Audiophiles thiab avid suab paj nruag paub cov KEF lub npe zoo thiab nyob qib qub nrog cov lus nrov zoo nrov. KEF yog ib lub tuam txhab British hais lus tsim hauv xyoo 1961 los ntawm lig Raymond Cooke, tus qub hluav taws xob engineer nrog cov BBC uas nyiam cov suab paj nruag thiab sim ua tus tsim kev hais lus zoo dua rau kev luam suab paj nruag. Yuav luag txog tsib caug xyoo tom qab ntawd, KEF cov lus hais tseem muaj nyob rau hauv cov suab zoo thiab nrog cov lus qhia txog Q Series, suab paj nruag lovers nrog cov cwj pwm tab sis ntau lub pob nyiaj siv tau txais kev lom zem KEF tham.
KEF Tsim
Lub iQ50 yog 2 ½-txoj kev sib npaug hauv cov lus hais tawm hauv theem nrab ntawm Q series nrog lub suab uas nws qhov me me. Kuv kaj lias nws yuav tau classed ua ib tug mini pej thuam. Cov iQ50 enclosures yog nkhaus, tus yam ntxwv KEF tsim qhov uas ua kom tsis txhob muaj kev tsis sib haum thiab cov khoom txig rau sab hauv los tsim ua ib qho khoom, muaj suab nrov nyob hauv tsev. Lub iQ50 muaj 5.25 "tus tsav tsheb thauj neeg tsav tsheb, 5.25" tus tsav tsheb nruab nrab ntawm tus neeg tsav tsheb thiab kev sib tw ua ke. "" Aluminium dome tweeter, ib feem ntawm KEF Uni-Q zaj dab neeg. "IQ50s tseem tuaj yeem siv tau los yog ob qho tib si.
Tus neeg tsav tsheb Uni-Q tsav yog lub npe KEF technology. Uni-Q tsim precisely aligns lub suab tsis ua los ntawm nruab nrab thiab tweeter los tsim ib lub suab sib sau ua ke. Cov chaw nruab nrab, los yog lub suab nrov ntawm cov tsav tsheb yog sijhawm ua ke kom ua tau raws li 'point source' hais lus qhov twg tag nrho cov suab tawm los ntawm tib qho chaw hauv qhov chaw. Kev cuam tshuam ntawm lub suab tsis tau los ntawm ntau tus tsav tsheb yog qhov tsawg thiab cov txiaj ntsim muab ib qho kev xyuam xim suab zoo nrog cov yam ntxwv dav dav. Ib tus neeg hais lus muaj peev xwm nthuav tawm lub suab yoj suab li yog tias mloog ib tus neeg tsav tsheb rau tag nrho cov frequencies, tsis cais cov tsav tsheb sib txuas ntawm qhov crossover. Hauv kuv txoj kev paub, lub suab sib haum yog ib qho tseem ceeb tshaj plaws thiab feem ntau tsis nco qab txog cov suab paj nruag.
Uni-Q array nyob rau hauv Q Series tham tau ntxiv refined nrog ib tug 'tangerine' waveguide puag ncig lub tweeter uas yuav pab tau ncaj qha thiab tswj lub suab los ntawm lub tweeter.
Thawj Kev Txhim Kho: Tsos
Nws yuav siv sij hawm los paub tus neeg hais lus tus cwj pwm thiab tus cwj pwm zoo, tiam sis thawj zaug zoo siab yeej tseem ceeb. Kuv pom tias nws yuav pab mloog cov suab qee yam ua ntej koj mloog lus tseem ceeb, tab sis kuv lub tswv yim ntawm qhov iQ50s yog qhov ua tau zoo heev thiab tau txais kev qhia zoo nrog ob lub suab paj nruag thiab yeeb yam.

Tsis muaj kev pom tseeb los yog dips hauv cov lus teb tsis tshua muaj neeg teb thiab bass suab nrov quaj qw faib thoob plaws hauv chav.
Ib rooj plaub hauv taw qhia yog lub caij rau ntawm lub Fox series '24' (DVD, Dolby Digital), uas muaj ntau yam tsis txaus siab-inducing tob bass. Xav txog lawv cov me me, lub KEFs mus txog qhov tob hauv qhov ntswg tsis muaj qhov subwoofer. Nws yog ib qho kev tsim ceeb ua rau pom kev. Qhov tseeb, kuv tau soj ntsuam kuv lub sub kom paub tseeb tias nws tsis khiav hauj lwm. Feem ntau kuv yuav siv lub subwoofer rau suab khiav nrog lub LFE channel, tab sis qhov no yog ib qho kev xeem zoo ntawm KEF iQ50s thiab lawv meej meej dhau.
Lasting Impressions: Suab paj nruag
Mary Black's 'Columbus' los ntawm nws Tsis Yog Frontiers CD (Pob Khoom Sau Npe Khoom Plaub Ntug), muaj txoj kev khiav tsheb ciav hlau uas ua rau KEF iQ50s muab coj los ua cov ntsiab lus thiab ceev ceev. Diana Krall lub 'How Insensitive' ('Los Ntawm No Lub Caij Ntawm', CD, Verve Cov Ntaub Ntawv) ua ke zoo-txhais cov bass nrog spot-on center imaging.
Cov iQ50s muaj qhov chaw nres tsheb rau pem hauv ntej los yog lub qhovrooj uas tawm nrog cov roj hmab ua ntsaws rau hauv kev tshwm sim bass thaj tsam zoo heev rau tus kheej nyiam mloog, tab sis kuv tsis pom nws tsim nyog siv cov plugs.
Tsiv tshaj li cov ntses bass thaj tsam, cov KEF iQ50s tau muaj kev sib luag, zoo txaus tias bespeaks lub suab nrov nruab nrab tsis nrov nrov. Mids thiab cov suab nrov muaj ib lub voj voog thiab lub siab tshaj plaws yog cov ntsiab lus thiab meej, tab sis averted txhua qib high-end sizzle los yog tizzyness uas mob hnav rau lub pob ntseg thiab sai sai rau hauv kev mloog nkees. Lub KEFs tau txais ib qho kev muag heev, kev mloog kev hnov lus zoo, qhov zoo tshaj plaws uas peb nyiam cov suab paj nruag tsis muaj qhov boom-sizzle. Nws yog ib qho piv txwv zoo ntawm lub suab sib haum thiab nws ua rau kev mloog zoo thiab tseem ceeb heev uas tsis muaj kev sib tham thiab muaj kev lom zem.

Cov KEF iQ50 tham yog cov lus zoo tshaj plaws uas kuv tau nyeem nyob rau hauv sub-$ 1000 rau ib tus nqi khwv nyiaj thiab nws yog qhov tseeb rau kuv vim li cas cov neeg nyiam suab paj nruag txaus siab rau KEF cov neeg hais lus. Xyoo tsib cuaj xyoo ntawm kev hais lus tsim kev tshawb fawb thiab kev txhawj xeeb tau them. Txawm hais tias KEF tau hais lus zoo heev nrog cov yeeb yam yeeb yam, lawv cov ntsiab lus tseem ceeb muaj suab paj nruag kev luam. Neutral, uncolored thiab balanced yog ob peb ntawm cov lus piav qhia kuv yuav siv los nthuav qhia kuv cov kev ntsuam xyuas.
Lawv cov kev cog lus me me tsis muaj kev sib haum xeeb thiab txoj kev haum zoo thiab qhov kawg ntawm cov khoom yog qhov muaj nqis. Nrog peb cov khoom tiav, Dub Tshauv, Tsaus Kua thiab American Walnut lub iQ50s yuav muab cov khoom yooj yim nrog rau txhua lub chaw dai khaub ncaws.
KEF pom zoo 15 - 130 watts rau lub iQ50s, tiam sis nrog ib qho kev tshaj tawm ntawm 88 dB xwb (kuj tsis tshua muaj), kuv xav kom ib tug amp lossis receiver nrog 100 watts ib channel los yog ntau tshaj qhov tau txais ntau yam dynamic ntawm KEF iQ50s.
