Momwe mungasankhire subwoofer yabwino kwambiri

Mofanana ndi ma speaker okhazikika, mawonekedwe a subwoofer amatha kukhudza njira yogulira. Kutengera zomwe mukufuna, izi ndi zomwe muyenera kuyang'ana.

Mafupipafupi

Ma frequency otsika kwambiri a subwoofer ndi phokoso lotsika kwambiri lomwe dalaivala wa sipika angapereke. Ma frequency apamwamba kwambiri ndi phokoso lokwera kwambiri lomwe dalaivala angapeze. Ma subwoofer abwino kwambiri amapanga phokoso lofika pa 20 Hz, koma munthu ayenera kuyang'ana ma frequency range kuti awone momwe subwoofer imagwirizanirana ndi stereo system yonse.

Kuzindikira

Mukayang'ana ma specs a ma subwoofers otchuka, yang'anani mphamvu ya mawu. Izi zikusonyeza kuchuluka kwa mphamvu zomwe zimafunika kuti pakhale phokoso linalake. Mphamvu ya mawu ikakwera, subwoofer imafunikira mphamvu zochepa kuti ipange besi yofanana ndi sipika ya mulingo womwewo.

Mtundu wa kabati

Ma subwoofers otsekedwa omwe ali kale m'bokosi la subwoofer nthawi zambiri amakupatsirani mawu akuya komanso odzaza kuposa osatsekedwa. Chikwama chokhala ndi mabowo ndi chabwino kwambiri pamamvekedwe amphamvu, koma osati mawu akuya kwenikweni.

Kusakhazikika

Impedance, yoyesedwa mu ohms, imagwirizana ndi kukana kwa chipangizocho ku mphamvu yamagetsi kudzera mu gwero la mawu. Ma subwoofers ambiri ali ndi impedance ya 4 ohms, koma mutha kupezanso ma subwoofers a 2 ohm ndi 8 ohm.

Chozungulira cha mawu

Ma subwoofers ambiri amabwera ndi cholumikizira mawu chimodzi, koma okonda mawu odziwa bwino ntchito kapena okonda kwambiri nthawi zambiri amasankha ma subwoofers awiri a cholumikizira mawu. Ndi cholumikizira mawu awiri, mutha kulumikiza makina amawu momwe mukufunira.

Mphamvu

Mukasankha subwoofer yabwino kwambiri, onetsetsani kuti mwayang'ana mphamvu zomwe zayesedwa. Mu subwoofer, mphamvu ya RMS ndiyofunika kwambiri kuposa mphamvu zomwe zayesedwa. Izi zili choncho chifukwa imayesa mphamvu yopitilira m'malo mwa mphamvu zomwe zayesedwa. Ngati muli kale ndi amplifier, onetsetsani kuti subwoofer yomwe mukuyang'ana ikhoza kuthana ndi mphamvu zomwe zatulutsidwa.
