Kwaphela iminyaka, i-Dayton Audio B652 yayingenakunikwa isicatshulwa esithi "isithethi segalaji esona sikhulu sehlabathi" -isisithethi esisodwa esincinci esinqabileyo ongakwazi ukuma ukuphulaphula. Kodwa umqhubi omtsha kwaye ongenanciphisa ufikelele ekujongeni umngeni: i-Monoprice MBS-650 (le nkampani iyithengisa phantsi kwe-ID ye-ID engu-8250).

Umlomo weGarage Somlomo wokufa
Emhlabeni, zombini iiseti zeentetho ze stereo zibukeka zifana ngokufanayo. Ngamnye unesipopu se-polypropylene-cones ye-6.5-intshi, i-tweeter encinci (intsuku ye-5/8 kwi-Dayton, i-1/2-intshi intshi eMonoprice), kunye ne-black, i-vinyl ehlanganiswe nge-1 foot high. Bobabini banesigqeba esilula kunokwenzeka sesekethe - nje kuphela i-capacitor kwichungechunge kunye ne-tweeter ukuyigcina ekuvutheni (i-crossover eboniswe kumfanekiso wokugqibela wale nqaku).
Kukho ukungafani, nangona kunjalo. I-tweeter ye-Dayton yenziwe nge-aluminium, ngoxa i-Monoprice ibonakala iyenziwe nge-polypropylene. Ixesha langaphambili linomxholo wokubhankwa kwebhokisi, ngelixa i-final ishicilelwe kwisango elingemuva.
Kweminye, imfazwe "yeyona ngongoma yesigcawu" igqithisa ngokufana neentlobo ezimbini ze-feral zokulwa kwi-carmadi ye-armadillo yeveki. Kungakhathaliseki ukuba, uya kufuneka esinye isithethi segaraji. Kwaye ukuba unomdlali womculo, uya kuhlala ufuna i-sithethi esiphezulu kwimali yakho kungakhathaliseki ukuba uceba kangakanani ukuchitha imali.

Izixhobo kunye nokusekwa
• I-woofer ye-poly-6.5 intshi
• I-0.5-intshi ye-poly dome tweeter
• Isithethi-sikrini sesithethi sekhompyutheni yokubopha
• Imilinganiselo 11.9 x 8.1 x 6.4 kwi / 302 x 206 x 163 mm (hwd)
• Ukulinganisa i-7.2 lbs //3.6 kg
Ayikho into enokuyivuyisa apha, ngokuba i-Monoprice MSB-650 iyisithethi esincinci se-addresshelf. Nangona i-MBS-650 inomnquba omncinci kumqolo oya kukuvumela ukuba uxhomeke eludongeni, sincoma ukuba singayisebenzisi. Ukwenza njalo kuya kuvimba ichwep yangemuva kwaye utshintshe isandi sonke sesithethi. Kodwa ekuqwalaseleni indlela engathengi ngayo esi sithethi, sinokukwazi kuphela umgangatho wezwi. Ngoko ukuba ufuna ngokwenene, unokuqhubeka kwaye uvimbele ichweba.
Ukuvavanya kwaqala ngokuphula ii-stereo ze-MBS-650 ezineeyure ezili-10 zomsindo we-pink. Emva koko, nganye i-MBS-650 yafakwa kwi-inch-high-height-litch-full-tilt-filled- speaker -static-static-static-static-sterey-full-treatment. Sazibona ngokukhawuleza ukuba izithethi zazizwakala kakuhle kunye nezixhobo (i-grilles inokuthi idibanise i-treble), ngoko siye sabashiya ngaloo ndlela ukuze kuhlolwe lonke uvavanyo.
Okuthakazelisayo kukuba, i-Monoprice MBS-650 ibonakala ilungile kunye ne-grille yayo ngaphandle kwe-Dayton Audio B652. I-yangaphambili inomngxuma weplastiki ejikeleze i-woofer yayo, ngelixa i-woofer yeyokugqibela igqitywe nge-gasket ye-foam.

Ukusebenza
Sichitha ukuphicothwa kwe-Monoprice MBS-650 ngokukhawuleza; Sasidinga ukuseta uhlobo oluthile lwezithethi ukuba lubukele i -Double kwi- Amazon Instant Video , kwaye i-Monoprices yabonakala ikulungele.
Akunjalo ukuba sasinzulu ngokwenene ngokuvavanya isithethi ngalobo busuku, kodwa saqaphela ukuba kulula kangakanani ukuvuya kwisandi kwaye ungene kwi-movie ngaphandle kokuphazamiseka ukusebenza kwe-MBS-650. Isandi saso sasilungileyo, kunye nephutha elibonakalayo elibonakalayo nje ngokuba ngumbala we "boxy" - kwakubonakale ngathi amazwi ahlabayo kwi sithethi idibanise encinci, nangona yayinefrayibhile ye-poly fiber ngaphakathi.
Sivile umbala ofanayo wee tonal xa udlala inguqulelo kaHolly Cole ethi "Qeqesha ingoma," kwiindlela zethu ezi- 10 ezizithandayo zokuhlolwa kwe stereo . Kodwa ngokubanzi, isandi sasisilungele i $ 30 kuphela - ubuncinane njengoko sivile kuso nasiphi na isithethi esabandakanywa kwiinkqubo ezininzi ze-home-in-box-box. Izwi likaCole lalizwakala ngokugqithiseleyo, ngokukodwa okufutshane kwintlanzi ephakathi kwe-midrange / ngaphantsi kwezwi lakhe (malunga ne-2 kHz okanye njalo). Amanqaku angqongqo aqala ukuhlawula itywala ecacileyo ngokucacileyo kwaye ingabonakali . Ayinamandla kakhulu, kwaye ayinamandla kakhulu kumanqaku aphantsi kakhulu, kodwa iindawo ezide ezivela kwi-boomy and undefined. Ukucinga ngokubhaliweyo kuyamangalisa ngokwenene. Sakwazi ukucacisa ngokucacileyo nganye yeefayile zomculo zengcingo kwisithuba esicacileyo phakathi kwezithethi.
Sothuswa xa siva ukuba ukurekhoda kukaJames Taylor "Ukugubungela Abantu" bevela kwi- Live kwi-Beacon Theater - enye yeemvavanyo ezivakalayo zokuvelisa izandi esizifumene - zivakala kakuhle, zingabikho nto zokubethwa phantsi kwezwi likaTaylor . Kwakukho nje umnxeba we sibilance, kodwa nangona iincinci ezili-$ 1,000 / iibini zithethi zivakalayo zilalele kulo mzila.
Kodwa ukuhamba kweMonoprice MBS-650 kwakunzima kakhulu, nangona kunjalo. Kwimizila yeHolly Cole, i-shakers / maracas ibonakale ifana neebhokisi zeplastiki ezizaliswe yi-BBs kunokuba zixhobo zangempela. Ama-octaves aphezulu aphezulu, ukusuka kwi-5 ukuya kwi-20 kHz, yabonakala engenanto, eyanciphisa umqondo wendawo kunye "nomoya."
Xa sithinteka kunye noToto "uRosanna," saqaphela ukuba i-MBS-650 ivelisa isandi sokukhwaza xa sikhala; i-woofer yayibonakala iqalisa ukuxineka phambi kwe-tweeter. Nangona iibhasi zazingqongqo kakhulu xa sithintela iMötley Crüe "iKickstart My Heart," sakwazi ukufumana i-MBS-650 ukuya kwi-103 i-DBC kwi-1 imitha engenakuphikiswa ngokulula.
Ngoko i-MBS-650 ithelekisa njani kwi-Dayton Audio B652? I-B652 inesandi esikhulu, esiphezulu. Nangona kunjalo, ngathi kuthiwa i-coarser kwi-midrange ephezulu kwaye ihamba, ibeka ilizwi ingqungquthela engavumelekanga. Kwaye i-Dayton Audio B652 yayingeyona nto imnandi ukuphulaphula.

Imilinganiselo
Ukuphendula ngokuphindaphindiweyo
I-axis: ± 4.3 dB ukusuka kwi-106 Hz ukuya kwi-20 kHz
Umyinge: ± 3.7 dB ukusuka kwi-106 Hz ukuya kwi-20 kHz
Ukunyamezela
Ubuncinane 7.4 ohms / 350 Hz / -1 °, i-9 ohms ekhethiweyo
Ubuninzi (2.83 volts / 1 meter, anechoic)
87.7 dB
Silinganise impendulo yempendulo ye-MBS-650 isebenzisa inqubo ye-quasi-anechoic, isithethi sinokuma kwe-2-meter-high kunye nemakrofoni yokulinganisa kwimitha engama-1, usebenzisa umsebenzi wokuqhafaza kwi-Clio 10 FW i-analyzer audio imiphumo ye-acoustical yezinto ezizungezile. Impendulo ye-Bass yayilinganiswa ngokuvala i-wooper kunye ne-port, ukubeka impendulo yesipoti kunye nokuyifakela impendulo ye-woofer, ize igaxe umphumo kwii-quasi-anechoic curves kwi-215 Hz. Inkcazo eluhlaza okwesibhakabhaka kwitshathi elingentla ibonisa impendulo yevama kwi-axis; ulandelelwano oluluhlaza lubonisa umyinge weempendulo kwi-0, ± 15, kunye no-± 30 degrees ngokulinganayo. Iziphumo zahlanjululwa kwi-octave ye-1/12.
Esi sisilinganiselo esiphezulu sempendulo yokuphendula ngesantya esithengiyo, ngokukodwa enye engenanto engaphezulu kombane omnye. Iiphakathi zihamba kakuhle ngaphandle kobukhulu obumnene, obubanzi obujoliswe kwi-1.3 kHz, kwaye kukho ukwanda okukodwa kwamandla phakathi kuka-3.5 no-7.5 kHz-zombini inokubakho umthombo wobunzima esivakalayo ngezinye izikhathi ngezwi. Impendulo ye-off-axis iyinto enhle kakhulu, kunye nokugqithwa kokuhamba ngokukhawuleza njengoko uhamba ukuya kuma-degrees angama-30-axis.
Lo mqathango uthathwe ngaphandle kwegridi. I-grille inefuthe elincinane kuphela, ngokunciphisa ukunciphisa phakathi kwe-3 no-5.5 kHz ngokulinganiselwa malunga ne--2 dB.
Ukunyamezela nokuvaleka kokubili kukuphakamileyo, ngoko ke naluphi na ukukhupha okungenani ama-watts ama-10 okanye ngoko iseshoni ngasinye kufuneka ukwazi ukuqhuba le sithethi kumazinga aphezulu aphezulu ngaphandle kwengxaki.

Imilinganiselo vs. Dayton B652
Nantsi imilinganiselo oyifunayo ngokwenene: i-Monoprice MBS-650 (ulandelelwano oluhlaza okwesibhakabhaka) ngokubhekiselele kwi-Dayton Audio B652 (ulandelelwano obomvu), zombini lilinganiselwa kuma-0 degrees kwi-axis. Phawula indlela ezibukeka ngayo ezimpendulo ezimbini, nangona impendulo kaMonoprice ilula kwaye i-Dayton B652 ineempendulo eziphantsi kakhulu, nge -3 dB iphuzu lika-77 Hz no-106 Hz leMonoprice.
Ngokuqinisekileyo, imilinganiselo yokuphendula isiseko ayiboni njengokuba kulindeleke kunikwa i-B652 yokuvalwa kunye ne-MBS-650's ported enclosure. Xa sibonile oku, sihlolisise izicwangciso kwiCoo, siphinda ngokuphindaphindiweyo iimilinganiselo zee-bass, kwaye siqinisekisile ngeemilinganiselo zomhlaba. Konke kuchanekile.

Gqibela Thatha
Kithina, i-Monoprice iphumelela ngenxa yokuba itywina elula. Abanye banokuthanda i-Dayton B652 engcono kwimpendulo yayo ephantsi kunye nesandi esicacileyo. Kodwa ukuba ufuna ukulungiswa kwee sonic - okanye ubuncinci obusondeleyo uza kufumana i-$ 30 - i-Monoprice MBS-650 iya kuba bhetele imali yakho.
