1.Ithini inkcazo yesithethi esineendlela ezimbini nezintathu?
Isithethi esineendlela ezimbini siqulunqwe sisihluzo sokupasa okuphezulu kunye nesihluzo esisezantsi.Kwaye ke indlela ezintathu zokucoca isithethi zongezwa.Isihluzi sibonisa uphawu lokuthomalalisa kunye nethambeka elizinzileyo kufutshane nendawo yokwahlulwa kwamaza.Ukudityaniswa kwezigaba zokubola kwamagophe akufutshane kudla ngokubizwa ngokuba yi-frequency division point.Kukho ibhendi ethelelanayo kufutshane nesahluli, kwaye kweli qela zombini izithethi zineziphumo.Ngokwethiyori, okukhona umkhulu umyinge wokuthomalalisa wesihluzi, kokukhona ungcono.Nangona kunjalo, ubukhulu bezinga lokunciphisa, amacandelo amaninzi, isakhiwo esiyinkimbinkimbi, ukulungiswa okunzima, kunye nelahleko enkulu yokufaka.

Indawo yokwahlula isithethi esineendlela ezimbini iphakathi kwe-2k ukuya kwi-4KHz, Ukuba amandla e-treble makhulu, indawo yokwahlula kufuneka ibe sezantsi, kwaye impendulo ye-directivity frequency iya kuba ngcono.Ngokomzekelo, amandla e-treble amancinci, indawo yokwahlula ingaba phezulu kuphela.Ngokwahlula i-treble, i-mid-range kunye ne-bass frequencies, ulawulo lwesandi lubonakala ngakumbi.
2. Umahluko phakathi kwesithethi esineendlela ezintathu kunye nesithethi esineendlela ezimbini:
I-1) Ukwakhiwa okwahlukileyo: ibhokisi yesithethi esineendlela ezimbini ngokubanzi ineeyunithi ezingaphezulu kweeyunithi ezimbini, iyunithi yetreble kunye neyunithi ye-bass;Ibhokisi yesithethi esinendlela-ntathu yohlulwe ngokubanzi ibe ziiyunithi ezintathu okanye ngaphezulu, kubandakanywa iyunithi yetreble, iyunithi ye-alto kunye neyunithi ye-bass.
2) Ulwakhiwo lwahlukile: ibhokisi yebhokisi yesithethi esineendlela ezimbini inemingxuma emibini yeempondo;Ityala lesithethi esineendlela ezintathu linemingxuma engaphezu kwemithathu yeempondo.
3) Iimpawu ezahlukeneyo: isiphumo sebala lesandi kunye nomgangatho ovakalayo wesithethi esineendlela ezimbini zilungile;Ibhokisi yesithethi esineendlela ezintathu yenza umculo ube nenqanaba eliphezulu ngakumbi kuba yahlula-hlula iifrikhwensi ngokweempawu zefrikhwensi yeeyunithi ezahlukeneyo.
