w/c is better

one thing, SQ is a very subjective aspect. to each his own opinion, regardless the manner SQ can be reached or doen, as long as it's an opinion, it may help another in learning about audio.

walang kinalaman ang size ng subwoofer sa sq. at kung sq ka, 1 lang pwede na. ang dapat mong tignan yun brand ng subwoofer mismo at yun motor construction nya.

teka.. naabutan ba ng 8inch sub ang low frequency range ng 15inch sub?

ang findings namin iba iba ren ang sound characteristics ng varrying size ng sub. casse na test na namin yan eh. .same HU, same amp, same seps, same car, same music, at kung ano anopang the same.. inibalang namin ang size ng sub. pati nga ported and seald enclosures tinest namin basta lahat the same. eh, pero bigay ko sainyo yun conclusion ng comarison ng 8inch at 15inch sub.. kasi medyo malayo na size nila. ang nalaman namin. medyo masmabilis ang hataw ng 8inch sub compara sa 15inch sub, ang kalabasan medyo 'matigas' or 'mabilis' ang dating.. medyo maganda pakingan pag kasabay yun midbass kasi parang sakop nilang ang buong midbass frequesncies... dun naman sa 15inch sub.. medyo 'malambot 'ang tunog. parang humb, tapos kuhang kuha ang low frequency, pag mababa na yun freq. mas lumalambot. parang sinasalo ka ng subsonic wave. hehe.

so bali kung SQ habol mo at medyo type mo ang rockmusic okaya manga electronic music siguro mas nababagay saiyo ang manga 8inch or 10inch sub.pag medyo ambiant ang dating o kaya jazz na medyo emphasis ang bass guitar, maganda ren and manga 12inch or 15inch. kung gusto mo pa nga 18 o kaya 34inch eh hahahaha.

sa tingin ko tama si glennster.

mas malaking cone area means more air being pushed. sa mas madaming pushed air nag dedevelop ang subsonic frequncies.(na mas malalim) kaya masdan nyo pag malayo kayo sa sub mas nararamdam mo yun low frequency kasi nakaka pagtravel sya ng malayo. eh pag mas malaking gamit and gumagalaw siempre babagal sya ng konti compara sa mas maliit diba?... tapos lumalaban pa yan sa standing air. kaya siguro ang bilis ng hataw ng 8inch sub. mas konti lang kasi tinutulak nun. opinion ko lang ito. hinde ako physics major haha

good day manga peeps

actually, bass waves or sine waves get louder especially lower freqs as it hits or bounces off. this phenomenon is called "transfer function". notice that in a front firing sub, towards the cabin. as you open the trunk and go farther from the car, the bass gets louder. it bounces of the front cabin and is released thru openind the tunk. if it was rear firing, it hits the trunk and as it bounces of it towards the cabin area it gets louder. this is why in most competitions, notice where the mic is put? it is in the front dash because this is the 'sweet' spot of the car. its not because more air is pushed. notice how a miata's cabin with an 8 inch sub be louder than in a ford excursion? it is because of the transfer function and not because more air is being pushed. also, kung nahuhuli man yun 8 sa 12 of the same sub baka the sub was not meant to play fast, meaning its not as precise or the motor construction was made for a different application. ex 10 solobaric at 12 solobaric. pero pag 10inch w7 at 13w7 kahit anong beats pwede. this is one reason why when choosing a sub based on what type of music you listen to, it's best to check out its motor construction and the application is which is was designed for rather than thru the size of the woofer.

ang galing ng explanation mo tungkol dyan sa competition. salamat. pero ang miata maliit ang cabin space nya, compara sa excursion kaya madali icompress ang hangin. yan ang labanan sa SPL kaya ideal dyan ang maliit na hatchback type na cotse. nakuha ko na explanation mo pero medyo nag cacontradition ka ng conte .. sa sagot mo kay glennster, parang nagulat ka na may nag sabi na iba ang excursion speed ng different size sub. pero ngayon bumawi ka at sabi mo "kung nahuhuli man yun 8 sa 12 of the same sub baka the sub was not meant to play fast, meaning its not as precise or the motor construction was made for a different application." so kung bumili ako ng brand x sub na "not meant to play fast" eh di iba ang excursion speed ng different size subs ng brand x? sa tingin ko iiba parin ang speed eh. also, nag comparison test kapala ng 10inch and 12 inch solobric. ok yan ah paano yan? same car, same amp, same enclosure type same lahat?? tapos na conclude mo na iba ang excursion speed ng 10inch at 12inch. tapos nag comparison ka rin ng 10inch at 12inch W7? wow. ano yan? same car, same amp, same enclosure blah blah blah? gets mo ba? wag kang mainis at ganyan ang impression ng tao sa pag salita mo. ngayon paano yan? so umamin ka na iba ren pala ang excursion speed ng iba ibang sub size noh? eh di, tama pala si glennster! kasi parang kinocontra mo eh. peace tayo sister este brother katuwahan lang.

yes, we did an install here at my friends shop on the 10w7 and 12w7. since the customer was not in a hurry we, tried and tested it using the same parameters. the reason why it gets louder is a small cabin space is because the sine waves takes less time to travel from one point to the other and as sine waves bounce it gets louder.

kakalito naman kayo masyado technical

[teknine]

so sinasabi mo ay kung parehong pareho ang 10inch at 12inch? ang kaibahan lang nila size at power output? hanep eh di patas lang pala ang 10inch sa 12inch. ma text ko nga si pareng mannville smith ng JL kung ano say nya. hanep! ano nga pala shop at contact ng "friend" mo? may manga tanong lang ako sakanya baka bumili ako ng equipment sakanya eh salamat in advance

[teknine]

so paano yun kicker? siguro naman nag test ren kayo diba? or speculation mo lang yun? facts naman dyan thenks

[bloodline]

yup we did it to in a vw jetta.

[teknine]

oh ano na contact number ng friend mo? yun may shop mukang astig kasi ang sinasabi mo gusto ko lang ng info baka dun ako bumil. pwede ba? o baka mabuking ka lang. ala stir kasi dating eh. siguro na bara ka lang. kaya mo yan chong. sige pa ng sige
