有位朋友借咗一個自己diy嘅地盒畀我，就係上次我post條link出嚟圖中果一個，
如果認識小弟相信都知小弟比較信數據，唔喜愛神化一啲配件，
自己啲subwoofer都只係用緊黑雞電源線，
但今次用咗呢個地盒後係整體上真係有好大嘅improvement，
當中包括:-
而以小弟朋友所分享做地盒無任何數計或電子計算，只留意以下幾點就可以做出唔錯效果嘅地盒:-
1. 電器石數目
2. 電器石及導電體的接觸面
3. 防潮
4. 防震
簡單嚟講個箱內面嘅設計係做到最多石接觸最大面積嘅導電體，
而個朋友個箱大約係一部Oppo Blu-ray Player咁大，
總重量約35lbs，見自己個器材架重有一格多出嚟，
嚟緊打算自己做一個大約一部後級機箱咁大嘅地盒，
大約用100lbs石。
睇下呢度啲大佬有無人diy過，想再偷下師。
利申: 小弟同果位朋友都係打算自己DIY，
無打算出售或幫人做(因為真係太重，搬唔陏)，
反而希望多啲朋友自己DIY可以交流到箱體內唔同設計嘅效果，
因為做地盒真係無乜特別技術需要，而齊料後整個過程朋友話一個鐘內攪掂。
厘幾樣野點既數據?
要啲咩數據? 接完地盒未有時間cal過部投影，有時間會睇睇。
一路同朋友諗為何個地盒喺小弟屋企有咁大效果，
估計可能我屋嘅ground loop太利害，
如果將成個system改為單點落地後先加地盒個效果就可能變得無咁明顯。
地盒對switching psu幫助好大,試過接Emmlab Dac AB比較.
而對Linear psu影響可以係好同壞,所以點去平衡物料係好重要,
唔係木馬地盒賣咁貴重有人買.
Raymond hing, 你第日嘅AV HOUSE，咁當然用銅柱直接打入地深啦。
講真我對物理一知半解，無乜理論可以分享到，
頂盡到落手做時影下相。

I really like to learn more on the building up of the earthing box as well as the associated results from you.
For UK house, I will use a dedicated electric circuit for the AV room. If possible, I will install an earthing copper rod at the rear garden.
However, for the HK home, I may need to use your guide to build similar earthing box for trial to see the effectiveness.
Hence, your sharing on any related information such as materials use, source and cost as well as the step-by-step photos showing us the way to build it up.
For the AV Room in UK, I will start the planning on all associated fixtures including sound insulation, absorption, reflection, etc.
Since I have no knowledge on the block work wall, wood panel ceiling, etc, the acoustic conditions may be different from HK conditions of all concrete wall/ceiling/floor.
Does anyone has the experience on the erection of AV room in a house with brick work / block work wall & ceiling ?
Please share the info and acoustic technique / treatment with me.
Dimensions of AV Room : 25'10" (L) x 12'4" (W) x 8'5" (H)
