Kev Tshawb Fawb Txog Hnub Tuaj Tshaj Tawm Hauv Lub Khoos Tshaj Tshaj Tawm
Lub Wirecutter nyuam qhuav tau thov kom kuv ua qhov kev ntsuam xyuas ntau ntawm powered, 2.0-channel speaker systems tsim rau desktop / computer audio. Hauv qhov kev xeem, kuv thiab ib lub vaj huam sib luag ntawm cov neeg nyeem tau muab piv rau ntau yim qauv; muaj peb ntxiv kuv tshem tawm vim kuv xav tias lawv tau xoom caij nyoog uas tau khaws raws li qhov zoo tshaj plaws, qhov thib ob los yog qhov thib plaub zoo tshaj plaws. Thiab ntawm Lub Wirecutter, thaum koj nyob nraum dhau plaub-zoo dua, koj tawm ntawm kev khiav.
Muaj ntau lub tshuab hauv kuv lub tsev, kuv tsis tuaj yeem muab lawv tso rau ntawm qhov ntsuas kuv thiab pom lawv ua li cas hauv kev sim (lab).
Kuv ntsuas cov lus teb txhua zaus, uas yuav qhia tau koj ib qho kev qhia zoo txog qhov ua tau zoo npaum li cas. Qhov zoo tshaj plaws, qhov lus teb ntawm cov kab xiav rau hauv txhua daim duab (uas sib sau ua ke ntawm kev ntsuas ntawm 0 degrees, ncaj qha ntawm tus neeg hais lus), yuav tsum tau sib tiaj los yog ze rau nws. Thiab hom phiaj, qhov cim tseg hauv cov duab cim (uas qhia qhov nruab nrab ntawm cov lus teb ntawm 0, ± 10, ± 20 thiab 30 degrees horizontally) yuav yog me ntsis downturned ntawm sab xis ntawm daim duab, vim tias qhov kev ntsuam xyuas zaus nce 20 kilohertz, uas yog feem ntau txais theoretical txwv ntawm tib neeg lub rooj sib hais.
Kuv ua cov kev ntsuam xyuas no uas siv cov khoom siv quasi-anechoic, nrog rau tus neeg hais lus ntawm qhov 2-meter-siab siab thiab MIC-01 ntsuas microphone ntawm 1 meter, siv qhov ua haujlwm ntawm kuv tus Clio 10 FW suab ntsuas los tua cov teebmeem ntawm lwm tus khoom. Kuv hloov lub siab qhov ntawm qhov siab, nyob rau hauv qhov laj thawj, kom tau txais qhov lus teb zoo los ntawm txhua tus neeg hais lus. Bass lo lus teb tau ntsuas raws li siv cov dav hlau hauv av, nrog lub microphone rau hauv av 1 meter ntawm cov neeg hais lus, ces muab qhov teeb meem rau cov curasi-anechoic curves qhov chaw ntawm 160 thiab 180 Hz. Quasi-anechoic cov ntsiab lus tau muab tso rau 1 / 12th octave, lub dav hlau hauv pem teb tau los ntawm 1 / 6th octave. Cov qhab nias tau raug ua rau 0 dB ntawm 1 kHz.
Incidentally, thaum kuv xam cov naj npawb ntxiv / rho tawm dB, kuv muab txhua yam hauv qab 200 Hz tshem tawm vim hais tias qhov scaling ntawm tus ntses bass teb rau cov lus teb quasi-anechoic vam khom rau qee qhov kev kawm ntawm kev sib tw. Kuv xam cov bass response limit los ntawm kev siv cov zis tawm ze tshaj 200 Hz thiab rho tawm -6 dB.

Kev ntsuas A2 kev ntsuas
Teb zaus
On-axis (xiav): ± 3.3 dB los ntawm 82 Hz rau 20 kHz
Nruab Nrab (ntsuab): ± 2.4 dB los ntawm 82 Hz rau 20 kHz
Txawm hais tias lub A2 + muaj hump ntau nyob rau hauv cov kab bass thaj tsam ib ncig 140 Hz, cov lus teb tag nrho yog admirably tiaj tus. Vim tias kuv normalize txhua yam rau 0 dB ntawm 1 kHz, nws zoo li lub A2 + muaj ib qho kom siab midrange thiab treble teb, tab sis tiag tiag li nws muaj yog ib nrab ntawm cov roughly -3 dB ntawm 400 Hz thiab 1.5 kHz nruab nrab midrange.

Kev ntsuas bass ntsuas ntawm lub Khub 20 mus tiag tiag tob - tab sis qhov kev ntsuas no nyob rau theem qis, yog li tsis txhob cia siab tias bass zog los ntawm cov lus no. Qhov lus teb tam sim no zoo nkaus li zoo nkauj ragged. Li niaj zaus, Bose tsis qhia cov tsav tsheb hauv nws cov khoom lag luam, tab sis qhov no zoo nkaus li kev qhia ntawm kev qhia tawm ntawm ib tus tib neeg tsav tsheb.

Nruab Nrab (ntsuab): ± 4.5 dB ntawm 57 Hz rau 20 kHz
Ntawm no yog tus hais lus uas ntsuas tau zoo li nws tau suab rau kuv. Thaum cov lus teb noj cov lus teb yuav ua rau kev sib sib zog nqus heev (ua tsaug rau nws cov pa tawm ob tog), thiab qhov nruab nrab yog qhov qhwv, qhov siab teb saum toj no 3 kHz yog dab tsi ua rau tus neeg hais lus no "suab paj nruag" uas kuv tau hais hauv qhov kev xeem.

Tam sim no peb nyob nraum hais lus. Tus Spinnaker ntsuas txog kev tuag-pav ca xwb. Feem ntau cov neeg hais lus siab tsis ntsuas qhov no. Tau kawg, tus Spinnaker muaj cov teebmeem hauv kev tawm hauv qhov tso cai rau nws ua kom cuag tau zoo li no.
Incidentally, cov neeg hais lus me me zoo li cov xeem ntawm no yuav tsum ntsuas thaj vim hais tias cov broad dispersion ntawm lub me woofers yuav muab zoo dua nrog cov tweeters. Yog vim li cas lawv thiaj tsis ntsuas kev ncaj nraim yog cov engineers lawv tsis muaj nyiaj txaus los muab cov kev sib txuas lus hauv kev sib txuas lus hauv kev hais lus, lossis kab tias qee zaus lawv tsis ua tiag tiag los tsis ua muaj lub sij hawm los yeej ntsia hlau. Nrog Spinnaker nws yooj yim txawm tias nws yog ib txoj kev tsim peb-txoj kev nrog 3/4 inch tweeter, ib nrab ntawm 2-3 / 4-inch thiab 4-inch woofer.
