Ukuchaneka nokungaqiniseki kwee-Audiophile
Thelekisa ixabiso
Ama-Audiophile kunye nabathandi bezomculo abanomdla bayazi kakuhle igama le-KEF kwaye badibanisa kunye neentetho ezifanelekileyo. I-KEF ngumenzi wesithethi saseBrithani esekelwe ngo-1961 nguRaymond Cooke, owayengumjineli wamandla kunye ne-BBC owawuthanda umculo kwaye wazama ukuyila isithethi esingcono sokuvelisa umculo. Phantse kwiminyaka engama-50 kamva, izithethi ze-KEF ziyafumaneka kwiinkqubo zomsindo ezifanelekileyo kunye nokusungulwa kwezikhulumi ze-Q Series, abathandi bomculo abanamathandabuzo athile kodwa i-bajeti ezithobekileyo zinokunandipha iintetho ze-KEF.
Design KEF
IQ50 yi-2 ½-indlela yokuhamba esezantsi kwisitethi se-reflex esiphakathi komgca we-Q uchungechunge ngesandi esilungisa ubuncinane bayo. Ndiyicinga ukuba ingafakwa njengeyinqaba encinane. IQ50 zifakwe ngeengcingo, isakhiwo se-KEF esinciphisa amaza okuma ngaphakathi kwaye iikhabhinethi zikhonjiswe ngaphakathi ukuze zivelise i-enclosure eqinile. IQ50 inomqhubi we-5.25 "5.25", umqhubi we-5.25 "phakathi kwe-bass kunye nokulungelelanisa ngokugqithiseleyo .75" i-aluminium dome tweeter, inxalenye yebali ye-KEF Uni-Q. IQ50s ingaba ne-wired-wire okanye i-bi-amplified.
Uqwalaselo lomqhubi we Uni-Q ngumqondiso we-KEF wesignesha. Idizayini ye-Uni-Q ihambelana ngqo namaza omsindo esuka kwi-midrange kunye ne-tweeter ukudala insimu yomsindo odibeneyo. Amaziko acoustic, okanye iikhoyili zezwi zabaqhubi zilungelelanise ixesha ukwenzela ukuphumeza isithethi 'somthombo wendawo' apho zonke izandi zivela kwindawo enye kwindawo. Ukuphambana phakathi kwamaza okuvakalayo avela kubaqhubi ahlukeneyo kuncitshiswa kwaye iziphumo zinika umgangatho ohambelanayo ophezulu kunye neempawu ezazisasazekayo. Isithethi esivumelanayo sinikela ingqungquthela yesandi njengokungathi uphulaphule umqhubi omnye kuzo zonke iifom, kungekhona abaqhubi abahlukeneyo abadibanisene ne-crossover. Kwamava am, ukusebenzisana ngokukodwa kukunye kwezona zinto zibalulekileyo kwaye zikhange zikhunjulwe ngokuveliswa komculo ochanekileyo.
Udidi lwe-Uni-Q kwiisithethi ze-Q Series luye lwacocwa kwakhona nge-'anger tangerine 'yangasese ejikeleze i-tweeter ekunceda ukulawula nokulawula isandi esivela kwi-tweeter.
Ukuqala kokuqala: iifilimu
Kuthatha ixesha ukujwayelana nesimo sesithethi kunye neempawu ezivakalayo, kodwa okokuqala kubalulekile. Ndiyifumana kukunceda ukuphulaphula ngokukhawuleza ngaphambi kokuba ndibe naliphi na ukuphulaphula ngokugqithiseleyo, kodwa ukucinga kwam kokuqala kwe-iQ50 kwakukho iibhasi zabo ezicacileyo kwaye zichazwe kakuhle kunye nomculo kunye nemithombo ye-movie.
Ubuncwane obuhle kunokuba nzima ukufezekisa nangona xa izithethi zifakwa kakuhle kwigumbi ezineempawu ezilungileyo, kodwa ii-iQ50 zazinobumba obukhulu ngaphandle kwebhokisi kunye nokwandisa kakhulu. Kwakungekho nantlanzi ebonakalayo okanye idipsi kwimpendulo ephantsi yefrikansi kwaye i-bass yandiwa ngokulinganayo kwigumbi.
Icala kwinqanaba liyixesha lesithandathu ye-Fox series '24' (iDVD, iDolby Digital), eyayinomthwalo obuninzi-ukunciphisa ubunzulu obunzulu. Ukuqwalasela ubungakanani babo, ii-KEF zifike ezinzulwini ezinzulu ezingenakwenzeka ngaphandle kwe-subwoofer. Kwakuyinqakrazo ebonakalayo yokubona. Enyanisweni, ndakhangela i-sub sub ukuba ndiqinisekise ukuba ayisebenzi. Ngokuqhelekileyo ndiza kusebenzisa i-subwoofer kwiitrakthi zomsindo ngesitishi se-LFE, kodwa lo luvavanyo olulungileyo lwe-KEF iQ50s yaye lwagqithisa ngokucacileyo.
Iimpawu ezihlalayo: Umculo
U-Mary Black 'uColumbus' kwi-CD yakhe engekho iMida (i-Gift Horse Records), unomgca ophezulu wee-bass ukuba i-KEF iQ50s iveliswe ngokucacileyo nokuqina. I-Diana Krall 'Yeka Indlela Engenakunceda' ('Kusuka Kulo Mzuzu', iCD, iiReve Records) zidibanise kakuhle izitya ezinobunzulu beendawo ezibonakalayo.
IQ50s inepakethe ehamba phambili okanye umoya oza kunye neplagi ye-foam ekhutshweyo kwi-bass esenzekayo inamandla kakhulu ekukhethweni kokuphulaphulwa komntu, kodwa andifumananga kuyimfuneko yokusebenzisa iiplogi.
Ukuhamba ngaphaya kwee-bass, ii-KEF iQ50s zinomgangatho olinganiselayo, olinganiselayo obonisa i-loudspeaker engathathi hlangothi. Amagama kunye namazwi ayenemigangatho yemvelo kunye neendawo eziphezulu zichanekileyo kwaye zichanekileyo kodwa zikhutshwe naluphi na umlenze ophezulu ophezulu okanye u-tizzyness ovame ukugqoka ezindlebeni kwaye ngokukhawuleza kubangele ukukhathala. I-KEF zanikeza ithuba lokuphulaphula eliphucukileyo, elikhululekile lokuphulaphula umculo, masibe nandipha umdlalo ngaphandle kwe-boom-sizzle. Lo mzekelo obalaseleyo wokubambisana ngokufanelekileyo kwaye kwenza ukuphulaphula okungaqhelekanga kunye nokuziphulaphula ngokukhawuleza kwaye kuyonwaba.
Isiphelo
Iintetho ze-KEF iQ50 ziphakathi kwezivakalisi ezilungileyo kakhulu eziye ndazihlaziya kwi-sub-$ 1000 ngamanani amabini ngamabini kwaye ndicaca ukuba kutheni abathandi bezomculo abathandekayo bahlonipha izikhulumi ze-KEF. Iminyaka engama-50 yesiphakamiso sokwakha isithethi kunye nokucocwa kuhlawule. Nangona izithethi ze-KEF zizwakala zikhulu ngemithombo ye-movie, amaphuzu abo anamandla anokwenziwa komculo. Ukungathathi-hlangothi, ukungaqhathaniswa kunye nokulinganisela zimbalwa zeenkcazo endizakuzisebenzisa xa ndishwankathela uhlolo lwam.
Ubungakanani babo bobukhulu bungabonakali kwaye ukulungeleka nokugqiba kweekhabhinethi kuyamangalisa. Emva kokugqiba ezintathu, i-Black Ash, i-Dark Apple kunye ne-American Walnut i-iQ50 iya kudibanisa ngokulula malunga naluphi na umgangatho wesigumbi.
I-KEF isincoma ama-watts ama-15 ukuya kuma-130 ama-iQ50s, kodwa ngobunzulu beempawu eziyi-88 dB (ngokuphantsi), ndiza kuphakamisa i-amp amp okanye i-receiver nge-watts eziyi-100 kwiseshini okanye ngaphezulu ukuze ufumane ibanga elichanekileyo kwi-KEF iQ50s.
