always...better wood better sound...
MDF..cheap..but random outcome..as they absorb
PLY wood is a good alternative i suppose..Indonesia Ply..holand ply..etc? or China Ply..
or coz.will be some..other kind of excotic hard wood around...
i think...worth to try with some HDF...or..Plywood..

I am thinking...to hire a carpenter - one working day...who can make 6  of them at least....and material cost less than HK$100 and man hour is HK$800...so on average...HK$240 each.... good..

這個系松板。你可用髙密度的人工合成板。密度超髙聲音越好

長長影子

咁嘰尺寸最佳擴散範圍約 1.2 kHz ~ 6.9 kHz, 但 fo 到去成34 kHz, 做到咁高 prime no., well width 咁窄又冇用栅片隔開, 咁設計好似浪費左少少咁喎...
