听《机遇》琴姐的独白驻波特别厉害,应是中低频吧。
音箱后墙有落地窗廉,但侧墙和后墙上什麽都没有,想挂一些毛巾质的东西,不知应挂在什麽位置和高度。

经madog兄指点后,重起兄的系统有什么改善的地方?

嘿嘿谢阿邓兄关心,近来工作较忙,器材和环境没做任何改动,深夜能用小音量听半小时就觉很幸福了,可能还要持续两三个月。

不过已有计划,先对后墙作像Viola试音室那样的处理,用吸音材料放在邓兄指示的位置,因除了驻波外也发现有部分高频段有飘移,最终在墙角作低音陷阱。线材暂时不打算换,怕损失动态和低频。

madog 兄已经提供了这么专业的关于音响调校的知识,相信经 重起兄 悉心摆弄后,音响系统的表现从此以后会更上一层楼。

有两点提议给重起兄:

1、从环境处理、摆位等方面下功夫,以你现在的器材,如果得到发挥,相信会有相当好的表现。这方面可以借助madog兄非常丰富的专业知识。等系统得到正常发挥或发挥到一定的水平后,才去作一些改变它的原设计的尝试,估计那样会更好。

2、做环境处理时,还要考虑如何把它装饰得舒适一点,优雅一点。试想在一个声学处理得当,舒适优雅的环境里欣赏音乐,该是如何的写意!

[OK, tell me your ceiling height as well. Better still tell me your models of
equipments and cables. etc.

I'll let you know tomorrow. Got to go to bed.


Ceiling height is around 2.5m

CD player: Marantz CD6000 OSE
Int tube Amp: Mei-xing 3008 AB (300B driving 805 single end 40W x 2)
Speakers: Harberth HL-Compact
Interconnect cable: Audioquest Diamondback
Spk cable: Das Monitor copper 5.0mm bi-wiring

Have a good sleep, let music be in your dreams.



Sorry forgot to tell you. I think the booming midrange is come from your
speaker cable.

First of all, American interconnect is heavy in low register, soundsl  more
like a cowboy.

Your speaker cable if is of hard wire (single core) 5mm, this will become a
disaster. If it is true 5mm single core, midbass boom is heavy.

You may not change you interconnect but first change the speaker cable
if it is 5mm solid core.

Try some lighter weight cable, such as multi-strand but don't be greedy for
few hundred strands otherwise the bass quantity will be overwhelming
that will eventaully cover up the midrang clarity.

Same to power cord. You may sick to the original power cord well
otherwise thick power cord also contribute too heavy bass and midrange.

Cheers and have fun
