| dari tu manual, untuk sealed enclosure
size: 14.2L f3: 49hz
size: 17.7L f3: 46hz
size: 21.2L f3: 43hz
f3: size: 24.8L f3: 41hz
size: 28.3L f3: 38hz
f3 ialah titik freq yg 3db kurang daripada reference freq. mksudnya, dbawah tu freq f3 akan turun dengan mndadak dn tdk kedengaran suda. contoh f3 = 43hz, freq d bawah 43hz akan turun dn tdk kuat suda. tapi yg kita tidak tau freq lepas tu 43hz macam mna pnghasilanya. mungkin akan jadi boomy atau lemas. tapi dari tu data sheet macam dia kasi highlight tu 43hz...klau sa jdi ko, sa ikut tu spec sja...hehe cara mau kira isipadu/volume guna ni site kira sndiri ikut kesesuaian ruang kreta masing2. yg penting isipadu dpt dekat2 dngan target isipadu

| bro Geeko, musik yg ko mo dingar tu perlu midbass power.
karas ka lembut tu kana pasti sebab box design nda cover dua2.
jadi berapa space n power ko ada?
kalau saya kasi ko box besar, teda space pla ko nanti. |

bro, Qtc 0.95 ni kira keras betul ni. ko akan dapat peaky response d upper range of the sub-bass. 1 cu.ft box ni kira kici & akan perlu amp power yg kuat. |

| ko kn guna tu amp sementara sja...nanti ko beli amp untuk tu sub ok suda tu.Qtc 0.707 slalu untuk yg seimbang la bunyinya...teda peak d mana2...tpi untuk sub ko kena la besar smpai 3.6 cu.ft untuk dpt macam tu punya response.tdk pun buli juga ko sumbat bnyak2 tu polly fill.kapas2 putih dlm bantal tu. rsanya ko akan tukar juga tu pegi sub yg besar sikit nanti...tpi smntara ni pkai ja pa yg ada ba. |

Qtc 0.707 ni bukan juga ideal pasal ni theoretical flat response in anechoic chamber. Dalam korita, cabin gain berubah dari korita lain ke yg lain. Ko simpan Qtc 0.707 pun ko nda akan dapat flat response. sebab tu saya main port kasi main bass response. Jadi saya main port tuning ikut apa musik dia suka. saya tanya si geeko pasal amp power dia sebab saya mao kasi max. spl pakai efficiency. ini masalah sealed box, nda efficient tapi bass response nda berapa peaky. |
