1. Kodi tanthauzo la mawu akuti wokamba nkhani wa mbali ziwiri ndi wokamba nkhani wa mbali zitatu ndi chiyani?
Cholankhulira cha mbali ziwiri chimapangidwa ndi fyuluta yodutsa kwambiri ndi fyuluta yodutsa pang'ono. Kenako fyuluta yolankhulira ya mbali zitatu imawonjezedwa. Fyulutayo imapereka mawonekedwe ochepetsera mphamvu ndi malo otsetsereka okhazikika pafupi ndi malo ogawa ma frequency. Malo olumikizirana a magawo owonongeka a ma curve oyandikana nthawi zambiri amatchedwa malo ogawa ma frequency. Pali gulu lolumikizana pafupi ndi chogawa, ndipo mu gululi ma speaker onsewa amakhala ndi zotuluka. Mwachidziwitso, kuchuluka kwa attenuation ya fyuluta, kumakhala bwino. Komabe, kuchuluka kwa attenuation mphamvu, zigawo zambiri, kapangidwe kovuta, kusintha kovuta, komanso kutayika kwakukulu kwa insertion.

Malo ogawa ma speaker awiri ali pakati pa 2k mpaka 4KHz, Ngati mphamvu ya treble ndi yayikulu, malo ogawa ayenera kukhala otsika, ndipo mayankho a directivity frequency adzakhala abwino. Mwachitsanzo, mphamvu ya treble ndi yaying'ono, malo ogawa akhoza kukhala okwera kwambiri. Pogawa ma treble, ma frequency apakati ndi bass, kulamulira mawu kumakhala kowonekera bwino.
2. Kusiyana pakati pa wokamba nkhani wa mbali zitatu ndi wokamba nkhani wa mbali ziwiri:
1) Kapangidwe kosiyana: bokosi la okamba nkhani awiri nthawi zambiri limakhala ndi mayunitsi oposa awiri, treble unit ndi bass unit; Bokosi la okamba nkhani atatu nthawi zambiri limagawidwa m'mayunitsi atatu kapena kuposerapo, kuphatikiza treble unit, alto unit ndi bass unit.
2) Kapangidwe kake ndi kosiyana: bokosi la bokosi la sipika la mbali ziwiri lili ndi mabowo awiri a nyanga; Bokosi la sipika la mbali zitatu lili ndi mabowo oposa atatu a nyanga.
3) Makhalidwe osiyanasiyana: mphamvu ya mawu ndi mtundu wa mawu a sipika ya mbali ziwiri ndi zabwino; Bokosi la sipika ya mbali zitatu limapangitsa nyimbo kukhala yogwirizana kwambiri chifukwa limagawa ma frequency malinga ndi makhalidwe a ma frequency a mayunitsi osiyanasiyana.
