中置好似燒左，求救

剛剛睇睇下戲，中置冇晒聲
好似燒左咁，我換另一中置試
正常，AMP 冇事

開左個中置，用錶他佢，冇 ohm 反應
係咪死左? 有冇得救?

謝謝

可以將燒o左的中置挪到鴨記，有專維修喇叭的店舖，因為在下都唔識維修！

用錶他佢，冇 ohm 反應  :shock:

8 ohm speaker 應該有 8 ohm    

應該係燒左但唔肯定燒Coil定接線 , 真係要挪到鴨記睇睇  

係咪淨係拆出來果嗰隻 :? 如果唔係 ......:cry:  :cry:  :cry:

For the normal design of a speaker,

The woofer / mid range should be in-series of inductor. If the amp have high power or DC components happen, the woofer / midrange can be damage.

You can use a simple "analog moving coil meter" to measure the resistance of the coil in DC mode. It should be around 8 ohm "resistance"

If totally open circuit, your coil may be damage.

On the other hand, you can use the meter to measure the "tweeter", normally, the tweeter will in series of a capacitor which is protect the DC components from the Amp and another function is a simple first order cross over filter.

Any problem, please call me.
