Isandi esithe ngqo sisandi esikhutshwa sisithethi size sifikelele ngqo kubaphulaphuli. Uphawu lwaso oluphambili kukuba isandi sicocekile, oko kukuthi, loluphi uhlobo lwesandi esikhutshwa sisithethi, umphulaphuli uva phantse uhlobo luni lwesandi, kwaye isandi esithe ngqo asidluli kwimbonakalo yegumbi yodonga, umhlaba kunye nomphezulu, asinazo iziphene ezibangelwa kukubonakaliswa kwesandi sezinto zokuhombisa zangaphakathi, kwaye asichaphazeleki yindawo ye-acoustic yangaphakathi. Ke ngoko, umgangatho wesandi uqinisekisiwe kwaye ukuthembeka kwesandi kuphezulu. Umgaqo obaluleke kakhulu kuyilo lwanamhlanje lwe-acoustic yegumbi kukusebenzisa ngokupheleleyo isandi esithe ngqo esivela kwizithethi kwindawo yokumamela nokulawula isandi esibonakalayo kangangoko kunokwenzeka. Egumbini, indlela yokufumanisa ukuba indawo yokumamela inokufumana isandi esithe ngqo kuzo zonke izithethi ilula kakhulu, ngokubanzi kusetyenziswa indlela yokubona. Kwindawo yokumamela, ukuba umntu okwindawo yokumamela unokubona zonke izithethi, kwaye ukwindawo apho zonke izithethi zijikeleziswe khona, isandi esithe ngqo sezithethi sinokufunyanwa.

Kwiimeko eziqhelekileyo, ukumiswa kwesithethi sesona sisombululo silungileyo sesandi esithe ngqo kwigumbi, kodwa ngamanye amaxesha ngenxa yokuba isithuba esiphantsi kunye nendawo encinci kwigumbi, isithethi esimiswe sinokuba phantsi kwemiqathango ethile. Ukuba kunokwenzeka, Kucetyiswa ukuba uxhome izithethi.

I-engile yokukhomba uphondo lwezithethi ezininzi ingaphakathi kwama-60 degrees, i-engile yokukhomba ethe tye inkulu, i-engile ethe nkqo incinci, ukuba indawo yokumamela ayikho ngaphakathi kwe-engile yokukhomba uphondo, isandi esithe ngqo sophondo asinakufunyanwa, ngoko ke xa izithethi zibekwe ngokuthe tye, i-axis ye-tweeter kufuneka ihambelane nenqanaba leendlebe zomphulaphuli. Xa isithethi sixhonywe phezulu, into ephambili kukulungisa i-engile yokuthambekela kwezithethi ukuze kuthintelwe ukuchaphazela isiphumo sokumamela se-treble.

Xa isithethi sidlala, okukhona sisondela kwisithethi, kokukhona isandi esithe ngqo sikhula, kwaye isandi esibonakalayo sincinci; okukhona sikude kwisithethi, kokukhona isandi esithe ngqo sincinci.
