Zokweza mawu kwa 70-90 zikwi. zł - gawo II
Magazini ya Marichi ya "Audio" ikupereka mayeso ofananiza a olankhula asanu pamitengo ya 70-90 rubles. zloti. Kawirikawiri, zinthu zamtengo wapatali zoterezi zimaperekedwa m'mayesero osiyana, pokhapokha chifukwa cha malo omwe amafotokozedwa ndi mapangidwe ovuta komanso apamwamba. Komabe, "Young Technician" amatenga mwayi wopereka mutu wosangalatsawu mwachidule womwe umagwirizana ndi mawonekedwe ake.
Chilichonse cha zokuzira mawu chomwe chimaperekedwa chimakhala chosiyana kotheratu, kusonyeza kudzikonda kwa anthu opanga ndi makampani kotero kuchuluka kwa mayankho omwe tili nawo omwe tili nawo pankhani yaukadaulo wamayimbidwe. Tidawonetsa zabwino ndi zoyipa zamapangidwe a Avanter III a kampani yaku Germany Audio Physic. Ino ndi nthawi ya SOPRA 3 kuchokera ku Focal. Zitsanzo zitatu zotsalazo ziziwoneka motsatira zilembo m’zigawo zotsatirazi. Ngati mukufuna kufotokozera mwatsatanetsatane zonse zisanu, zonse zokhudzana ndi luso, maonekedwe ndi miyeso, komanso malipoti omvera, chonde pitani ku Audio 3/2018.
Yang'anani PAMWAMBA 3
Kwa zaka zopitilira makumi awiri, Focal Utopia yotchuka yakhala gawo lofunikira kwambiri pamibadwo yotsatira. Pazaka zingapo zapitazi, Focal yakhala ikuyambitsa mitundu ya Sopra pazakupereka, m'njira zambiri mpaka kufika pamlingo wa Utopia.
Poyambitsa mayankho omwe adawonetsedwa mu mndandanda wa Sopra, Focal idadzitamandira zatsopano zomwe sizinapezeke pamndandanda wa Utopia. Sopra 2 idayambitsidwa koyamba (kupambana mphotho ya EISA), ndikutsatiridwa posakhalitsa ndi yaing'ono (yoyima) ya Sopra 1, ndipo chaka chapitacho inali yayikulu kwambiri pamndandanda wa Sopra 3.
Chitsanzo cholembedwa ndi makona atatu ndi ofanana kwambiri ndi mawonekedwe ndi makonzedwe a Sopra 2. Zimasiyana makamaka ndi kukula kwa woofers ndipo, motero, mu kukula kwa kabati. Olankhula amakhala m'njira yofananira ndi ma Focals ambiri - midrange (16 cm) "amakwezedwa" pamwamba pa tweeter, chifukwa ali pamtunda woyenera (makutu a womvera wokhala pansi), ndipo pansi pamakhala chokulirapo. gawo la woofer gawo (lokhala ndi olankhula 20 cm). Electroacoustic, dera nthawi zambiri limakhala lamagulu atatu.
Kupotoza nduna yonse kuti nkhwangwa zokamba za zigawo zonse zidutse patsogolo pa wokamba nkhani, mochulukirapo kapena mochepera pa malo omvera, amakhalanso ndi chikhalidwe chachitali mu mapangidwe a Focal kuyambira m'badwo woyamba wa Utopia ndipo akupitirizabe lero ku Utopia. , mndandanda wa Sopra ndi Kant. Mu iliyonse ya iwo, kamangidwe kameneka kankachitika mosiyana, pang'ono potengera kukula ndi bajeti, komanso mwayi watsopano ndi kusintha mafashoni. Ku Utopias, tili ndi magawo omveka bwino, ndipo mu Sopry, kusintha kosalala pakati pa ma modules; ngakhale machitidwe a Utopia ali ochuluka kwambiri, olimbikira ntchito komanso apamwamba, maonekedwe a Sopra ndi amakono kwambiri. Kugwiritsiridwa ntchito kwa zigawo za aluminiyamu (osati chromed kapena oxidized), khalidwe la Sopra, kumawonjezera kumveka kwake, ndipo pamodzi ndi mitundu yeniyeni, imatanthawuza pang'ono mawonekedwe a magalimoto amasewera. Dome la tweeter limatetezedwa nthawi zonse ndi mesh yachitsulo - apa ndibwino kuti musadalire chenjezo la wogwiritsa ntchito, chifukwa zidzakhala zodula kwambiri kuwononga dome la beryllium. Pankhani ya nembanemba, Sopra samasiya njira zabwino kwambiri za Focal - beryl (mu tweeter) ndi sangweji ya W (sangweji yopangidwa ndi zigawo zakunja za fiberglass ndi thovu lolimba pakati pawo). Ku Sopry, kusintha kwakukulu kunapangidwa kwa dalaivala wa midrange, zomwe zimaphatikizapo, mwa zina, kuyimitsidwa kwa misa, ndi makina opangidwa bwino kwambiri a maginito, omwe adapangitsanso kusintha mawonekedwe a diaphragm kuchokera ku conical yapitayi kupita ku exponential. , m'zigawo zina. oyenera kwambiri olankhulira pakatikati. Chipinda chokhala ndi mbiri yayitali chakonzedwa kwa tweeter - ngalande yomwe imathera mu kagawo kakang'ono, kokongoletsedwa ndi grille yayikulu kumbuyo. Uwu ndi mtundu wa kukokomeza mawonekedwe kuposa zomwe zili. Kutentha koyenera komanso kopanda phokoso kuchokera kumbuyo kwa dome sikungafune kukulitsa koteroko, koma unali mwayi wabwino, popeza module ya tweeter imathandizanso "kupindika" kapangidwe kake.
Kabatiyo imakhala yopindika (chifukwa cha kulumikizika kwa nkhwangwa zolankhulira zazikulu zomwe tazitchula pamwambapa) ndipo ili ndi mbali zopindika (zomwe zimachepetsa mafunde oyimirira mkati). Ilinso ndi kutsogolo kokhotakhota ndi utali wozungulira waukulu, wozungulira wozungulira pakati pazipupa zam'mbali ndi kutsogolo (chifukwa chomwe mafunde amatuluka m'thupi popanda kugunda m'mbali zakuthwa). Chophimbacho chimapangidwa ndi galasi la masentimita awiri. Thupi lokha limakwezedwa ndikupendekeka ndi zida ziwiri, nthawi yomweyo kupanga kupitiliza kwa gawo la inverter.
Sopra 3 imawoneka yopepuka chifukwa cha mawonekedwe ake, koma pa 70kg ndiyolemera kwambiri pamitundu isanu poyerekeza.
Zimagwira ntchito bwanji, i.e. zida mu labotale
Makhalidwe a Sopra 3 akuwonetsa kukweza komveka bwino kwa bass, zomwe zikuwonetsa kuti wokambayo ayenera kugwiritsidwa ntchito m'zipinda zazikulu. Panthawi imodzimodziyo, mafupipafupi apakati apakati amakhala oyenerera bwino. M'kati mwa 500 Hz - 15 kHz, osati motsatira mbali yaikulu, khalidweli limasungidwa mumtundu wopapatiza wa +/- 1,5 dB. Kubalalitsa kwakukulu ndikwabwino kwambiri. Pamunsi, pali -6 dB kuchepetsa kuchokera pamlingo wapakati pafupipafupi 28 Hz - zotsatira zabwino kwambiri. Monga tikuyembekezeredwa, tikulimbana ndi mapangidwe a 4-ohm ndi kukana kochepa kwa pafupifupi 3 ohms (pa 100 Hz), kotero ndife okonzeka kugwira ntchito ndi amplifiers "athanzi". Wopanga amalimbikitsa mphamvu mumtundu wa 40-400 Watts, zomwe zimawoneka zomveka (mphamvu zovotera zimatha kuwerengedwa pa 200-300 Watts).
