from what i see there.its just like takin my 6ackseat out. whats makes the differance of how the air will travel thru the port vs a 6ox in the trunk wit it wide open?is it a sealed 6ox aimed at the port?is the port attached to the port?or is thrunk sealed so tight that the air has no choice but to come thru the port?

OMFG....

Different types of blowthrus how i see it.just open up the rear deck,

i think he wants info on 4th and 6th order bandpasses, but thinks they are called blowthroughs

Ok let me sum it up.

Bandpass enclosure is (2) Chambers

4th order has (1) Sealed Chamber & (1) Ported Chamber. Bigger than a rec. sealed or ported enclosure for the driver (sub) due to it being 2 chambers BUT when done right..will give you "the best bang for your buck", giving you the characteristics of both sealed & ported boxes.

6th order has (2) Ported Chambers. Bigger than a rec. sealed or ported enclosure for the driver (sub) due to it being 2 chambers and usually a little bigger than 4th Order Bandpasses, This is usually recommended for subs designed for this application because it's offers no woofer/cone protection & IMO most subs will blow due to not being able to handle power in this application BUT when done right, this will give you outstanding low bass.


Most bandpass boxes you see are 4th order. Easier to design, more speaker friendly and better overall performance IMO.


BLOWTHRU's...


Around here, a blowthru to is opening up the rear seat, putting a "mouth" (big port) on the back of the seat and just letting the bass flow thru. Usually the box is faced towards the front of the car. Most cars have the box enclosed all the way to the backseat so ALL the bass goes in the cabin.
I've seen where people are just opening up the seat and thats it. Thats not a blowthru, thats just opening up the rear seat which still allows alot of bass to come thru.

An enclosure designed as a blowthru is what I mentioned as being a box that is enclosed, connected to the cabin. So all the bass goes straight in the cabin. usually it's thru the rear arm rest in the backseats or rear deck.

Pitch in anyone with REAL KNOWLEDGE on this because I don't feel like going more in depth with this

did i mention i have a blowthrough in my car?

i can't stop fucking laughing

just because i'm bored, yall definition of a blowthrough imo seems to just be a cleaner way (dressed up way) of taking the back seat out

Naw homey, you thinkn about that pic you seen with that brown fabric shit from 941.

Thats whats I said above.

Thats blowthru also whether it's admitted or not, it's just not a blowthru seat to enclosure setup that usually seen on car audio sites. Serves same purpose. But around here our blowthru enclosure's get built to the backseat with a neck/port.

941 on their own with facing a box to a port opening. But either way it works and they got some loud shit.

But our backseats are usually full of mids/highs so we dont care for backseats

This an old one, this bitch here.......shittin loud with (4) Earthquake 12's, box built to the backseat, mids/highs everywhere

i see what you are saying, but from other pics i have seen, what the difference in what the 941 is doing and just taking the back seat out and facing the subs forward through the opening

care to share? or a drawing. all i see is fancy walls. do the speakers gotta aim at port.is a vented 6ox in the trunk considered 6lowthru?


shit.dat shit funny 6ut dats real talk.


dats what im seeing.







so i i take the 8 10's point them up twards trunk.with a vent running straight dwn the center with a vent in my seat.is dat a 6low thru? or do i need the speaker 6uilt midway wit a 6andpass style cover over em wit ports pointed at the vent in my seat? some1 draw dat shit out

Yea I knew what you were thinking, thats why I tried to explain it.

hey i c all these suv's an 6ig cars.do u have anything major like dat wit a so called 6low thru or trunk setup?

I was going to do (8) 10's in my cutty.

The way to do a blowthru with this is to build on that hump. Cut a port in the backseat, line it with wood *mouth of port" extend that to the box.

The box will be sealed facing up, but you will have a covering panel so you cant see the subs that extends to the port. so its an enclosed box the extends all the way to the backseat.

Like this. F yall hating on my paint skills. Im tired ***Thats one big box with the sub box inside.***

question since thats not really a bandpass setup, but does that affect the way bass sound as far as responses goes in hz

dats what da fuck im talkin 6out.gd look.
so i need a seal incloser over my su6s to throw the air out my rear seat. so no vent is required on the 6ox that will 6e holding my su6s?or is it a vent to release air into top 6ox to mouth?

can some1 magnify this.
aight these are the 3 questions.
1.green arrows are seal 6ouncing of top cover NO vent
2.6lue arrows vent in middle 6ouncing off the top lid thru vent
3.yellow puffs coming thru a 6ottom vent from side of 6ox shooting out sind vent to mouth.
which 1 will hit harder an which 1 is correct?thanx in advance.that pi 6lown up will answer all my questions.

what da inverted su6?is dat a 150-60 setup?

lmao, man honestly your not gonna get a 150-160 setup in that cutty, unless your building a wall thats the easiest way, even if you did a blowthrough it's not that simple, loud and pressure is two different things

Im going to post 2 videos,



This is my homie, he got (2) Audioque HDC3 10s and a Audioque 3500d amp pushing them in the truck. No blowthrough, everything inside the cabin. Did a 146.3 on the TL in the kick I believe. Amp was set to put out only around 1800w. That shit was loud, real damn loud. Doors flexing, back wall of the truck jumping, loud.




At the same show, met this dude, and demoed his setup in his F150, (4) Digital Designs 9515s in a wall tuned to 38hz. Loudest shit I have heard in a very long time, does mid 150s on the TL on music, and burped a 159.something at the show. Thats his everyday car, I told him hes crazy.

Believe me, you dont want a 150s car for your daily, plus other than a wall, its not going to happen in the cutlass, not the right car for it.

not to mention it's a t-top

You know what, I think the same, Its damn near a bandpass besides not having a "loading wall". I've seen claimed bandpasses withouth the loading wall (usually v-shaped boxes to the backseat) but then learning from other big audio heads, they said it all acts the same, some people just go to far and classify things beyond whats needed. Cus looking at PWK blowthru bandpasses, some people say thats not bandpass cus I dont see a loading wall, others say different.

But that box will definetly hit all around notes with the sealed box, that "tunnel" to the backseat will amplify the sound a bit I believe but thats how its done around here. Thats what I wanted to do in my old cutty.



Nice

I thought you had done died on me .




You're doing (8) 10's SEALED i thought? NO vent for a sealed box. Only vent it in the backseat.

yeah. if i got that route.6ut im askin as tru 6low thru.which way is the 6est. 1 2or 3?

Sealed. No Vent!!! Only Vent is the one in the backseat. Not the box

You can't do 8 10's in a true blowthrough. But go ahead and open up the rear deck.

aight good shit.i guess ill c how it goes.lol


oh o.what?




well whats a tru 6lowthru?

ah oh?

i told you what setup to do, so i'm just being entertain from now on

Yes you can, just not in a trunk.

I told em to open up the rear deck, or put a big port in the seat but you see how this is going.

what yall talkin bout open up the rear deck?i thought im was gone 6uild a 6lowthru wit my trunk?i want da 6lowthru.what i gotta do 2 make the 6low thru?

your a idiot

x2

lol holy shit....smh

you want a true blowthrough?

go buy a truck

dude told you once already what to fucking do now do exactly what this illustrates like he told you in plain clear simple ass english, shit is not rocket science

:BIG FACEPALM:

Im done with this.

x2 we have told him damn near every possible setupt that would get that cutlass loud, we gave him a intrunk setup to work with, we gave him a blowthrough setup to work with, so fuck it

x2

shit i feel you.i was all good till caps came thru an said it aint a tru 6lowthru. so i asked how many speakers can i use. what da hell yall gettin so impatient for.lol im trynna have y shit 2gether.im a visual learner an since yall cant show me shit an trynna learn yalls way. da img i posted was a prime example. all i wantted 2 kno was 1 2 or 3 an how many 10 or 12s can i use?

read what audio avice said, you have everything you need to know

all my gbodys that ive had a blow thru in it has always been 4 12's....2 different style of boxes and speakers.....1 way was 4 across facin forward into the car wit a box and then a mouth (or opening) thru the backseat..like audio advice said..and then i had 4 wit 2 angled in kinda like a v shape cuz in my last car the trunk wasnt as wide so they v shaped wit a mouth on the front...but if you make to big or to small of a opening you gona eitha not have enough pressure com out or to much and be like a loose pussy juz pushing air and no pressure

now y you go and do that, you just asking for another 5 pages of dumb ass questions

True!

The arm rest is usually great place to use. If you can't use/dont have an arm rest, ports should be Wide(Length Wise) and Short(Height Wise)




I had to laugh out loud on this for real. You know it's coming!!!

lol.damn. so my question answered. so i shouldnt face my speakers towards da trunk.


naw.i aint even ask no dum6 questions for real.yall just aint answerin 2 da fullest. i tld yall i dnt understand all dat science stuff yall tallkin. all i need to hear is 4 12 facin up. or 8 10s facin up twards trunk or twards the mouth? an im done.

and you where saying, that picture exlains it all, even went enough and exlained it all to you

awww mayne.we 6een got past dat.im trynna figure out how many speakers is needed whats da max in can do in 10s or 12s. as far as goin sealed.
