First topic message reminder :

Lets talk about anything and everything about sq(Sound Quality) setup here... cheers and have a nice day. Very Happy

WELCOME TO THE SQ WORLD welcome

What is SQ?
There's
a misunderstanding that SQ(Sound Quality) is a system that can't play
loud. Stock system also can't play loud but that's far from a real SQ
system. So what is Sound Quality? SQ is that aspect of a sound system,
which
encompasses all of the performance factors which give the system the
ability to re-produce an accurate and life-like rendition of the
original recording as perfectly as possible. It includes factors such
as tonality, ambient, subtle nuance, system gain structure, dynamics,
transient response, and the list goes on and on. SQ is a combination of
all these technical factors as well as proper speaker placement and
proper system design. When a system is said to have perfect SQ, it
generates the most accurate sound possible, with a sense of musical
realism that gives the listener the impression that they "hear" a
live performance right in front of them, as if the listener was in the
audience watching the actual performers on an actual stage. Now, to get
this realistic musical "sound stage" in a car, it takes careful
system planning, speaker placement, and tuning.

hehe sbb c vicky ckp guy from sabah/swk bought it, siapa lg kalau bukan ko..msti la di respek, pure sq tu bro..rasa pulse bass ja kali, teda rasa macam ada mid2 sikit di subwoofer..hi quality bass kalau g2 bro

hehe, kamu tt la dulu final, lum tau kalau dpt datang ni

oh..vicky ada cakap macam tu pula di icehifi.

aku pun sebenarnya tidak tau pun sub ni bagus betul.time aku mencari sub utk kasi ganti mohawk aku, nampak si vicky ni jual sub sq..yg menarik aku punya perhatian tu sub jenis shallow (3 inci jak ka tebal sub tu) , jadi bolehlah buat enclosure yg kecil..jimat ruang bonet hohoho.

klau kami ja TT kurang anjakan paradigma ba...hoho

nizam: bila ko ckp ja 10" sub sa teringat juga tu phase 10".hehe cuba ko search d internet brapa liter tu sub perlu.tdk pun cari manual tu sub.slalu ada tu.comp set ada suda ka?

hahaha.. kadaps. sy agak2 jak pun tadi. xda sy terbaca sabah/sarawak yang beli. tapikan.. dulu sy pun mau beli.. tapi.. internet cakap 1.3 cu.ft. yang ngam. kamu ingat ka post awal2 sy ada cakap dengan c rudy yang ahseng buka diyma? tu phase la sy p cek.. search diyma la. banyak 2 info ttg phase..

hehe...bah cepat2 cari info, pasang semua, pasang p80 fuh jd suda sq...tp bass nda boom boom chak la..component dia ada udah tu....'momo' kan? hehe

aku terjumpa manual, tapi utk aliante black limited (design macam sama jak)

utk 10 inci

sealed = 18 liters
bassreflex = 37 liters

boi, tu 1.3 cubic feet tu berapa besar yak? sealed atau ported?

nizam ko guna ni calculator http://www.the12volt.com/caraudio/boxcalcs.asp ko draft2 la rupa kotak sub ko.pas tu baru bikin. yg penting volume ngam la

btw 1.3cuft mau 37 liter owh.besar juga tu

aiya.. lupa oo.. tanya rudy.. sealed kali kan 1.3 cu.ft. rudy? tapi besar oo.. sama macam c rudy punya..

alamak pian, pening pula aku tengok calculator tu..dahlah aku ni zero knowledge kalau mo bikin box


oh..kalau 1.3 cu.ft tu = 37 liters, kira ported box la tu kan?

sub ni paling ngam pakai ported box yak

aku punya lebih kurang 1.3 la..wah besar juga kotak dia mau sekadar sub 10', sub 10 slalunya 0.75, tp tdk semestinya...cuba kita cek lg skali tuk tu aliante

ikut manual tu ckp kalau ported 37 liters, sealed 18 liters.hum, mungkin ada juga logiknya..so boi ckp yg direcommend tu ported box. cuma macam kau cakaplah rudy, besar juga box utk 10 inci ni..

rms sub ni 400 watts tidak bolehlah amp sedia ada saya angkat ni..adoi..

cuba ko cek you tube, org pakai phase 10' 17liters..alala besar juga power dia, 4ohm ka? kalau bleh jgn setengah lebih rendah dari sub la (sub 400w, amp 200w),kalau kurang sikit ndapa

kecil sikit dari spec yg itu manual cakap (18 liters)..rasanya memang sealed box juga ni, kalau ported box besar betul..hilang dah tujuan saya beli ni sub kalau box dia besar hohoho walaupun kena recommend 37 liters..

yup 4 ohms, amp saya ni lupa dah berapa, 200 atau 400 watt max..berapa jaklah rms dia tu..memang tak dapat angkat ni sub..ui, sub 10 inci jak ni, 400 watts rms

voice coil pun boleh tahan besarnya...125mm

ya seharusnya sealed n kecil la....wah kalauu 400w max tu rms nya macam rendah ja tu

sebenarnya 2la pasal sy xjadi amek 2 sub. kotak dia yang sandi.. xpaba. ko maen sealed jak. tapi kalau xsilap memang 10' dia = 12' sub laen. 1cuft = 12' sub biasa. tapi phase 1cuft = 10' punya..

apa bleh buat la, tu sub bgus suda...kotak pula besar...ba antam ja, bleh ba tu, think out of the box, tdk semestinya ikut ukuran yg di bagi..

hehe ni crita phase panjang pula

anyway, saya paste lah dari manual sheet ni sub

RMS (Pn) = 350watts (kurang sikit dari spec manual aliante black limited)
Peak (Pp) = 800watts
diameter = 266mm
depth = 75mm
magnet weight = 1.9kg
Frequency range = 20 - 300 Hz
Impedance (Zn) = 4 ohms
dc resistance (Re) = 3.2 ohms
resonant freq (fs) = 23.0 Hz
mechanical Q factor (Qms) = 3.608
Electrical Q Factor (Qes) = 0.456
Total Q factor (Qts) = 0.405
Equivalent air volume (vas) = 37.0
compliance (Cms) = tak dpt aku faham, tulisan tangan
moving mass (mms) = 0.163kg
voice coil diameter = 125mm
force factor (bxl) = tidak tau haha
linear excursion (xmas) = sama da 4 atau 7 mm+-
sensitivity = 90db

ada pula spec ported box

ported enclosure volume (vb) = 13.74 dm3
enclosure Q factor (Ql) = 5.00
enclosure tuning (Fb) = 44 Hz
port diameter (Vd) = 86mm
Port length (Vl) = 583mm

adoi, banyak yg saya tidak faham hohoho..harap dapat bantu design box ikut spec ni

hehe ni crita phase panjang pula

hahaha..kita tutuplah topik sub ni, buka cerita lain..p80 pula hohoho

hehe bah, tu kotak ko buat yg ngam tuk kreta ko ok suda tu, dia bg spec tu tuk yg general ja/bunyi sebelum masuk ke kereta, kreta kita lain2 jd boleh buat ukuran sendiri, yg penting tdk trlampau besar atau kecil...aku punya pun 1.0cuft di rekomen, tp aku pg antam 1.3cuft hehe..

bah crita pasal p80? apa soalan spot hehehe..HU yg bagus tuk 2 way..senang di fahami..murah lg tu rm700 ja hehehehe (masuk spec ka ni harga hehe)

18L = 0.636 cuft
sbnarnya tu calculator untuk mengagak sja ba.hehe ko letak ja pnjang lebar tinggi tu smpai ko dpt tu 0.636cuft.

Interior Volume (ukuran dalam)
Width 16
Height 14
Depth 5
= 0.64815 cuft

P9 macam mana bro?senang difahami juga ka?

thanks pian.memang tak berapa faham mo guna calculator tu anyway, harap kau juga hehehe...saya try figure kau bagi dalam calc tu dapat 0.29167 cuft jak memang fail betul hohoho

so inner size box tu 5 inci depth, tebal kayu tu dalam 1 inci so plus minus dlm 7-8 inci lah depth bila siap nanti..betul ka?

yalo.. murah oo p80 700. market sekarang dalam 900 la paling murah. Cuba try test survay dulu..
