PMC Twenty5-26 喇叭

ericho

各位C Hing:
我有些問題如下，希望你門能幫忙解決:

1. 我在November 2019 年買了 PMC Twenty5-26 喇叭，但 run in 至今，人聲的尾音依然很刺耳 (i.e. Shee....Shee 聲)｡ 我應如何處理和解決好｡

2. 很多人說，amplifier 要大瓦數(100-200W) 先至會推得 PMC Twenty5-26 喇叭好聲，這是否要張音量調高或加大，才能有好的效果。請指點迷津。

謝謝 !

師兄，唔一定關喇叭事，可能係線材！！！

May be too many Nordost cables in your system, try pure copper cable...

多謝各師兄指點，如需轉用線材，應如何著手？Which unit and what type of copper cable should I need to alter for improvement of the sounding ?

u might use 2 normal black cheap cables to test if the weird sound relates to the power cables or the electricity of your home.

On the other hand, speaker normally needs 500 hrs to run in.

Yes, too many cables in the same brand is not a smart choice.  Characters of the brand are too strong.

ericho

You are right. Your proposal to use two cheap power cables for testing the weird/harsh sound is good ideal.  Thanks, C-Hing.

I am using FACT 8 signature. Driven by Krell Integrated K300i using Wireworld Platinum speaker cable and Audience SX power cable.

Vocal is very smooth and focus and it has a very deep sound stage already just within the first few hours out of the box.

I think your problem is too much Nordost cable.  Try some other speaker cable first (pure copper one would be a safe route) and then consider the others.
