Cov khoom no yog ib tug passive #hais lus, tsis muaj ib tug built-in hwj chim amplifier, nws xav tau ib tug sab nraud lub hwj chim amplifier siv. Muaj feem xyuam rau: hloov tsheb CD rau kev siv hauv tsev, kev ua yeeb yam hauv tsev ua tus hais lus tseem ceeb lossis ib puag ncig lub thawv, qhia tus hais lus lossis lub rooj sib tham, thiab lwm yam.
Passive #hais lus yog qhov zoo tib yam #hais lus uas peb feem ntau siv yam tsis muaj lub zog amplifier Circuit Court sab hauv. Txawm hais tias passive #hais tsis muaj amplifiers, lawv feem ntau muaj crossover networks thiab impedance them circuits. Active #hais lus feem ntau yog cim nrog cov tsis xws li lub zog tso zis, input impedance, thiab input teeb liab theem ntawm built-in amplifier.

1. 2 "tag nrho daim ntawv lub khob hliav qab treble suab riam phom yog ntuj, du thiab meej
2. 4 "kev tshaj lij mid-bass suab surging sib haum xeeb thiab huv si, ruaj khov thiab nrov suab teb, yooj yim los tswj ntau yam kev siv scenarios
3. Lub pem hauv ntej hyperboloid qhia raj yog flexibly muab tso rau ntawm lub desktop thiab phab ntsa, yog li ntawd cov huab cua ntws yuav ntws smoothly tsis muaj kev hloov tam sim ntawd. Piv nrog rau qhov zoo tib yam inverted raj, nws muaj peev xwm ua tau zoo zam lub airflow whistling suab thiab lub suab yog purer, thiab tsawg zaus dab dej yog thicker.
