Room acoustic我都有研究過一段時間，用REQ 測過room frequency response後訂了些Gik acoustic bass trap ...

Physic wise, I don't think the resonators will work, especially for low frequency.
Acoustics foam does not absorb low frequency well, so may have to use fiber glass or rockwool panel.

I am currently using acoustics foam plus Sonarworks room correction and the result is amazing. I am 100% sure Sonarworks is cheaper and better than resonators.

Planning to upgrade most foam to rockwool, but will need to DIY.

我都好同意係較房仲好... 但唔係人人識, 又太多變數. 好似我對CHEAP野有源, 唔講高低音果D, 試機果時穿 ...

    Yep, I know. My space is limited as well.
That's why I am just using limited acoustics foam and Sonarworks room correction.
And use nearfield speaker since it depends less on the room.

    300hz 下減幾個db 就真，個low freq 大部份房都撞到九彩。
frequency response 只係一部份，仲有好多野要較。

This is what I currently using

我最早也是用foams， eg: auralex， 然後自己DIY glass fiber panel at the corner
但由於foams太難打理，就定了GIK acoustic panels

效果係上面個post入面都見到
而聖杯其實一直都有用緊，效果好睇個用家識唔識得set up，而其針對的地方同bass trap唔同，二者可以並存
最後對於Room EQ其實比較抗拒，各種原因我應該唔會考慮用

聖杯係咩原理呢？幾銀；

Ching, I hate to say, but
well, I would say the test report is not professional at all.
Publishing a draft report in public domain without mentioning who is responsible (the actual person) and the qualification of such person is highly unprofessional.

I would trust proven science, instead of betting money on un-proven science or what probably is a high level scam.

Don't under estimate the power of psychological effect.

Since you have a measurement microphone and software, why don't you measure the Frequency response and phase response before and after applying the resonators?

I'm not able to see any difference on the graphs, since my mesauring equipment is not that sensitive.

Actually the freq response not even change(varation observed, but no specific pattern) by putting those panels on, does that mean these panels are scam? I don't think so...

BTW, I'm using a superlux ECM999 as the mesaurement mic

    If there are no change on Frequency Response nor Phase Response, then it is 100% scam.

Sorry to say that.
