Uhlelo lweSomlomo Lomhlaba Oyingqikithi Kakhulu
Ingabe leyo ncazelo izwakala i-hyperbolic? Akukona ngempela. Ngasekuqaleni konyaka, kwakukhona umonakalo omkhulu lapho uMonoprice - umdayisi we-intanethi ezinikezele ekuhambiseni imikhiqizo yomsindo kanye nezesekeli ngechungechunge lwamanani abhekene nabathengi - wafaka uhlelo lwesikhulumi esingu-$ 249 5.1 olubonakala lufana ncamashi ne-well- kubukeze uhlelo lwe-$ 395 Energy Take Classic. I-CNet ibuyekeze kokubili izinhlelo futhi ayikho into ephawulekayo yokusebenza phakathi kwabo.
Bese bacela engisebenza naye uGeffrey Morrison ukuba aqhube kancane kancane kulezi zinhlelo ezimbili. Yena naye wangicela ukuba ngigijime amanye ama-lab izilinganiso ezikhulwini ukuze ngibone ukuthi ngabe kukhona yini umehluko. Esihlokweni esilandelayo, sithole umehluko okwanele ukusho ukuthi izikhulumi ezimbili azihambisani ngokufanayo, kepha ukufana okwanele ukuthi zisebenza ngendlela efanayo.
Icala elilandelwe, elixazululwe emibhalweni engaziwa.
Manje uMonoprice usungule uhlelo olusha, ngenombolo yesimodeli 10565. Kubonakala sengathi ifana neyaphambilini ye-9774 system. I-woofer kusikhulumi se-satellisi ichithe uthuli lwesikhumba, esikhundleni se-convex dust cap (ifakwe ukubonakala njenge-plug yesigaba) ekuqaleni. I-crossover in the entsha ine-resistors eyodwa nje kodwa inani elifanayo lama-capacitors nama-chokes. Zonke izingxenye zinobukhulu obufana nezangaphambili futhi, sithatha, ukubaluleka okufanayo noma okungenani kuseduze kakhulu.
Ngenhlanhla, nginendlela enembile futhi enembile nenqubo yesayensi yokuthola ukuthi kukhona yini umehluko phakathi kwezinhlelo ezintsha nezindala: i-analyzer yami ye-Clio 10 FW, engisebenza ngayo ngokuhambisana nomkrofoni we-Clio MIC-01. I-Clio ingasitshela kahle ukuthi kwenzekani ngokukala impendulo yevamenti ye-entsha ukuze ngiyiqhathanise ngqo nezilinganiso engizithatha zangempela. Ngasebenzisa inqubo yokulinganisa i-quasi-anechoic, nekhrofoni ebekade ibanga elingamamitha ayi-1.

Ukuphindaphindiwe, Impi vs. Monoprice vs. Monoprice
Igrafu engenhla ibonisa impendulo yemvamisa yezikhulumi ze-satellite kusukela ku-Energy Take Classic (umkhondo obomvu), i-Monoprice 9774 (i-trace yegolide) ne-Monoprice 10565 entsha (i-trace green). Njengoba ubona, umehluko phakathi kweMandla kanye nesistimu yaseMonoprice yasekuqaleni ayinaki, kepha umehluko phakathi kwalezi zinhlelo ezindala kanye ne-Monoprice 10565 entsha.
Umehluko omkhulu wukuthi ngemodeli entsha, kunomqondo wokukhulisa ngokuphathelene ne-+3 dB phakathi kuka-1 kHz no-3.6 kHz-mhlawumbe umphumela walowo mshini osusiwe. Lokhu kuphakama okungaba ngu-2-octave-width kufanele kuzwakale ngokuzwakalayo, futhi kumele kube nomthelela wokwenza amazwi abizwe ngokwengeziwe kodwa futhi unikeze izikhulumi umsindo ozwakalayo.
Isibonelo esisha sibonisa ukunwetshwa okuncane okuncane kakhulu, okuhambisana nama-high frequencies phansi -3-DB ku-15 kHz maqondana namamodeli asebekhulile, futhi wehla ngokushesha ngaphezu kwalokho. Lokhu kungasikisela ukuthi imodeli entsha ingase ibe "emoyeni" encane futhi i-ambience iqhathaniswa namamodeli amadala.

Ukuphindaphindiwe, iMonoprice 10565 Satellite
Leli grafu libonisa impendulo yemvamisa ye-satellite 10565 ku-0 ° e-axis (i-trace blue) futhi isilinganiso se-0 ° , ± 10 ° , ± 20 ° no-± 30 ° izilinganiso (ukulandelana okuluhlaza). Ngisho ne-midrange ekhulisiwe, lokhu kusengumphumela omuhle kakhulu, ngokuphendula okunamandla kunezikhulumi eziningi ezibiza kakhulu. Impendulo ye-off-axis ihle kakhulu; impendulo cishe iyafana nefasitela elingu-± 30 elilinganiselwe njengoba liyi-axis. Impendulo ye--3 dB yi-95 Hz, ingcono kune-110 Hz.

Ukuphindaphindiwe impendulo, i-Monoprice 10565 Isikhulumi Sesikhungo
Leli grafu libonisa impendulo yemvamisa yesipikha se-10565 esikhungweni esise-0 ° nge-axis (i-trace blue) kanti isilinganiso se-0 ° , ± 10 ° , ± 20 ° no-± 30 ° izilinganiso (ukulandelana okuluhlaza). Iphinde ikhombise isimo semaphakathi phakathi kwe-satellite speaker. Laba bobabili babonakala benamashayeli afanayo, kodwa isikhulumi esiphakathi sibeka i-tweeter eceleni kwe-woofer esikhundleni se-woofer. Isikhulumi sesiphakathi sinendawo ekhudlwana enezikebhe ezimbili esikhundleni sechweba elilodwa kwisathelayithi. Impendulo ye-off-axis ayihambisani ne-satellites ngoba abashayeli bahlangene-eceleni-kunokuba phezulu-nangaphezulu, kodwa kusengcono kakhulu lapho kukhishwa. Impendulo ye -3 dB ye-bass i-95 Hz, iphinde ibe ngcono kune-110 Hz.

I-Freqeuncy Response, i-Monoprice 10565 i-Subwoofer
Nakhu impendulo yemvamisa yesigaba se-10565 sika-subwoofer esifakiwe, esinomshayeli we-inch angu-8 endaweni evuliwe ekhonjwe yi-amp amp amp elinganisiwe kuma-watts angu-200. Izinyathelo zokuphendula ± 3 dB kusuka ku-33 kuya ku-170 Hz.
Ngiphinde ngenza izilinganiso zokukhishwa kwe-CEA-2010 ku-sub. Ziyamangalisa kakhulu. Wonke amanani abikwe kumamitha angu-1 ngezimfuneko ze-CEA-2010. I-L ngemuva kwalokhu kubonisa ukuthi i-limiter noma inzuzo ephezulu ye-amplifier ivimbele ukuvinjelwa kwe-CEA-2010 ekudlulelweni. Amaphesenti abalwa kuma-pascals.
Ama-ultra-low bass (20 - 31.5Hz) okukhipha isilinganiso: 97.4 dB
20 Hz 86.0 dB
25 Hz 93.7 dB
31.5 Hz 103.8 dB
Ukukhipha isilinganiso esiphansi (40 - 63 Hz) isilinganiso: 115.4 dB
40 Hz 110.1 dB
50 Hz 114.8 dB
63 Hz 119.1 dB L

Impedance, Monoprice 10565 Abakhulumi beSatellite neSikhungo
Leli shidi libonisa impedance yesikhulumi se-satellite esingu-10565 (i-trace blue) kanye nesikhulumi esiphakathi (ukulandelana okuluhlaza). Bobabili isilinganiso esiphakathi kwama-oh ohms angu-7. I-impedance encane ye-satellite i-3.7 ohms ku-350 Hz enezinga lesigaba -9 °. I-impedance encane yesikhungo i-3.4 ohms ku-350 Hz enezinga lesigaba -11 °.
Ukuzwela kulinganiswa nesignali 2.83-volt (1 watt at 8 ohms) kumitha eli-1, isilinganiso esiphakathi kwama-300 Hz kuya ku-3 kHz, kuyinto engu-82.7 dB yesatellite kanye no-83.6 dB phakathi nendawo. Ngakho-ke, lezi zikhulumi zingakhokhisa kancane kancane am amp amp , kepha zizohamba kahle ngokuthola isitholi se-A / V.
