Ukubukeka Kwezobugcisa Kwii-Ordinary Top Tables Speakers
I-Wirecutter ingandifunela ukuba ndiqhube uvavanyo olubanzi lwezixhobo zesithethi esinezixhobo ezi-2.0, ezenzelwe i-desktop / i-audio audio. Ekuvavanyeni, mna kunye neqela labaphulaphuli lalinganisa amanqaku asibhozo; Kwabakho abathathu abangabandakanyiyo ngenxa yokuba ndicinga ukuba banelungelo lokuthathwa njengeyona nto ibhetele, yesibini-yesibini okanye eyona yesine. Kwaye kwi-Wirecutter, xa usesidlulile sesine-phambili, awukho osebenzayo.
Ngeendlela ezininzi kwindlu yam, andinakuze ndibanqande ukuma endaweni yam yokulinganisa nokubona indlela abaqhuba ngayo kwiimvavanyo zebhu.
Ndikulinganisa impendulo yesantya nganye kwinkqubo nganye, ekunika isalathisi esihle sokuba inkqubo yenziwe njani. Ngokufanelekileyo, impendulo yexesha eliqhelekileyo le-blue trace kwitshathi nganye (ehambelana nomlinganiselo ukusuka kuma-0 degrees, ngqo phambi kwesithethi), iya kuba yiplani okanye isondele kuyo. Ngokuqinisekileyo, ulandelelwano oluluhlaza kwitshathi nganye (ebonisa ukuba umyinge weempendulo kwi-0, ± 10, ± 20 no-± 30 degrees ngokulandelelanayo) iya kuhlulwa kancinane kwicala elincinane kwetshathi, njengoko uvavanyo lwamaxesha alinganiselwa kuma-20 kilohertz, eyona mqathango oqhelekileyo owamkelwayo wokuvalelwa kwabantu.
Ndenze le milinganiselo kusetyenziswa ubuchule be-quasi-anechoic, ngesithethi esiphezulu se-2-meter-high stand kunye neMikrofoni yokulinganisa i-MIC-01 kwiimitha ezili-1, isebenzisa umsebenzi wokuqhayisa kwi-Clio 10 FW yomsindo wokuhlaziya i-audio ukuphelisa imiphumo ye-acoustical yeenxa zonke izinto. Ndatshintsha ukuphakama kwemakrofoni, ngesizathu, ukuzama ukufumana impendulo ephezulu kwisithethi ngasinye. Impendulo ye-Bass yayilinganiswa ngokusebenzisa indlela yokuhamba komhlaba, kunye nemakrofoni emhlabathini 1 imitha phambi kwesithethi, kwaye igalela umphumo kwii-quasi-anechoic kwinqanaba eliphakathi kwe-160 ne-180 Hz. Iziphumo ze-quasi-anechoic zahlanjululwa kwi-octave ye-1/12, i-plane yomhlaba iphumela kwi-octave ye-1/6. Iziphumo zaziqheleke kwi-0 dB kwi-1 kHz.
Ngenzeka, xa ndibala inani le-dB kunye / minus, ndilahle yonke into engaphantsi kwe-200 Hz kuba ukunyuka kwempendulo ye-bass kwisigqibo se-quasi-anechoic sincike kwisilinganiso esithile sokuqagela. Ndibala i-bass umda wokuphendula ngokuthatha i-peak output ngaphantsi kwe-200 Hz nokukhupha -6 dB.

Audioengine A2 + Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza okwesibhakabhaka): ± 3.3 dB ukusuka kwi-82 Hz ukuya kwi-20 kHz
Umyinge (eluhlaza): ± 2.4 dB ukusuka kwi-82 Hz ukuya kwi-20 kHz
Nangona i-A2 + inomdla omkhulu kwi-bass response ephakathi kwe-140 i-Hz, impendulo ngokubanzi iyaphatheka ngokukhawuleza. Ngenxa yokuba ndimisa yonke into kwi-0 dB kwi-1 kHz, ibonakala ngathi i-A2 + ine-midrange ephakamileyo ephakamileyo kunye nempendulo ejikelezayo, kodwa ngokwenene into enayo i-midrange di-diamange ye--3 dB phakathi kwe-400 Hz ne-1.5 kHz.

Bose Companion 20 Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza okwesibhakabhaka): ± 6.2 dB ukusuka kwi-56 Hz ukuya kwi-20 kHz
Umyinge (oluhlaza): ± 6.6 dB ukusuka kwi-56 Hz ukuya kwi-20 kHz
Umlinganiselo wesilinganiselo se-Companion 20 uhamba ngokwenene-kodwa lo mlinganiso usezingeni eliphantsi, ngoko ungalindelanga amandla amakhulu ukusuka kwisithethi. Impendulo yesantya ibonakala ibuhlungu kakhulu. Njengesiqhelo, uBose akabonakali ukuba umqhubi uyakunyusa kwizinto zakhe zokuthengisa, kodwa oku kubonakala ngathi impendulo yokuphendula yomqhubi omnye, opheleleyo.

Iimpawu ze-Creative GigaWorks T40 Series II
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza okwesibhakabhaka): ± 4.7 dB ukusuka kwi-90 Hz ukuya kwi-20 kHz
Umlinganiselo (eluhlaza): ± 4.9 dB ukusuka kwi-90 Hz ukuya kwi-20 kHz
Nangona i-GigaWorks T40 ine-balanceal tonal ye-tonal, ngokumalunga namaxabiso emandla phakathi kwee-mids kunye ne-treble kunye ne-bass boost ukuze igcine ingabonakali kakuhle, impendulo phakathi kwe-1.4 no-5.5 kHz ibonakala ibuhlungu kakhulu.

Edifier Eclipse Measurements
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza okwesibhakabhaka): ± 5.4 dB ukusuka kwi-57 Hz ukuya kwi-20 kHz
Umyinge (eluhlaza): ± 4.5 dB ukusuka kwi-57 Hz ukuya kwi-20 kHz
Nantsi isithethi esilinganisa njengam. Nangona i-Eclipse's response response ihamba ngokujulile (kubonga kwii-radiator zayo ezincinane) kwaye i-midrange ihamba phambili, impendulo ephakamileyo ngaphezu kwe-3 kHz yintoni eyenza esi sithethi isandi "sesandi" esicacile ekuhlolweni.

Ukuqulunqa i-Spinnaker Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (bluhlaza): ± 2.5 dB ukusuka kwi-61 Hz ukuya kwi-20 kHz
Umyinge (eluhlaza): ± 2.6 dB ukusuka kwi-61 Hz ukuya kwi-20 kHz
Ngoku sithetha. I-spinnaker iyalinganisa malunga nokufa-iflethi. Uninzi lwezivakalisi eziphakamileyo azilinganisi kakuhle. Kakade, i-Spinnaker ine-digital signal processing processing eyenza ukuba iphumelele ukufumana impembelelo enjalo.
Ngokuqinisekileyo, izithethi ezincinci ezinjengezi vavanyo apha zifanele zilinganise isicatshulwa kuba ukusasazeka kwabaninzi be-woofers kunokudibanisa kangcono kunye nee-tweeters. Isizathu sokuba baninzi babo abalinganisi isicatshulwa mhlawumbi ukuba iinjineli babengenayo ibhajethi eyaneleyo yokubeka intanethi ye-crossover efanelekileyo kwisithethi, okanye mhlawumbi kwezinye iimeko abazange bazame ngokwenene nzima okanye kunethuba lokubethela impela uyilo. NgeSpinnaker kubonakala kulula kuba yindlela yokuyila e-3 nge-tweeter ye-3/4-intshi, i-midrange ye-2-3 / 4 intshi kunye ne-4-intshi yoofer.

I-Grace Digital GDI-BTSP201 Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza): ± 5.0 dB ukusuka kwi-72 Hz ukuya kwi-20 kHz
Umyinge (oluhlaza): ± 4.8 dB ukusuka kwi-72 Hz ukuya kwi-20 kHz
Njengoko ndiphawule ekuphononongweni kwam kwangoko, imilinganiselo ye-GDI-BTSP201 ibonakala ilula kakuhle ukuya kwi-3 kHz, kodwa ibuhlungu kakhulu ngaphezu kwayo.
08 we-11
I-Logitech Z600 Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza okwesibhakabhaka): ± 5.8 dB ukusuka ku-71 Hz ukuya kwi-20 kHz
Umyinge (oluhlaza): ± 5.2 dB ukusuka ku-71 Hz ukuya kwi-20 kHz
I-Z600 inokunyuka ngokukhawuleza impendulo ejikelezayo ukuya kwi-5 kHz, enokuthanda ukuyibeka isandi esicacileyo, kwaye ayinayo impendulo ebhaliweyo ekufuneka ilandele ukutshisa.

I-M-Audio Studiophile AV 40 Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis (eluhlaza): ± 4.2 dB ukusuka kwi-78 Hz ukuya kwi-20 kHz
Umyinge (eluhlaza): ± 3.9 dB ukusuka kwi-78 Hz ukuya kwi-20 kHz
I-AV 40 ayifani ngokukhawuleza njengoko ndikulindelwe, kwaye i-bass yayo ayifani ngokujulile njengoko ndalindelanga-nangona i-woofer yayo eninzi imele ivumele ukuba idlale ngokubanzi phezulu kwii-frequencies kunezinye iincinci ezincinci apha. Sekunjalo, ibhalansi yonke ye-bass ukuya kwi-midrange ukuhamba ihamba ngokufanelekileyo, mhlawumbi kunye namandla angaphezu kwamanqanaba angaphantsi kunye ne-low treble, phakathi kwe-1.8 ne-6 kHz.
