聽一首歌開大聲時，感覺到啲聲開始變差，點分係amp到咗極限定喇叭到極限

不如, 你講下咩 Amp, and 咩 speakers,

rotel 合併/ jvc speaker

Rotel 合併, 幾多 W 輸出?? 信七, 八成好啦

60w

Amp 如果唔多够力, 强開大聲, 好易燒 speaker

60W /channel, 定係 total, 你都唔積極, 要人問一句, 你就答一句!!點玩 Hi-Fi 架??

咁似D港女。。。

jvc 乜 speaker??

SX-900?

sx-a103,點試到係邊樣野，唔知邊位ching知

好似審犯咁, 問一句, 答一句, 由頭到而家, 唔該都冇聲, 別人奉旨要教你嗎??

學左禮貌先再學玩 Hi-Fi 吧

我唔係問你，你可以唔答，不過都同你講聲"唔該“

那看誰教你吧, 咁誨氣!!

一水般而言, 聽一首歌開大聲時，感覺到啲聲開始變差, 通常都是amp的問題, 我曾以幾萬元的amp去推幾佰元喇叭, 開大聲也沒事, 你所指的聲音變差, 是否聲音變尖, 拆聲, 這是失真,失控的徵兆

Easy, play your favourite music, and use a CRO to read the output connected to your speaker. Check if there is any CLIPPED waveform esp. at low frequencies.
Or, use a signal generator connected to your pre-amp, set at 50Hz to 80Hz, and drive your speaker and read the output of the power amp using a CRO. Turn up the volumn slowly. If the CRO still shows a perfect sine wave and the speaker is already bottom out, then the speaker cannot handle the power of your amplifier.
You may also check the specifications of the amp and speaker to see if their power output and input figures are matched. But there is some tricks to decide a proper power level during this case.

Speakers are not pure resistive. I wonder if the waveform shown on a CRO is a good looking sine wave?

哈哈哈...十爺唔好咁勞氣啦.

啲聲開始變粗及有亂的感覺

請問CRO係咪顯示波頻機
