Lezi zivivinyo zokubona zibaluleke kakhulu lapho kulungiselelwa imikhiqizo efana Izinhlelo ezingenazandla zezimoto, izikhulumi ezihlakaniphile, noma izinhlelo zemihlanganolapho ukuqondakala kanye nenduduzo yokulalela kubaluleke kakhulu, noma ngisho nangaphezu kwalokho, ukwethembeka okumsulwa. Ukuba nalezi zilinganiso ezihlanganiswe endaweni efanayo ye-APx lapho amazinga, ukubambezeleka, kanye nempendulo yemvamisa kulinganiswa khona kusiza ukunikeza umbono ophelele wokuziphatha kwesistimu.
Ngazo zonke lezi zingxenye—izilinganiso ze-electroacoustic ezithuthukisiwe, ukuhlolwa okusheshayo kokukhiqiza, izinsiza zesithombe, ukuzenzekela okusekelwe ku-API, kanye nezilinganiso zokuqonda—umndeni we-APx kanye nesofthiwe ye-APx500 kuhlanganiswe njenge ipulatifomu ephelele kakhulu yokuklama, ukuqinisekisa kanye nokukhiqiza imikhiqizo yomsindoKungakhathaliseki ukuthi ukulinganisa ukubambezeleka kanye nemvamisa kumodeli we-soundbar noma ukuqapha ikhwalithi yezikhulumi eziyizinkulungwane ngosuku, uhlelo lwe-ecosystem olunikezwa yi-Audio Precision luhlanganisa lonke uchungechunge lwenani kusukela ekuqaleni kuze kube sekupheleni ngokuqina kobuchwepheshe namathuluzi aklanyelwe umsebenzi wangempela.
Umbhali oshisekayo ngomhlaba wamabhayithi nobuchwepheshe ngokujwayelekile. Ngiyathanda ukwabelana ngolwazi lwami ngokubhala, futhi yilokho engizokwenza kule bhulogi, ngikubonise zonke izinto ezithakazelisayo kakhulu ngamagajethi, isofthiwe, ihadiwe, izitayela zobuchwepheshe, nokuningi. Inhloso yami ukukusiza ukuthi uzulazule emhlabeni wedijithali ngendlela elula nejabulisayo.
