Ukusizwa Okuncane Emithethweni Yezemvelo
I-SVS, inkampani eyaziwa ngokukhethekile kuma-subwoofers iminyaka engaphezu kwengu-20, ivele isethule amamodeli amabili amasha aphakathi kwawo, i $ 699 SB-2000, engisanda kuyihlola, futhi i $ 799 PB-2000 . Bobabili basebenzisa i-amplifier entsha engu-500-watt ye-RMS Class D kanye nomshayeli we-inch 12-in-up-up .

I-SB-2000 ingumklamo obhalwe uphawu, kanti i-PB-2000 ihanjiswa. I-PB-2000 inkulu kakhulu, izikhathi ezingu-2.7 umthamo we-SB-2000.
Njengomklamo oveziwe, i-PB-2000 ingalindelwa ukuba ibe nempendulo ejulile, kodwa i-rolloff ehamba phambili emazingeni angaphansi kwe-resonance yayo ye-acoustical. I-subsed subs ejwayele ukuba nemisipha eminingi engezansi kune-subs seal, futhi ijwayele ukuzwela nokukhishwa okukhulu. Kodwa-ke, ngezinye izikhathi abanalo i-punch nencazelo ye-subwoofers engcono kakhulu.
Ngakho ake sizithole ukuthi lokhu okukhulu, okungenzeka kube yimuphi okubi kakhulu kuqhathaniswa nomzalwane wakhe obhalwe uphawu.

Ku-synthpop iqembu elithi "Falling" lika-Olive - umsindo ohlosekayo wokuthi iSB-2000 wadlala ngokumangalisayo ngokucabangela ubukhulu bawo - i-PB-2000 ayizange ibuyele nje amanothi, cishe yayizizwa njengezintambo ezinkulu ohlelweni lwe-PA club enhle , ngaphandle kokuzikhandla, amandla angokwenyama eluhlaza kanye ne-tray of distortion.
Kuthatha ithrekhi yokuhlola ekhulu kakhulu, ukurekhodwa kwe-Saint-Saëns 'Symphony No. 3 "I-Organ Symphony" kusukela ku-CD ye-Boston Audio Society Test, ukuthola imingcele ye-PB-2000 - nakuba ngisho nje lokho kwasusa kancane yendawo yayo yokududuza. Amanothi angu-16 ama-Hz aphansi kakhulu akhiqiza ukuphazamiseka okuncane kodwa i-ton of chair chair and emotion visceral ukuthi ekuhlangenwe nakho kwami kungadlula yi-subs kuphela enkulu kakhulu, njenge-Hsu VTF-15H noma i-PC13-Ultra ye-SVS. Amanothi aphansi kakhulu akhiqiza umoya osuka echwebeni, i-thoiugh, into engake ngahlangana nayo esikhathini esilandelayo esilinganisweni sami se-CEA-2010A.
Ama-Movie akuyona into yami kakhulu lapha kwi-About.com Stereos; yilapho isifundazwe sase-About.com Home Theater Expert ikhasi likaRobert Silva. Kodwa ngangiqhubeka nginikeza i-PB-2000 i- Star Wars, Isiqephu II: Ukuhlaselwa kwamaClones , okuqala ngamabhasi ajulile futhi anamandla njenge-yacht isikhala esiphezulu eqhuma phezulu bese iqhuma. I-PB-2000 yazibophezela ngokuphelele lolu luvivinyo oluyinselele, yaxosha isihogo esihlalweni sami futhi izwakala sengathi yayidabula umoya ngaphandle.

Ishadi elingenhla limelela impendulo yokulinganisa imvamisa ye-PB-2000 nge-fressover frequency efakwe esiphezulu (ukulandelana okuluhlaza) no-80 Hz (umkhondo omude). Ngalinganisa le mpendulo ngokuvala imoto umshayeli kanye nechweba, ukulinganisa ukulinganisa ichweba nokuyifakela ngesilinganiso sechweba. Amathuluzi ami kwakuyisicwaningi somsindo se-Audiomatica Clio 10 FW kanye nomakrofoni we-MIC-01 wokulinganisa.
Ngenza izilinganiso ze-CEA-2010A ngendlela efanayo ne-SB-2000, ngisebenzisa imakrofoni yomhlaba we-Earthworks M30, isikhombimsebenzisi sami se-M-Audio Mobile Pre USB kanye nesofthiwe ye-freeware ye-CEA-2010 eyenziwe nguDon Keele, egijima ku-Wavemetric Igor Pro isofthiwe yesayensi yesayensi. Ngathatha lezi zilinganiso emkhatsini wemikhawulo engu-2 yamaprekhi, bese ngifinyelela ku-1-mitha elinganayo ngezimfuneko zokubika ze-CEA-2010A. Izilinganiso ezimbili ezilinganiselwe engizenzile lapha - i-CEA-2010A kanye nendlela yendabuko - zisebenza ngokufanayo, kepha isilinganiso sendabuko esetshenziswa amawebhusayithi amaningi alalelwayo nabakhiqizi abaningi kubika imiphumela emlinganisweni we-RMS wamamitha amabili, okungukuthi -9 dB ephansi kune-CEA-2010A. I-L eceleni komphumela ibonisa ukuthi okukhiphayo kwashiwo yizifunda zangaphakathi ze-subwoofer (ie, limiter), hhayi ngokudlula imigqa ye-CEA-2010A yokuhlanekezela. Amaphesenti abalwa kuma-pascals.
Lezi zilinganiso ezinhle kakhulu zokukhiqizwa kwe-subwoofer engu-12 intshi, $ 799. Bawela cishe -4 kuya ku -6 dB amahloni ngalokho engikulinganise kusukela ekubambeni okukhulu kakhulu kunabo bonke, kepha ukuphendula kwempendulo kanye nokukhipha kulo lonke uhla lokusebenza oluphansi kuyamangalisa, futhi okukhiphayo cishe kuningi ngisho nakakhulu abathanda ukuhlala ekhaya bangasebenzisa.
Kodwa-ke, ku-20 Hz, kunomsindo wesiphakamiso ekuhlolweni kwe-CEA-2010A. Cishe ngeke uzwe lokhu ngoba kunokuqukethwe okuncane okungama-Hz emculweni nasemabhayisikobho, kodwa ngezwi le-CEA-2010A 20 Hz, lizwakala njengendlovu ephethe amasondo.
