Ukusebenzisa iMilinganiselo yokuCima i-Controversy
Xa ndibhale inkcazo yam yokuqala ukuba ndiphande ukuba ngaba iziphumo zezicatshulwa zesithethi kwisantyenzana sithethi zingalinganiswa, ndandibonisa ukuba ukutshintsha izixhobo zesikhulumi kunokukwazi ukuba nemiphumo evakalayo kwisandi senkqubo.
Kulo vavanyo, ndasebenzisa imimiselo eyingozi kakhulu: umzekelo, i-cable gauge-24 nge-12 gauge cable. Uninzi lwabafundi bezibuza ukuba luhlobo luni lomahluko endingayilinganiselayo xa ndiqhathanisa ikhebula le-12-gauge ikhebula kwisikhethi esiphakamileyo sesithethi. Ndazibuza,.
Ngoko ndathatha iinqonga eziphakamileyo, ndiboleke ezinye iintambo eziphakamileyo eziphezulu ezihlobo, kwaye ndaphinda ndivavanye uvavanyo.
Ukuphinda ubuyisele indlela yokuvavanya: Ndasebenzisa i-analyzer yomsindo we-Clio 10 FW kunye ne-microphone ye-MIC-01 ukulinganisa impendulo yenye yee-Revel Performa3 ze-F206 izivakalisi. Ukulinganiswa kwamagumbi ekufuneka ukuba kuqinisekiswe ukuba bekungekho nto ingxolo engqongileyo. Ewe, ukulinganisa kwamagumbi kubonisa imiphumo emininzi yegumbi le-acoustics, kodwa oko kwakungekho nkcazo kuba apha, ndandifuna kuphela umgama kwimiphumo elinganisiweyo xa ndatshintsha iimbambo.
Kwaye ukuphinda uphinde uphinde ulandele le ngcamango emva kwalokhu: Iziqhubi zesithethi kunye nezixhobo zengqungquthela zenza isixhobo sokucoca sombane esixakekileyo esilungele ukunika isithethi isandi esifanelekileyo. Ukongeza ukuchaswa, ngesimo sekhefu yesithethi esiphezulu, kuya kutshintsha ii-frequencies apho uhluzi lusebenza khona kwaye ngoko utshintshe impendulo yesantya yesithethi. Ukuba ikhebula longeza i-inductance okanye amandla kuloluhlu lwefayile, ngoko, naloo nto inokuchaphazela isandi.

Uvavanyo 1: I-AudioQuest ne-QED kunye ne-12-Gauge
Kwiimvavanyo zam, ndalinganisa imiphumo yamacandelo ephakamileyo aphezulu ekude ubude be-10 ukuya kwi-12 ubude kwaye ubufanise nomlinganiselo kunye nekhefu yesigidi se-12-gauge yesithethi. Ngenxa yokuba imilinganiselo yezona zihlandlo zifana noko, ndiya kuzibonisa apha ezintathu ngexesha, kunye neentambo ezimbini eziphezulu eziphambili ngokubhekiselele kwikhebula le-generic.
Ireyiti apha ibonisa i-cable generic (i-trace blue), ikhebula le-AudioQuest ye-4 (umkhondo obomvu) kunye nekhefu le-QED ye-Silver Anniversary (ulandelelwano oluhlaza). Njengoko uyakubona, kuba inxalenye enkulu ukungafani kuyinto encinci kakhulu. Enyanisweni, ukuhlukana kakhulu kunomlinganiselo oqhelekileyo, umlinganiselo omncinci wendlela yokulinganisa owufumanayo xa wenza imilinganiselo yee-transducers zomsindo ngenxa yokulandelela ubuninzi bezandi, ukutshintsha kweempawu kubaqhubi, njl njl.
Kukho umahluko ophantsi kwe-35 Hz; iicandelo eziphezulu eziphezulu zivelisa imveliso engaphantsi kwe-bass kwisithethi esingaphantsi kwe-35 Hz, nangona umahluko ku--.2.2 dB. Akunakwenzeka ukuba oku kuya kuphulaphulwa, ngenxa yokunyaniseka kwendlebe kuluhlu; ukuba ininzi umculo ayinakho umxholo amaninzi kuloluhlu (ukuthelekisa, inqaku elincinane kunazo zonke kuma-guitars asezantsi kunye neziseko ezizithe tye yi-41 Hz); kwaye kuba kuphela izikhulumi ezinkulu zentonga zinemveliso engaphantsi kwe-30 Hz. (Ewe, unako ukongeza i-subwoofer ukuba uhambe ngaphantsi, kodwa phantse bonke abo baxhaswe amandla kwaye ngoko akunakuchaphazeleka yithethi yesikhulumi.) Uyakuva umahluko omkhulu kwi-bass response ngokuhambisa intloko yakho 1 unyawo kunoma iyiphi na indlela.
Andizange ndifumane ithuba lokulinganisa iipropati zombane zekhebula le-AudioQuest (loo mntu wayeyifuna kwakhona ngokukhawuleza), kodwa ndayilinganisa ukuchaswa kunye nokuxhotyiswa kwee-QED kunye neentambo zendalo. (Ukukhutshwa kwezixhobo kwakuphantsi kangangokuba i-Clio 10 FW iyilinganise.)

Uvavanyo lwe-2: I-Shunyata neProtected-End Prototype vs. 12-Gauge
Le ngqungquthela elandelayo ivelise ikhebula eliphezulu eliphezulu: i-1.25-intshi ye-Shunyata yophando i-Etron Anaconda kunye ne-cable engama-0.88-inch-thick prototype ephuhliswayo kwinkampani ephezulu yokulalelwayo. Zombini zibonakala zikhudlwana kuba zisebenzisa i-tubing eboyiweyo ukumboza iingcingo zangaphakathi, kodwa kunjalo, zombini zinzima kwaye zibiza. I-Shunyata Reserach ikhebula ihamba malunga nama-5,000 / ididi.
Ishati apha ibonisa i-cable generic (i-trace blue), i-cable ye-Shunyata yophando (umkhondo obomvu) kunye nomboniso ongekho igama elingu-high-end cable (ulandelelwano oluhlaza). Nantsi imilinganiselo yombane:
U-Shunyata wophando u-Etron Anaconda
Ukuchasana: 0.0020 Ω nge-ft.
I-Capacitance: 0.020 nF ngeenyawo
Iprototype ephezulu
Ukuchasana: 0.0031 Ω nge-ft.
I-Capacitance: 0.038 nF ngeenyawo
Apha siqala ukubona ukungafani, ngakumbi malunga ne-2 kHz. Makhe sondeza ngokujonga ngakumbi ...

Uvavanyo lwe-2: Zoom View
Ngokwandisa ubukhulu bexabiso (dB) kunye nokunciphisa umda womda, sinokubona ukuba ezi zixhobo ezinkulu, ezinobunzima zivelisa umlinganiselo olinganayo kwimpendulo yesithethi. I-F206 isithethi se-8-ohm; Ubukhulu balo mmahluko kuya kukwanda nge-4-ohm isithethi.
Akukho umda omkhulu-ngokuqhelekileyo ukukhuliswa kwe-+0.20 dB kunye ne-Shunyata, +0.19 dB kunye nomzobo-kodwa uhlanganisa uluhlu lwee-octaves ezintathu. Ngesithethi se-4-ohm, amanani kufuneka abe kabini, ngoko +0.40 dB yeShunyata, +0.38 dB yeprototype ..
Ngokutsho kophando olukhankanyiweyo kwinqaku yam yokuqala , i-Q-high (ii-high-bandwidth) zokuboniswa kwe-0.3 dB ubukhulu zinokuzwakala. Ngoko ngokutshintshela kwikhebula eliqhelekileyo okanye i-cable-gauge-end end-cable ekupheleni kwelinye lala macala amakhulu, ngokuqinisekileyo kungenzeka ukuba umehluko unokuvakala.
Uthini lo mahluko? Andazi. Unokwenza okanye ungenako ukuyiqonda, kwaye kuya kuba yinto efihlakeleyo ukuthetha okungenani. Andiyi kucacisa ukuba ngaba kuya kuphucula okanye kuhlaziye isandi sesithethi; kuya kuphakamisa ukuhamba, kunye nezinye izithethi eza kuba zilungileyo kwaye abanye bekungaba kubi. Qaphela ukuba ukunyanga kwamagumbi okunyusa amayeza ayeza kuba nempembelelo enkulu.

Uvavanyo 3: IsiGaba
Ngenxa yokufuna ukwazi, ndaphinda ndiqhathanise isantya sokutshintshwa kwesigaba esibangelwa iimbambo, kunye nekhefu ye generic eluhlaza okwesibhakabhaka, i-Audioquest ebomvu, i-prototype eluhlaza, i-QED kwi-orange kunye ne-Shunyata ebomvu. Njengoko ungakubona ngasentla, akukho shintsho esicatshungulwayo kwisigaba ngaphandle kobukhulu becala. Siqala ukujonga imiphumo engaphantsi kwe-40 Hz, kwaye ivela ngaphezulu ibonakala phantsi kwe-20 Hz.
Njengoko ndithe ndandulela ngaphambili, le miphumo mhlawumbi ayinakuvakala kakhulu kubantu abaninzi, kuba umculo omningi awunakho umxholo amaninzi kwii-frequencies ezinjalo, kwaye ezininzi izithethi azinalo mveliso phakathi kwe-30 Hz. Sekunjalo, andinakuthi ngokuqinisekileyo ukuba ezi ziphumo ziya kuba zizwakala.

Ngabe i-IT Speaker Cables yenza umehluko?
Ziziphi iimvavanyo ezibonisa ukuba abantu abakugxinayo abakwazi ukuva umahluko phakathi kwezicatshulwa zombini ezahlukeneyo zesilinganisi esingafanelekanga. Kunokwenzeka ukuva ulwahlulo ngokutshintsha izixhobo.
Ngoku, loo nto ithetha ntoni kuwe? Ngokuqinisekileyo kuya kuba buqhetseba. Njengoko ukuthelekiswa okungafihlisiyo kwezixhobo zesithethi eziqhelekileyo esizenzayo kwiThe Wirecutter kuboniswe, kwimeko apho abaphulaphuli banokuva ukuhluka phakathi kweethala, ukufunwa kwaloo mahluko kuya kutshintsha kuxhomekeke kwisithethi oyisebenzisayo.
Ukususela kule mivavanyo evumelekileyo, ibukeka kum njengemibono enkulu ekusebenziseni intambo yesithethi kubangelwa ngokukodwa kumlinganiselo wokumelana kwi-cable. Ulwahlulo olukhulu ndililinganise lunezixhobo zombini ezazincitshiswa kakhulu kunabanye.
Ewe, izithethi zesithethi zingatshintsha isandi senkqubo. Akuninzi. Kodwa banokutshintsha ngokuqinisekileyo isandi.
