Xyoo, The Dayton Audio B652 tau ploj mus tsis tau rau lub npe ntawm "lub ntiaj teb zoo tshaj qhov nkas las" - tus tsuas hais lus ultra-pheej yig koj tuaj yeem sawv ntsug mloog. Tab sis ib qho tshiab thiab pheej yig dua contender tuaj txog qhov kev sib tw: lub Monoprice MBS-650 (lub tuam txhab kuj muag nws hauv cov khoom ID 8250).

Chaw rau tsheb ciav hlau Kev Tuag Dag
Nyob rau saum npoo, ob qho tib si ntawm cov kab lus tso suab ntsia zoo tib yam. Txhua tus muaj 6.5-inch polypropylene-cone woofer, ib lub tweeter (5/8 inch ntim ntawm Dayton, 1/2 inch), thiab ib daim yas dub, yas hlua yas, 1 ceg siab. Ob qho tib si muaj qhov nyuaj tshaj plaws ntawm kev sib txuas ntawm Crossover - tsuas yog ib tug neeg ua lag luam hauv lub cev nrog cov tweeter kom nws tsis txhob tshuab (crossover tshwm nyob rau hauv lub xeem duab ntawm tsab xov xwm no).
Muaj qee qhov sib txawv, txawm yog. The Dayton tus tweeter yog ua los ntawm txhuas, thaum lub Monoprice txoj haujlwm tau ua los ntawm polypropylene. Cov qub tau tsim lub npov khij lub thawv, thaum kawg tom qab muaj qhov chaw nres tsheb hauv tsheb.
Rau qee qhov, qhov kev sib ntaus sib tua rau "tus khau zoo tshaj plaws" yog zoo ib yam li ob lub ntsej muag sib ntaus sib tua rau ib lub lis piam qub armadillo lub cev. Txawm li cas los xij, koj yuav xav tau ib lub rooj rau chaw nres tsheb ib hnub ib hnub. Thiab yog tias koj kuj yog ib tug neeg txhawb siab, koj yuav tsum thov tus neeg hais lus zoo tshaj plaws rau koj cov nyiaj tsis muaj nqi npaum li cas koj npaj rau kev siv nyiaj.

Muaj ntau ntau tsis txaus siab txog qhov ntawm no, yog tias Monoprice MSB-650 yog pheej yig phau ntawv hais lus. Txawm hais tias lub MBS-650 muaj me ntsis lub pob zeb me me nyob hauv lub nraub qaum uas yuav cia nws mus dai ntawm phab ntsa, peb pom zoo tsis siv nws. Ua li ntawd yuav thaiv qhov chaw nres tsheb ntawm qhov chaw nres tsheb thiab hloov lub suab paj nruag tag nrho ntawm tus neeg hais lus. Tab sis xav tias pheej yig li no tus hais lus yog, nws tsuas muaj peev xwm ntawm lub suab zoo heev. Yog li, yog tias koj xav tau tiag tiag, koj tuaj yeem mus tom ntej thiab thaiv qhov chaw nres nkoj.
Kev xeem pib los ntawm kev sib tsoo hauv MBS-650 lub tso suab sib tham nrog 10 xuab moos ntawm lub suab paj nruag. Tom qab ntawd, txhua qhov MBS-650 tau muab tso rau hauv ib qho 28-inch-siab, cov khoom muag-litter puv npo hlau - kev kho dua zoo dua li nws tau txais, peb paub tseeb - thiab txuas nrog Denon A / V receiver. Peb pom zoo tam sim ntawd hais tias cov neeg hais lus tau zoo heev nrog cov hniav nyiaj hniav kub tawm (grilles tau npuav lub treble me ntsis), yog li ntawd peb tawm ntawm lawv txoj kev rau txoj kev xeem.
Interestingly, lub Monoprice MBS-650 zoo zoo dua nrog nws cov grille tawm dua lub Dayton Audio B652. Tus qub tau lub hnab yas txhuam hniav ncig nws lub woofer, thaum lub sijhawm tom kawg tus woofer yog siv hluav taws xob ua npuas dej.

Kev ua tau zoo
Peb ncaws tawm ntawm kev tshawb xyuas ntawm Monoprice MBS-650 casually; peb xav tau los tsim tej yam kev hais lus saib Ob Tus Txivneej hauv Amazon Instant Video , thiab cov Monoprices tau pov thawj yooj yim.
Tsis tau hais tias peb yeej loj heev txog kev ntsuam xyuas tus neeg hais lus hmo ntawd, tab sis peb pom tias nws yooj yim heev rau lub suab thiab nkag mus rau hauv cov yeeb yam uas tsis cuam tshuam los ntawm MBS-650 qhov kev ua tau zoo. Lub suab tag nrho yog zoo zoo nkauj, nrog tsuas nkag pom khoob khoob khoob khoob khoob khoob khawm "boxy" - nws sounded zoo li lub suab tau bouncing ib ncig nyob rau hauv cov lus qhia enclosure me ntsis, txawm tias nws muaj ib co poly fiber stuffing hauv.
Peb hnov tib co tonal coloration thaum ua si ntawm Holly Cole's version ntawm "Train Song," los ntawm peb txoj kev tso suab hauv 10 lub tso suab . Tab sis tag nrho, lub suab tseem zoo tiag tiag rau tsuas yog $ 30 - yam tsawg kawg li zoo li peb tau hnov los ntawm tus neeg hais lus muaj nyob rau hauv ntau lub tsev-theatre-in-a-box systems. Cole lub suab ua suab nrov zoo nkaus li txhua yam, nrog ib txoj kab ntawm raspiness nyob rau nruab nrab / qis dua treble ntawm nws lub suab (ntawm 2 kHz los yog li ntawd). Lub ntsab bass thaj tsam tob tob uas pib lub suab nrov zoo kawg nkaus thiab tsis meej . Tsis yog super-nruj, thiab tsis heev muaj zog hauv cov ntawv sau qis tshaj, tab sis ib txoj kev ntev ntev ntawm boomy thiab undefined. Lub tso suab duab yog qhov ua tau zoo rau cov nqi. Peb tau muaj peev xwm kom meej meej tawm txhua yam ntawm cov khoom siv hauv cov cuab yeej los ntawm qhov chaw hauv qhov chaw ntawm cov neeg tham.
Peb xav tsis thoob los mloog tau hais tias cov ntaub ntawv txog James Taylor qhov "Ntxoo rau Cov Neeg" los ntawm Nyob ntawm Beacon Theatre - ib qho ntawm cov lus tshaj tawm suab ntawm peb tau pom - zoo heev, tsis muaj kev cuam tshuam ntawm ploj nyob hauv qab ntawm Taylor lub suab . Tsuas muaj kev sib tham ntawm sib sib zog, tab sis txawm tias ntau tus $ 1,000 / tus khub neeg tham tau sib sib zog ua ke sib law lias .
Lub treeb ntawm Monoprice MBS-650 yog me ntsis coarse-sounding, tab sis. Nyob rau ntawm Holly Cole track, lub shakers / maracas tsis nyuaj zoo li cov thawv yas uas muaj cov BBs dua li cov seev cev tiag. Ob lub octaves ntawm treble, los ntawm 5 mus rau 20 kHz, seemed me ntsis tsis, uas txo qhov kev nkag siab ntawm qhov chaw thiab "cua."
Thaum peb tau ntsib nrog Toto's "Rosanna," peb puas tau pom tias MBS-650 tsim ib lub suab blaring thaum nws tau nrov; lub woofer zoo li pib compressing ua ntej tweeter tau ua. Txawm hais tias tus ntses bass thaj tsam kuj thinned heev thaum peb cranked li Mötley Crüe tus "Kickstart kuv lub plawv," peb tau txais lub MBS-650 mus txog 103 dBC ntawm 1 'meter' nrog tsis muaj audible nkag siab.
Yog li cas lub MBS-650 sib piv rau lub Dayton Suab B652? Cov B652 muaj lub suab loj, ntau lub hnab ntim. Txawm li cas los xij, rau peb nws suab coarser nyob rau hauv nruab nrab thiab treble nruab nrab, muab lub suab ib qho kev tsis txaus siab edginess. Thiab cov Dayton suab B652 cias tsis yog kev ntxim nyiam mloog.

Peb ntsuas cov lus teb ntawm lub MBS-650 uas siv cov txheej txheem quasi-anechoic, nrog rau tus neeg hais lus ntawm qhov siab 2-meter-siab thiab ntsuas microphone ntawm 1 meter tawm, siv qhov muaj nuj nqi loj rau ntawm Clio 10 FW suab analyzer los tua tawm cov teebmeem ntawm cov khoom uas nyob ib puag ncig. Bass qhov kev ntsuas tau raug ntsuas los ntawm kev sib ze ntawm lub woofer thiab qhov chaw nres nkoj, ua kom pom qhov chaw nres nkoj thiab teb nws nrog cov lus teb woofer, tom qab ntawd ces qhov ua rau cov lus txiav nplua-anechoic ntawm 215 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. Cov qhab nees tau muab tso rau 1 / 12th octave.
Qhov no yog qhov ntsuas me me rau cov lus teb rau cov lus hais lus tsis txaus ntseeg, tshwj xeeb tshaj yog ib qho uas tsis muaj dab tsi ntau dua li ib tus neeg ua haujlwm hauv lub cev raws li qhov kev nkag mus. Qhov nruab nrab tsuas yog ib qho me me xwb, khi rau ntawm 1.3 kHz, thiab muaj me ntsis nce zog ntawm 3.5 thiab 7.5 kHz - ob qho tib si yog qhov chaw ntawm lub roughness peb tau hnov hauv vocals. Cov lus teb tawm ntawm sab nraud yog qhov zoo heev, tsuas yog muaj kev sib tw khiav tawm ntawm treble thaum koj tsiv mus rau 30 degrees tawm ntawm-axis.
Qhov ntsuas no tau tsis muaj qhov ci. Lub pob txha muaj tsuas muaj cov nyhuv me, tsuas yog txo cov zis ntawm 3 thiab 5.5 kHz los ntawm qhov nruab nrab ntawm -2 dB.
Impedance thiab rhiab heev ob leeg, yog li cov amp nrog tsawg kawg 10 watts los yog li ib tus channel yuav tsum tau tsav cov lus no kom haum siab theem uas tsis muaj teeb meem.

Kev ntsuas thiab Dayton B652
Ntawm no yog qhov ntsuas koj xav xav pom tiag tiag: lub Monoprice MBS-650 (kab xiav xiav) thiab cov Dayton Suab B652 (liab kab), ob qhov ntsuas ntawm 0 degrees hauv-axis. Tsab ntawv zoo li ob lo lus teb zoo li, tab sis Monoprice qhov lus teb yog ib qho me ntsis smoother thiab Dayton B652 muaj ntxim nyiam ntxaum bass teb, nrog ib -3 dB point ntawm 77 Hz thiab 106 Hz rau Monoprice.
Paub tseeb, cov kev ntsuam xyuas ntses bass thaj tsam tsis zoo ib yam nkaus li qhov tau txais B652 tus ntim qhov chaw kaw thiab MBS-650 lub chaw nres nkoj. Thaum peb pom qhov no, peb soj ntsuam cov chaw nyob ntawm Clio, rov qab cov kev ntsuam xyuas bass, thiab tom qab ntawd paub meej tias lawv nrog cov av dav hlau ntsuas. Txhua yam yog qhov tseeb.
