Lub tweeter ntawm lub tshuab hais lus ob txoj kev ua haujlwm tseem ceeb ntawm tag nrho cov zaus siab. Nws qhov tweeter ntawm lub tshuab hais lus kom dais tag nrho lub zog ntawm qhov zaus siab, txhawm rau ua kom lub tweeter no tsis txhob thauj khoom ntau dhau, yog li koj tsis tuaj yeem xaiv lub tweeter nrog qhov crossover qis, yog tias koj xaiv qhov crossover qis yuav ua rau lub tweeter ntawm lub tweeter yuav dhau los ntawm lub zog loj heev, uas yuav ua rau lub tweeter hlawv, nyob rau hauv qhov xwm txheej ib txwm muaj, lub tweeter qhov crossover yuav tsis ntau tshaj 2,000 hertz!

Lub tweeter kuj tseem yuav tsum tau siv ua ke nrog lub woofer. Tib lub sijhawm, peb kuj yuav tsum xav txog qhov txwv qis ntawm tweeter, txwv tsis pub, yuav muaj kev sib txuas tsis zoo ntawm ob lub zaus. 6.5-nti tus neeg hais lus qhov txwv siab ntawm zaus feem ntau tsis siab dua 5,000 Hz, thaum peb tsim qhov crossover point, yog tias peb tawm ob npaug ntawm qhov zaus, ces qhov crossover point ntawm qhov tsim nyog siv tus nqi ntawm kwv yees li 2.5000 Hz, zoo ib yam li qhov txwv qis ntawm tweeter, yog tias kuj raws li tib yam tawm ob npaug ntawm zaus los xam, ces nws yuav tsum qis dua 1.2500 Hz. Ob npaug ntawm zaus los xam, nws yuav tsum qis dua 1.2500 Hz.

Rau qhov yuav tsum tau ua ntawm lub tweeter, ua ntej tshaj plaws, qhov zaus resonant F0 tsis tuaj yeem siab dua ib nrab ntawm qhov zaus ntawm qhov crossover point, txwv tsis pub, nws yuav ua rau qhov crossover point nyob rau hauv qhov chaw ntawm qhov zaus teb yuav yog teeb meem, qhov ntau yam tsim nyog yuav tsum yog qhov zaus resonant ntawm tus neeg hais lus tsis siab dua 1.2500 Hz. Yog tias qhov loj me ntawm woofer txhawb nqa tsawg dua 6.5 nti, ntawm lub sijhawm no, qhov txwv qis zaus ntawm tweeter yuav siab dua me ntsis, vim tias ntawm lub sijhawm no lub peev xwm siab zaus ntawm woofer yuav raug txhim kho, qhov crossover point yuav raug tsa, qhov no yog raws li cov yam ntxwv ntawm woofer los txiav txim siab!

Thaum xaiv lub tweeter, peb kuj yuav tsum tau them sai sai rau qhov rhiab heev, hauv paus ntsiab lus, qhov rhiab heev ntawm tweeter tsis tuaj yeem qis dua qhov rhiab heev ntawm woofer. Yog tias nws qis dua nws, nws yuav nyuaj rau txo qhov rhiab heev ntawm tus neeg hais lus los ntawm qee qhov kev txo qis ntawm tus neeg hais lus ib txwm muaj, yog tias qhov hluav taws xob crossover, qhov no tsis tseem ceeb, thaum qhov rhiab heev ntawm tweeter siab dua qhov rhiab heev ntawm cov neeg hais lus bass, peb tuaj yeem siv cov tweeter ntawm cov koob ntawm qee cov resistors uas muaj qee qhov chaw inhibitory los txo ob qho tib si kom ua tiav qhov sib xyaw zoo meej ntawm treble thiab bass.
