Skinny = Tsis muaj zog?
Puas yog ua tau los thov kom muaj suab paj nruag loj thiab cov neeg mloog me me? Yog, tab sis nws tsis tshua muaj. Nco ntsoov, George Benson suab zoo li hu nkauj "Muab Kuv Hmo" raws li nws ua si "Willow Weep rau kuv." Tiam sis kev ua yeeb yam los ntawm cov yeeb yaj kiab nyiam Rod Stewart thiab Barry Manilow los kho cov kev cai tsis tau txais kev qhuas los ntawm cov nyiam tshaj plaws ntawm Great American Songbook.
Saib Suab hauv kev ua haujlwm nrog nws cov kev hloov tshiab tsis ntev los no ntawm nws cov kab xev. Sojntsuam cov nyiaj tau los ntawm cov neeg ua suab quas zoo rau cov neeg ua haujlwm zoo, cov suab lus zoo, tab sis tus kab Radius yog lub tswv yim tsim ua rau cov chav pw thiab cov chav xov xwm me.
Kom cov suab zoo ntawm Radius cov neeg tham, Saib xyuas qiv nyiaj tsim rau nws cov kab ntau dua. Cov no muaj xws li lub tuam txhab C-CAM (ceramic-coated aluminium / magnesium) diaphragm khoom nyob rau hauv woofers thiab tweeter. Cov txheej txheem ceramic pab daws cov resonances hauv cov hlau, ua rau cov tsav tsheb ua haujlwm zoo ib yam li txhav pistons tsis ywj pheej nruas hau. Ib yam li nyob rau hauv lub tuam txhab cov tuam txhab ntau tus neeg hais lus ntau, cov tsav tsheb yog ciav hlau los ntawm lub tsheb kom pab txhav cov ntaub thaiv (saib daim duab tom qab ntawm nplooj ntawv kawg ntawm kev txheeb xyuas no). Cov chaw nres nkoj muaj rifled, xws li rab phom chim, rau cua cua ua kom haum.
Tus $ 1,249 / pair Radius 270 ntauwd hais lus nyob rau sab saum toj ntawm txoj kev hloov kho Radius. Muab Radius 270 tus 50 Hz ntses bass thaj tsam ntxiv, koj tuaj yeem siv nws ntawm nws tus kheej hauv lub tso suab thaum koj tsis mus nrhiav kev sib tw lossis sib sib zog nqus. Yog tias koj xav ntxiv ntau tshaj bass los yog nqaij tawm ntawm 270s mus rau hauv ib chav tsev ua yeeb yam suab paj nruag lub suab, Saib Suab muaj ib qho array ntawm Radius tham thiab subwoofers uas yuav tsum ua tus ua kom yuam kev.
Nws nyuaj rau qhov tsis kam lees qhov Radius 270 pom qhov tsis txaus siab, tab sis koj tau pom zoo tias kev ua suab nrov zoo li cas thaum koj tau txais ib daim ntawv tshaj li 5 nti dav dav, ntim nrog ob tug 4-nti woofers. Cia wb mloog ...

Tus 270 yog ib qho yooj yim, muaj kuab me me hais lus uas tawm hauv lub thawv tuaj txhij txhua. Muaj tsis ntau rau lub teeb. Kuv muab tso rau hauv qhov chaw kwv yees qub uas kuv muab tso rau feem ntau cov neeg tham; nyob rau hauv rooj plaub no tus nraub qaum ntawm cov yees zaum 28 nti ntawm phab ntsa tom qab lawv, thiab kuv toed ob leeg rau hauv ntsej muag ncaj ntawm kuv lub rooj zaum mloog.
Kuv txuas rau ob qho tib si rau Denon A / V receiver. Qee lub sij hawm kuv tau khiav lawv txhua yam, thiab qee zaus kuv siv lawv nrog SVS SB-2000 subwoofer , hla lub Radius 270 mus rau subwoofer ntawm 80 Hz.

Saib Suab Radius 270: Kev Ua Tau
Thaum kuv tau ua ntau zaus thaum kuv pib rov qab tham ib tus neeg hais lus, kuv cia li pleev nrog lub Radius 270, ua si hauv cov ntawv Jazz sau kuv tus phooj ywg Nick qiv kuv. Nws tsis tau mloog lawv txog li ib xyoo caum xyoo, tiam sis lawv ua rau cov neeg txuam tshwj xeeb - tsis muaj ib tug tau qis tshaj plaws. Tsis tau lwm qhov laj thawj zoo los ua tus tig npau taws: Koj tuaj yeem ceev cov ntawv koj cov phooj ywg uas tsis muaj turntables.
Kuv lub pob ntseg tau thim sai sai thaum kuv tau hnov qhov super-dav, lub suab nrov ntawm Radius 270 txawb tawm ntawm guitarist Gabor Szabo's Lub Sorcerer , xyoo 1967 tau sau tseg nyob hauv Jazz Workshop hauv Boston. Szabo's twangy guitar (hlau-hlua, sab-sab saum toj acoustic nrog ib leeg-coil pickup) thiab tus tub ceev xwm Marty Morrell lub tsaj thiab cov suab paj nruag ua suab nrov zoo li lawv tau nchuav tawm cov phab ntsa tawv ntawm ib lub chaw ua si nruab nrab. Kuv nyiam txoj kev uas tus Radius 270 ua rau kuv rov mus ua dua qhov kev lom zem ntawm lub venue kom zoo li ntawd. Raws li qhov kev tshawb nrhiav tom qab tau qhia rau kuv, Jazz Workshop yog ib qho chaw zoo me me, qhov zoo li lub Vanguard lossis Me Lub nroog New York City, yog li pom tias Radius 270 tau txais txoj cai.
Drummer Chico Hamilton tus txiv neej los ntawm Ob Worlds (kuj featuring Szabo) zoo tshaj, nrog saxist / flautist Charles Lloyd lub suab sib sib zog nqus zoo li emanate los ntawm ib qhov chaw loj virtual nyob rau pem hauv ntej ntawm kuv chav es uas los ntawm Radius 270s.
Cov ntaub ntawv qub hauv jazz, tab sis, tsis yog cov khoom siv ntau tshaj plaws, yog li kuv hloov mus rau kuv qhov kev sib tw 10 nyiam tso suab . Tam sim no tus Dan's "Aja" (ib qho tsis yog kuv thawj 10 hnub no, tab sis mas nws yog hauv kuv qhov siab tshaj plaws 15) muaj suab nrov heev, nrog rau kev sib deev los rau cov me nyuam loj hauv cov ntaub ntawv uas tsis muaj qhov cim tseg ntawm kev nyuaj siab feem ntau hais lus rau nws. Lub 270s kho Donald Fagen lub suab reedy li kom zoo zoo.
Kuv puas tau paub tias thaum Chuck Rainey tus ntses bass thaj suab nrawm, nws tsis suab haib, thiab piano lacked qee lub cev. Kuv kuj pom cov ntawv hu ua cymbals ua rau pom me ntsis ntawm qhov tseem ceeb hauv nruab nrab-treble, tiam sis tsis ntau npaum li qhia nyob rau hauv lub thauv treble, saum 10 kHz. Qhov no ua rau kuv xav paub yog tias tej zaum Saib Suab cov engineers rho tawm ntawm treble me ntsis kom zoo tshuav me ntsis woofers 'sib tw tsim tawm. Tias yuav yog ib tug khiav tawm tsiv, kuv xav tias - qee zaum ib lub tweeter nrog lus teb rau 20 kHz suab yoojyim thaum uas paired nrog cov me woofers.
Kuv nyiam "khiav suab paj nruag" khiav, Toto's "Rosanna," hnov zoo loj heev los ntawm Radius 270, nrog rau lub suab nrov, reverberant suab kuv xav txog pab pawg neeg tau mus. ('Ua rau koj paub txhua leej txhua tus rov qab thaum 1980s tau mus rau lub suab ntawd.) Thaum kuv thawb ntim dhau 92 dBC, ntsuas los ntawm kuv lub rooj mloog 11 ko taw tseg, lub suab tau txais nyias thiab tus kick nruas poob nws kick. Nyob rau Mötley Crüe's "Kickstart Kuv Lub Plawv," lub Radius 270 tsuas yog blared ntawm kuv thaum kuv sim cranking nws mus rau satisfying qib tab sis muab lub SB-2000 subwoofer rau hauv qhov system tsau qhov teeb meem no kiag li thiab kiag li.
Kuv nyiam qhov dab Radius 270 tau ua nrog cov suab nrov; txhua txhua tus singer kuv ua si los ntawm nws sounded du, uas tsis muaj sib ceg notilance los yog midrange coloration. Kuv tau nco ntsoov tias, ntawm James Taylor cov ntaub ntawv txog "Cov Neeg Ua Dua" los ntawm Nyob Hauv Lub Tsev Kawm Ntawv Beacon, Taylor lub suab nrov nrov me ntsis hauv cov ntawv sau qhia tob tshaj plaws. Li ntawd Reverend Dennis Kamakahi rau nws cov ntaub ntawv ntawm "Ulili'E." Kuv guessed qhov no yog ib qho cwj pwm ntawm me ntsis bass thawv Kuv xav saib cov engineers ntxiv los muab 270 tus tonal tshuav ib qho ntxiv heft. Hloov cov subwoofer rov qab, thiab yog li liming frequencies hauv qab 80 Hz tawm ntawm 270, coj cov lus qis dua rov qab mus rau lub cheeb tsam ntawm kev muaj tiag.

Kuv ntsuas cov lus teb ntawm Radius 270 siv cov txheej txheem quasi-anechoic, nrog rau tus neeg hais lus ntawm tus 28-nti (67 cm) thiab ntsuas microphone ntawm 1 meter, siv qhov ua haujlwm ntawm kuv tus Clio 10 FW suab analyzer los tua tus acoustical teebmeem ntawm cov khoom ib puag ncig. Bass teb tau ntsuas los ntawm kev siv cov dav hlau hauv av, nrog lub microphone rau hauv av 1 meter ntawm cov lus hais, ces muab qhov kawg rau cov curasi-anechoic ntawm 250 Hz. Cov kab xiav nyob rau hauv daim duab saum toj no qhia txog qhov nquag teb rau ntawm-axis; cov kab ntsuab qhia qhov nruab nrab ntawm cov lus teb ntawm 0, ± 15 thiab 30 degrees horizontally.
