossover point is 80 Hz. Oko kusebenza kakhulu ngezithulu eziphambili, kodwa izothumela izitya ezincinci kwiintetho ezincinci, zibenza ziphazamise kwaye mhlawumbi zimele okanye zichithe kwangaphambili. Ukuba i-crossover point is higher, yitsho i-120 Hz, leyo ingasindisa izithethi ezincinci kodwa ingashiya "imingxuma yomsindo" phakathi kwezona zincinci nezithethi eziphambili. Okanye kungenza amazwi amaninzi avela kwi-subwoofer, eya kwenza wonke umntu aqale ukuvakala njengoBarry White.
Okubi nakakhulu ukuba i-subwoofer ayinayo indlela yokucoca iifom eziphantsi eziphambili zithethi-apho izithethi eziphambili ziza kuphazamiseka ukusuka kwiindawo eziphantsi kakhulu. Njengabafana abakhankanya i-stereos yabo yemoto ngendlela ephakamileyo.
Ngeprogram yokusetha ungasebenzisa kwi-PC, i-revel B110 yangaphakathi ye-crossover ingasetwa kuyo nayiphi na imvama oyifunayo. (Uyabona iphaneli yejack ye-B110 kwisithombe esingentla.) Umgca wecala kuphela kukuba kufuneka usebenze uxhulumaniso lwenqanaba lomgca kwi-preamp yakho kwi-subwoofer uze ubuye kwi-amp amp. Ukuba awunayo i-preamp ecacileyo kunye ne-amp, uya kufuna umntu owamkelayo okanye udibanise ne-preamp ngaphandle / amandla amp jacks.
Enye ibanjwa yi-B110 ibiza.
Kutheni, xa isicatshulwa sokulahla sipakisha uluhlu lokuhlamba iimpahla zedijithali eziphambili kwiimvume ezizithengiyo ezinjenge- Sony STR-DH830 , akunakukwazi ukwakha i-subwoofer eguquguqukayo elula kwi-stereo preamp okanye i-subwoofer enexabiso elidibeneyo? Ndisakwazi ukuyijonga.
Ngaba usebenzisa i-subwoofer kunye nesistim sakho se stereo? Ukuba kunjalo, unokwenza njani? Masixelele kwicandelo lamaNgxelo apha ngezantsi.
