Sekuyiminyaka, i-Dayton Audio B652 yayingakaze ichazwe ngesihloko esithi "isikhulumi segalaji esiphezulu sezwe" - isikhulumi esincane esineshibhile ongakwazi ukuma ukulalela. Kodwa umncintiswano omusha futhi oshibhile ufike ukubhekana nale nselele: i-Monoprice MBS-650 (le nkampani iyayithengisa ngaphansi komkhiqizo ID 8250).

Isigungu Somlomo Wegagasi Yokufa
Phezulu, kokubili amasethi wezikhulumi ze-stereo abukeka cishe ngokufanayo. Ngamunye une-woofer engu-6.5-intshi ye-polypropylene-cone, i-tweeter encane (ama-intshi angu-5/8 ku-Dayton, i-1/2-inch intshi ku-Monoprice), nesigxobo esimnyama, esihlanganiswe nge-vinyl mayelana no-1 onyawo oluphakeme. Bobabili bane-crossover elula kakhulu engenzeka - isisombululo esisodwa esichungechungeni ne-tweeter ukuze igcine ingabi (i-crossover ekhonjiswe esithombeni sokugcina salesi sihloko).
Kodwa kukhona ukungafani, noma kunjalo. I-tweeter ye-Dayton yenziwe nge-aluminium, kuyilapho i-Monoprice ibonakala yenziwe nge-polypropylene. Owokuqala unomklamo webhokisi ovalwe, kuyilapho lesi sici sibonisa i-port yangemuva.
Kwabanye, impi ye "isikhulumi esiphezulu segalaji" isifana ncamashi nemigodi emibili ye-feral elwa ne-armadillo ye-week-old carcass. Kungakhathaliseki ukuthi, uzodinga ilanga lesikhulumi sesigaraji. Futhi uma ungumuntu othakazelisayo womsindo, uzohlala ufuna isikhulumi esiphezulu ngemali yakho kungakhathaliseki ukuthi uhlela kangakanani imali.

Izici nokusetha
• I-woofer yama-poly-6.5 yama-poly
• I-tweeter ye-poly-dome engu-0.5 intshi
• I-Spring-clip isikhulumi sekhebula ukubopha okuthunyelwe
• Ukulinganisa 11.9 x 8.1 x 6.4 ku / 302 x 206 x 163 mm (hwd)
• Isisindo 7.2 lbs./3.6 kg
Akukho okuningi okumele ujabule ngakho, ngoba iMonoprice MSB-650 isisitatimende esincane esishibhile. Nakuba i-MBS-650 inesibindi esincane se-keyhole ngemuva esizoyivumela ukuba ixhome odongeni, sincoma ukuthi singayisebenzisi. Ukwenza kanjalo kuzovimbela i-port yangemuva bese ushintshe umsindo jikelele wesipikha. Kodwa ucabangela indlela engabizi ngayo lesi sikhulumi, ikwazi kuphela ikhwalithi yomsindo omkhulu. Ngakho uma udinga ngempela, ungaqhubeka futhi uvimbele ichweba.
Ukuhlola kuqale ngokuphula izipikha ze-MBS-650 ze-stereo ezinamahora angu-10 omsindo we-pink. Khona-ke, yi-MBS-650 ngayinye yafakwa ngaphansi kwe- stand -inch-high- speaker-stand -litter-filled- speaker-stand- treatment - ukwelashwa kangcono kakhulu kunalokho okuvame ukutholwa, siqinisekile-futhi sixhunywe ku-receiver ye-Denon A / V. Saphawule masinyane ukuthi izikhulumi zizwakala kahle ngama-grilles off (ama-grilles angancipha ukuhamba kancane), ngakho sawashiya ngaleyo ndlela yonke ukuhlolwa.
Ngokuthakazelisayo, i-MBP-650 ye-Monoprice ibheka kangcono nge-grille yayo ngaphandle kwe-Dayton Audio B652. Owokuqala unamapulangwe epulasitiki azungeze i-woofer yayo, kuyilapho i-woofer yesikhombisi igcwele i-gasket gasket.

Ukusebenza
Sichitha ukuhlolwa kweMonoprice MBS-650 ngokuzenzekelayo; kwakudingeka sikhethe uhlobo oluthile lwezikhulumi ukuze sibuke i-Double Double ku- Amazon Instant Video , futhi iMonoprices yafakaza kahle.
Akukhona ukuthi sasinzulu kakhulu ngokuhlola isikhulumi ngalobobusuku, kodwa sibonile ukuthi kulula kanjani ukujabulela umsindo futhi ungene ku-movie ngaphandle kokuphazanyiswa ukusebenza kwe-MBS-650. Ukuzwakala komsindo kwakuhle kakhulu, okuwukuphela kwephutha elibonakalayo elibonakalayo eliwumbala "we-boxy" - kwazwakala sengathi amazwi ayegubha phakathi kwesikhulumi esivumelwaneni kancane, yize yayinezintambo ezinamafutha ngaphakathi ngaphakathi.
Sizwile imibala efanayo ye-tonal lapho sidlala inguqulo kaHolly Cole ethi "I-Train Song," kusukela kumathrekhi ethu ayizintandokazi eziyi-stereo eziyi-10 . Kodwa ngokugcwele, umsindo wawusenhle ngempela ku-$ 30 kuphela - okungenani kuhle njengoba sesizwile kunoma yisiphi isikhulumi sasihlanganiswe ezinkambisweni eziningi zasendlini-in-a-box. Izwi likaCole lalizwakala kahle ngokusheleleka, ngokulandela okuncane nje kwe-raspiness emkhatsini we-midrange / ophansi wezwi lakhe (cishe 2 kHz noma ngaphezulu). Ama-bottom bass amanothi aqala ukuhlabelela okuzwakalayo okucacile okucacile futhi okungaqondakali . Akuyona into eqinile kakhulu, futhi ayinamandla kakhulu kumanothi aphansi kunazo zonke, kodwa izindlela ezide ezivela ku-boomy futhi ezingachaziwe. I-imaging stereo empeleni iyamangalisa ngentengo. Sakwazi ukucacisa ngokucacile izinsimbi zomculo ngamunye wezingoma zomculo ezisezingeni eliphakathi kwesikhulumi.
Sashaqeka lapho sizwa ukuthi ukuqoshwa kukaJacob Taylor "Ukugubha Abantu" kusukela ku- Live eBeacon Theater - enye yezinkinga zokukhiqiza ngokuzwakalayo okunamandla kakhulu esikutholile - zizwakala kahle kakhulu, zingekho ukulandelela phansi kwezwi likaTaylor . Kukhona nje ukuthinta kwe-sibilance, kodwa ngisho nezikhulu eziningi ze-$ 1,000 / izipikha ezimbili zingazwakala zihambisana nalesi ithrekhi.
Nokho, ukuhamba kweMonoprice MBS-650 kwakunzima kakhulu. Emthonjeni weHolly Cole, abakwa-shakers / maracas babezwakala kakhulu njengamabhokisi aseplastiki agcwele ama-BBs kunjengezinsimbi zangempela. Ama-octaves amabili aphezulu e-treble, kusuka ku-5 kuya ku-20 kHz, ayebonakala engenalutho, okwehlisa umqondo wesikhala "nomoya."
Uma sithinteka nge-"Rosanna" kaToto, saqaphela ukuthi i-MBS-650 iqala ukukhala umsindo lapho ikhala; i-woofer ibonakala iqala ukucindezela ngaphambi kokuba i-tweeter iyenze. Nakuba ama-bass abuye aphule kakhulu lapho sishaya i-"Kickstart My Heart" yaseMötley Crüe, sakwazi ukuthola i-MBS-650 kuze kube ngu-103 dBC kumamitha angu-1 ngaphandle kokuphazanyiswa kalula.
Ngakho i-MBS-650 iqhathanisa kanjani ne-Dayton Audio B652? I-B652 inomsindo omkhulu, okhudlwana. Noma kunjalo, kithi sasizwakala sineqhaza eliphakathi kwe-midrange ne-treble, sinikeza amazwi ubuhle obungamukeleki. Futhi i-Dayton Audio B652 imane yayingeyona emnandi ukuyilalela.

Izinyathelo
Impendulo yephindaphindiwe
I-on-axis: ± 4.3 dB kusuka ku-106 Hz kuya ku-20 kHz
Isilinganiso: ± 3.7 dB kusuka ku-106 Hz kuya ku-20 kHz
Impedance
I-7.4 ohms / 350 Hz / -1 °, okungenani i-9 ohms
Ukuzwela (2.83 volts / 1 imitha, anechoic)
87.7 dB
Silinganise impendulo yemvamisa ye-MBS-650 usebenzisa inqubo ye-quasi-anechoic, isikhulumi sisezingeni eliphakeme lamamitha angu-2 kanye nomakrofoni wokulinganisa kumamitha angu-1 kude, usebenzisa umsebenzi wokuqhafaza kumcwaningi womsindo we-Clio 10 FW ukuqeda imiphumela ye-acoustical yezinto ezizungezile. Impendulo ye-Bass yayilinganiswa ngokuvala ama-woofer ne-port, ukukala ukuphendula kwe-port futhi ukuyifakela impendulo ye-woofer, bese ubeka umphumela emigqeni ye-quasi-anechoic ku-215 Hz. I-trace eluhlaza okwesibhakabhaka eshadini ngenhla ibonisa impendulo yemvamisa ku-axis; i-trace eluhlaza ibonisa isilinganiso sezimpendulo ku-0, ± 15, no-± 30 degrees ngokulinganayo. Imiphumela yalungiswa ku-1/12 octave.
Lesi yisilinganiso sokuphendula imvamisa esiphuthumayo ngesiphakamiso esingabizi kakhulu, ikakhulukazi esingenalutho olungaphezu kwekhanda elilodwa njenge-crossover. Amaphakathi ahamba kahle ngaphandle kwesibalo esincane, esibanzi esiphezulu ku-1.3 kHz, futhi kunyuke kancane kwamandla phakathi kuka-3.5 no-7.5 kHz - kokubili okungaba umthombo we-roughness ngezinye izikhathi esiwazwile ngamazwi. Impendulo ye-off-axis inhle kakhulu, ne-rollout yokuhamba kancane kancane lapho uhambisa ama-degrees angu-30 oku-off axis.
Lesi silinganiso sithathwe ngaphandle kwegrile. I-grille inomphumela omncane kuphela, ikakhulukazi ukunciphisa okukhipha phakathi kuka-3 no-5.5 kHz ngokwesilinganiso se--2 dB.
Ukuphelelwa yisikhathi nokuzwela kokubili kuphezulu, ngakho-ke noma yikuphi okungenani okungenani ama-watts angu-10 noma isiteshi ngasinye kufanele sikwazi ukushayela lesi sikhulumi emazingeni aphakeme angenayo inkinga.

Izinga vs. Dayton B652
Nansi isilinganiso owafisa ukusibona: i-Monoprice MBS-650 (i-trace blue) vs. Dayton Audio B652 (ukulandelela obomvu), kokubili kulinganiswa nge-0 degrees kwi-axis. Qaphela ukuthi izimpendulo ezimbili zifana kanjani, nakuba impendulo kaMonoprice ilula kancane futhi i-Dayton B652 inempendulo ejulile kakhulu, ne -3 dB iphuzu lika-77 Hz no-106 Hz le-Monoprice.
Ngokuqinisekile, izilinganiso zokuphendula ezisezingeni eliphansi azibukeli njengokulindelekile okunikeziwe okuqinisekisiwe kwe-B652 kanye ne-MBS-650's ported enclosure. Lapho sibonile lokhu, sihlole izilungiselelo ku-Clio, siphindaphinda izilinganiso ze-bass, bese sibaqinisekisa ngezilinganiso zezindiza zomhlaba. Konke kulungile.

Thatha okokugcina
Kithina, i-Monoprice iphumelela ngoba izwakala ilula ehamba phambili. Abanye bangathanda i-Dayton B652 kangcono kangcono ukuphendula kwayo okujulile nokuzwakala okuzwakalayo. Kodwa uma ufuna ukulungiswa kwe-sonic - noma okungenani oseduze uzothola lokho ku-$ 30 - i-Monoprice MBS-650 iyoba ngcono kangcono imali yakho.
