Uncedo oluncinci kwiMithetho yeFizikiki
I-SVS, inkampani ekhethekileyo kwi-subwoofers iminyaka engaphezu kwe-20, ivele ivelise imodeli emibini emitsha, i-$ 699 i-SB-2000, endiyifundileyo , kunye ne-799 ye- PB-2000 . Bobabini basebenzisa i-amplifier entsha ye-RMS ye-500-watt ye-500-watt kunye nomqhubi we-inch 12-intshi . Kwaye ngokuqhelekileyo ukufundiswa kwetyala kwindlela i-subwoofer yokudibanisa i-enclosure yokwenza ngayo ingashintsha ngokubanzi isandi sayo.
I-SB-2000 iyilwe-bhokisi yokutywinwa, ngelixa i-PB-2000 ifakwe. I-PB-2000 inkulu kakhulu, ngamaxesha angama-2.7 umthamo we-SB-2000.
Njengendlela yokuyila, i-PB-2000 ilindeleke ukuba ibe nempendulo enzulu, kodwa i-rolloff ehamba phambili kwii-frequencies phantsi kwe-acoustical resonance. I-posted subs edla ukuba nemisipha emininzi engaphantsi komgca kunokuba i-sealled subs, kwaye ithambekele ekubeni nobuzwe obukhulu kunye nemveliso ephezulu. Nangona kunjalo, ngamanye amaxesha abanalo i-punch kunye nenkcazo ye-subwoofers elungileyo.
Ngoko makhe sifumene ukuba le nto inkulu, inokuba yinto engalunganga iyafana njani nomzalwana wayo.

Kukho ipakethe yePB-2000 efana ne-SB-2000. Bobabini akunikezi izinto ezintle, kodwa ndiyakholelwa ukuba ukuba uxhuma i-subwoofer kumkeli we-A / V, kwaye usebenzisa i-reciever ukwenza i-crossover (isiphaluka sihamba ngeendlela eziphantsi kwe-subwoofer kunye ne-mids kwaye zihamba kwiintsimbi zesithethi ), akunakudingi kakhulu kunokuba ulawulo lwezinga.
Njengoko unokulindela, ukusetha kwakufana ne-SB-2000. Ndiyifake i-PB-2000 eklasini lam "indawo epholileyo" - indawo apho ndivavanya phantse yonke i-subwoofers-kwaye ndixhume i-LFE yokufaka kwi-subwoofer yam yomkeli we-Denon. Emva koko ndatshintshisa ibhalansi yeseshini kwaye ndafika ngokuvavanya. I-point of crotsover endiyikhethile yayiyi-80 Hz xa ndidibana ne-PB-2000 kunye ne-Revel Performa3 F206 izithethi zentonga kunye ne-Monitor Audio Radius 270 yesitishi somninindlu , kunye ne-100 Hz xa ndidibene ne-PB-2000 nge- Sonance SB46 L

I-SVS PB-2000: Ukusebenza
Funda "Iimvavanyo ze-Stereo zoMdlalo ezi-10 zam intandokazi" malunga nolwazi oluninzi malunga kunye neesampuli zam izinto zokuvavanya.
Ukuphonononga i-PB-2000, ndayifanisa ne-SB-2000 kunye ne-reference subwoofer, i-Hsu Research VTF-15H esetyenziswe kwiimodeli ezivulekileyo kunye ne-1-port-open.
Xa ndizongena nge-Holly Cole ukuguqulelwa kukaTom Waits '"Qeqesha ingoma," ndiyakuva ngokukhawuleza ukuba iPB-2000 ihluke njani kwi-SB-2000. Inqaku lokuqala likaDavid Piltch elungileyo, elingabangela ukuba abanye baphambuke, i-PB-2000 yadlala ngaphandle kokuphazamiseka okuzwakalayo, kunye ne-welcom-shakin power power. Njengoko uPiltch wangena kumanqaku aphakamileyo kwinqanaba lakhe, nangona, ndakuva ukuba i-PB-2000 ayinayo inkcazo ephakathi nendawo ephezulu kunye nephunga le-SB-2000.
I-"Aja" kaSteve Dan yanikela umphumo ofanayo. I-PB-2000 ihlambulukile kwaye ichanekile, ayizange idlulisele ubuninzi bomlingisi we-gitare ye-bass-ithoni, ubuqili obuqhayisayo, njl. Kodwa kwavakala kunelisekile kunokuba i-SB-2000, idlala ngokulula amanqaku apho umncinci omncinci obunqamlekileyo unzima kakhulu.
Kwiqela le-synthpop "I-Falling" ye-Olive-into efuna ukuba i-SB-2000 idlale ngokumangalisayo ngokucokisekileyo ubukhulu bayo - i-PB-2000 ayizange ivelise nje amanqaku, iphantse ive ngathi i-woofers enkulu kwi-club ye-PA , ngokungazimeli, amandla anesibhakabhaka emzimbeni kunye nary trace of distortion.
Kwathatha umkhondo wokuvavanya kakhulu, ukurekhoda kweSaint-Saëns 'Symphony No. 3 "I-Organ Symphony" ukusuka kwi-CD yeBoston Audio Society Test, ukufumana imida ye-PB-2000 - nangona loo nto yayingqongqo yendawo yokuthuthuzela. Amanqaku angama-16 eHz aphantsi avelisa ukuphazamiseka okuncinci kodwa itoni ye-chair and shake feeling that in my experience can exceeded by only the largest, like Hsu VTF-15H okanye i-SVS ye-PC13-Ultra. Amanqaku aphantsi kakhulu avelisa umoya omkhulu ukusuka echwebeni, ke, into endiyifumana kamva kwimiqathango yam ye-CEA-2010A.
Iifilimu azikho nto yam apha apha kwi-About.com Stereos; ngaba kunjalo iphondo le-About.com Home Theater Expert iphepha likaRobert Silva. Kodwa ndiqhube phambili kwaye ndinike iPB-2000 i- Star Wars, isiqendu II: Ukuhlaselwa kwamaClones , okuqala ngeenqwelomoya ezinzulu kunye ezinamandla njengendawo yokukhusela i-yacht iqhuma phezulu. I-PB-2000 yayibethelela ngokupheleleyo le mvavanyo ecelomngeni, inyikima isihogo ngaphandle kwesitulo sam kunye nokuvakala ngathi kwakunokuqhawula umoya ngaphandle. Ndandimangalisile kangangokuba ndabhala kwimiba yam, "Yiyo yonke into endiyifunayo kwi-home subtitles." Qaphela ukuba ndathi "... into endiyifunayo ..." kuba andizange ndiyidlale ngokukhawuleza ngexesha lonke. Ukuba wenza njalo, kufuneka uqwalasele i-subwoofer enkulu, okanye mhlawumbi ukongeza i-PB-2000 yesibili.
Ndacinga ukuba i-PB-2000 idibanise kakuhle neentetho zam Revel F206 ze-Revel, kodwa ngenxa yokungabi naso kwe-punch bass, andizange ndicinge ukuba ngumdlalo omkhulu kwi-soundbar ye-Sonance SB46 L, ehamba phambili 100 Hz subwoofer i-fressover frequency. Ukuba uxubungela isicatshulwa sakho kunye nezinye izibhengezo ezisisigxina, okanye ukuzisebenzisa kwigumbi elincinci (lithetha, ii-2,000 cubic feet okanye ngaphantsi), i-SB-2000 mhlawumbi ibhetele engcono kuwe.

Isalathiso esingentla sichaza impendulo ephindaphindiweyo yempendulo ye-PB-2000 kunye nesantya sobume esetyenziswe kwisisigxina (ulandelelwano oluhlaza) kunye ne-80 Hz (umkhondo omnxeba). Ndayilinganisa le mpendulo ngokuvala imida umqhubi kunye nechwep, ukulinganisa ukulinganisa kwefowuni nokuyifumanisa kunye nesilinganiselo sefowuni. Izixhobo zam ziyi-Audiomatica Clio 10 I-analyzer ye-FW kunye ne-microphone ye-MIC-01.
Ndenza i-CEA-2010A imilinganiselo ngendlela efanayo ne-SB-2000, usebenzisa i-microworks M30 yokulinganisela imakrofoni, i-M-Audio ye-Mobile Pre Pre interface kunye ne-freeware ye-CEA-2010 software eyenziwa nguDon Keele, osebenza kwi-Wavemetric Igor Pro software yesayense. Ndithatha le milinganiselo kwi-2 m mveliso yesiqhamo, ke ke ndayifumanisa ukuya kwi-1-mitha elinganayo kwiimfuno ze-CEA-2010A zokubika. Iisethi ezimbini zeemilinganiselo endizibonayo apha - i-CEA-2010A kunye neendlela zendabuko-zisebenza ngokufanayo, kodwa umlinganiselo wendabuko oqeshwe yiwebhu ezininzi ezilalelwayo kunye nabakhiqizi abaninzi iingxelo ziphumo ezilinganayo kwi-R-meter ye-RMS elinganayo, eyi -9 dB ephantsi kune-CEA-2010A. I-L ngokubhekiselele kwiphumo ibonisa ukuba umkhiqizo wawucaciswe ngabaphathi bee-subwoofer zangaphakathi (okt, i-limiter), kwaye kungekhona ngokugqithisa i-CEA-2010A. Umyinge ubalwa kuma-pascals.
Ezi ziyimilinganiselo emihle yokuvelisa i-subwoofer ye-12-intshi, i-$ 799. Bawela ngokukhawuleza -4 ukuya kwi -6 dB neentloni zento endikulingayo ukusuka kwona mkhulu kunabo bonke, kodwa ukunyameka kwempendulo kunye nesiphumo kulo lonke uluhlu lokusebenza luchukumisayo, kwaye umphumo mhlawumbi uninzi kakhulu abathanda umdlali basekhaya bangasebenzisa.
Nge-20 Hz, ke, inomsindo wesango kwi-CEA-2010A vavanyo. Mhlawumbi awuyi kuva le nto kuba kunomxholo omncinci we-Hz kumculo nakwiimabhayisikobho, kodwa nge-tone ye-CEA-2010A ye-Hz ye-20 ye-Hz, itywina njengendlovu enomkhuhlane.

I-SVS PB-2000: Thatha ekugqibeleni
I-PB-2000 i-subwoofer evelele. Iza kusebenza kwezona zinto zingcono kakhulu; Ukwahlukana okukuphela kwakho oza kukuva kuthiwa yimveliso encinane engaphantsi kweDB. Kodwa ngokunyanisekileyo, usenokungaphuthelwa loo nto, ngaphandle kokuba ungumhlobo oqhuba i-subwoofer egcweleyo yonke ixesha kwaye abukele nto ngaphandle kwee-movie zenzo.
Ndikhetha i-SB-2000 nje ngomculo, kodwa i-PB-2000 ye-muscle ecocekileyo kwi-octave ephantsi kakhulu ye-bass, ukususela kuma-20 kuya ku-40 Hz, yenza ukuba kukhethwe ngokukhethekileyo xa unayo indawo.
