Ukubukwa Kwezobuchwepheshe Abathengisi Abakhulu Bakamuva Bekhompyutha
I-Wirecutter yangibuza ukuthi ngenze ukuhlolwa okujulile kwezinhlelo zesiphakamiso eziphethwe amandla, 2.0-isiteshi eklanyelwe ideskithophu / ikhompyutheni yomsindo. Esivivinyweni, mina kanye neqembu labalaleli laqhathanisa amamodeli angamatshumi ayisishiyagalolunye; kwakukhona amanye amathathu engangabandakanyi ngoba ngangicabanga ukuthi banamathuba amaningi okukhethwa njengendlela engcono, yesibili-engcono noma yesine-engcono kakhulu. Futhi ku-The Wirecutter, uma usuqedile okwesine-okungcono, awuphelile.
Ngamahlelo amaningi kangaka endlini yami, angikwazi ukumelana nokubeka esimweni sami sokulinganisa nokubona ukuthi benza kanjani ekuhlolweni kwebhu.
Ngilinganise ukuphendula kwevama kwesistimu ngayinye, okukunikeza isibonakaliso esihle sokuthi uhlelo luhle kangakanani. Okufanelekile, impendulo yevamenti ye-trace eluhlaza okwesibhakabhaka eshadini ngalinye (okuhambisana nesilinganiso esivela ku-degrees 0, ngqo phambi kwesipikha), kungaba flat noma eduze nayo. Futhi, ukulandelana okuluhlaza eshadini ngalinye (okubonisa ukuthi isilinganiso sezimpendulo ku-0, ± 10, ± 20 no-± 30 degrees ngokulinganayo) kuzohlehliswa kancane ngakwesokudla kweshadi, njengoba imvamisa yokuhlola ifinyelela ku-20 kilohertz, okuyinto imingcele evamile yokwamukela ukuzwa kwabantu.
Ngenza lezi zilinganiso ngisebenzisa indlela ye-quasi-anechoic, ngesiphakamiso esisezingeni eliphakeme lamamitha amabili nemikrofoni yokulinganisa i-MIC-01 kumitha engama-1, ngisebenzisa umsebenzi wokubamba umcwaningi womsindo we-Clio 10 FW ukuqeda imiphumela ye-acoustical yezungezile izinto. Ngishintshe ukuphakama kwemakrofoni, ngaphakathi kwesizathu, ukuzama ukuthola impendulo enhle kusuka kusikhulumi ngasinye. Impendulo ye-bass yayilinganiswa ngokusebenzisa imigwaqo yasemhlabathini, nomakrofoni emhlabathini 1 imitha phambi kwesipikha, bese ukufaka umphumela emaphethini we-quasi-anechoic endaweni ephakathi kuka-160 no-180 Hz. Imiphumela ye-quasi-anechoic yabuyiselwa ku-octave yehora le-12/12, imiphumela yezindiza yomhlaba ifika ku-1 / 6th octave. Imiphumela yenzeke ku-0 dB ku-1 kHz.
Ngesinye isikhathi, uma ngibala izinombolo ze-dB / plus, ngilahla konke ngezansi kwe-200 Hz ngoba ukukala kwempendulo ye-bass ekuphenduleni kwe-quasi-anechoic kuncike ekudleni okuthile ngokuqagela. Ngibala umkhawulo wempendulo ye-bass ngokuthatha umkhiqizo omkhulu ngaphansi kwe-200 Hz nokukhipha -6 dB.

Audioengine A2 + Izindlela
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 3.3 dB kusuka ku-82 Hz kuya ku-20 kHz
Isilinganiso (green): ± 2.4 dB kusuka 82 Hz kuya 20 kHz
Nakuba i-A2 + ine-hump iningi ekuphenduleni kwe-bass ephakathi kuka-140 Hz, ukuphendula konke kubonakala kuphephile. Ngenxa yokuthi ngiyinto evamile yonke into ku-0 dB ku-1 kHz, kubonakala sengathi i-A2 + ine-midrange ephakeme ephezulu kanye ne-response, kodwa ngempela into enayo i-midrange dip of cishe -3 dB phakathi kuka-400 Hz no-1.5 kHz.

Bose Companion 20 Izinyathelo
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 6.2 dB kusuka ku-56 Hz kuya ku-20 kHz
Isilinganiso (green): ± 6.6 dB kusuka 56 Hz kuya 20 kHz
Isimpendulo esilinganisiwe se-Companion 20 siyajula kakhulu - kepha lesi silinganiso sisezingeni eliphansi, ngakho ungalindeli amandla amakhulu okuvela kulesi sikhulumi. Impendulo yemvamisa ibukeka ihle kakhulu. Njengokwejwayelekile, uBose akadalula ukuthi umshayeli uhambelana nezinto zokuthengisa, kodwa lokhu kubonakala sengathi impendulo yokuphendula yomshayeli oyedwa, ogcwele.

Izinyathelo ze-Creative GigaWorks T40 Series II
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 4.7 dB kusuka ku-90 Hz kuya ku-20 kHz
Isilinganiso (green): ± 4.9 dB kusuka 90 Hz kuya 20 kHz
Nakuba i-GigaWorks T40 ine-balanceal ye-tonal ephelele, cishe cishe amanani amaningi wamandla phakathi nendawo ehambahambayo kanye ne-bass boost ukuze igcine ingabonakali kahle, impendulo ephakathi kuka-1.4 no-5.5 kHz ibonakala inzima kakhulu.

Ukulinganisa kwe-Edifier Eclipse
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 5.4 dB kusuka 57 Hz kuya ku-20 kHz
Isilinganiso (green): ± 4.5 dB kusuka 57 Hz kuya 20 kHz
Nasi isikhulumi esilinganisa njengathi sazwakala kimi. Ngenkathi impendulo ye-Eclipse igxila ngokujulile (ngenxa yama-radiator akhe amabili) futhi i-midrange iyabushelela, impendulo ephakeme ngaphezu kwe-3 kHz yilokho okwenza lesi sikhulumi sibe umsindo "we-sizzly" engiwuphawulile ekuhlolweni.

I-Edifier Spinnaker Izinyathelo
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 2.5 dB kusuka ku-61 Hz kuya ku-20 kHz
Isilinganiso (green): ± 2.6 dB kusuka 61 Hz kuya 20 kHz
Manje sikhuluma. I-Spinnaker iyalinganisa cishe ngokufa-flat. Izikhulumi eziningi eziphezulu kakhulu azilinganisi kahle lokhu. Yiqiniso, i-Spinnaker ine-signal yedijithali yokucubungula ngaphakathi okuyivumela ukuba ifinyelele imiphumela enhle kakhulu.
Ngesinye isikhathi, izikhulumi ezincane ezinjengalezo ezihlolwe lapha kufanele zilinganise isicaba ngoba ukuhlakazeka okubanzi kwe-woofers encane kungaxhuma kangcono ngama-tweeters. Isizathu esiningi kakhulu esingazilinganisi esicacile kungukuthi onjiniyela babengenawo isabelomali esanele sokubeka inethiwekhi efanele ye-crossover kwisipikha, noma mhlawumbe kwezinye izimo abangazange bazame kanzima ngempela noma abazange bakwenze unesikhathi sokuzibophezela ngempela umklamo. Nge-Spinnaker kungcono nakakhulu ngoba yindlela yokuklama emithathu nge-tweeter ye-3/4-intshi, i-midrange ka-2-3 / 4 intshi kanye ne-woofer engu-4 intshi.

Izinyathelo ze-Grace Digital GDI-BTSP201
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 5.0 dB kusuka 72 Hz kuya ku-20 kHz
Isilinganiso (green): ± 4.8 dB kusuka 72 Hz kuya 20 kHz
Njengoba ngibonile ekubuyekezeni kwami kwasekuqaleni , izilinganiso ze-GDI-BTSP201 zibukeka zibushelelezi kuze kufike ku-3 kHz, kodwa zihlezi kahle ngaphezu kwalokho.

Izinga le-Logitech Z600
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 5.8 dB kusuka ku-71 Hz kuya ku-20 kHz
Isilinganiso (green): ± 5.2 dB kusuka 71 Hz kuya 20 kHz
I-Z600 inempendulo ehamba phambili kancane kancane efika ku-5 kHz, engathanda ukuyibeka umsindo ozwakalayo, futhi ingenayo impendulo ye-bass idinga ukulinganisa ukuhamba okushisayo.

I-M-Audio Studiophile AV 40 Izindlela
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 4.2 dB kusuka ku-78 Hz kuya ku-20 kHz
Isilinganiso (green): ± 3.9 dB kusuka 78 Hz kuya 20 kHz
I-AV 40 ayilinganisi njengebushelelezi njengoba ngangilindele, futhi ama-bass ayo ajulile njengoba ngangilindele - nakuba i-woofer yayo ekhululekile kufanele ivumele ukuthi idlale ngokushelela emazingeni aphansi kunezinye izikhulumi ezincane lapha. Noma kunjalo, ibhalansi yonke yama-bass kuya phakathi kwe-midrange ehamba kahle ihamba kahle, mhlawumbe kancane kwamandla angaphezu kwamaphakathi nendawo ephansi, phakathi kuka-1.8 no-6 kHz.

Ukulinganisa kwe-PSB Alpha PS1
Impendulo yephindaphindiwe
I-on-axis (eluhlaza okwesibhakabhaka): ± 4.0 dB kusuka ku-76 Hz kuya ku-20 kHz
Isilinganiso (green): ± 2.9 dB kusuka 76 Hz kuya 20 kHz
I-Alpha PS1 inempendulo enhle kakhulu ngaphandle kwalokhu kuphakama kwe-octave-wide okugxile ku-1.6 kHz. Yebo, kune-resonance enkulu ye-tweeter ku-18 kHz, kodwa ngaphandle uma usencane nentombazane, cishe awukwazi ukuyizwa.
