I know, Im fixing the edges... i gotta go get certain sand paper and i painted the top of the screws black, the holes are fixed too... scion emblem is straight now... it was just pretty much taped on...

And the subs are actually alot louder than i thought they would be and the sound is very clear... those subs are great for the price...

 

just refering to spl, your limited in a sealed box.. personal preference of ported. but i like cars that can knock your head off.

 

dude, wtf are you talking about "he can't go beefier, its a sealed box."??? What does having a sealed enclosure have to do with getting better subs???

If anything, upgrading to a "beefier" sub may require more airspace, but he looks to have Plenty in that enclosure.

And i've seen plenty of sealed enclosures outplay ported/vented in both Sq AND SPL. With 2 12's in a tc hatch, you can get pretty darn close to blowing someones head up. if they're nice beefy comp grade speakers.

 

i disagree, the airspace required for a ported box is huge for 2 12's alone (most speakers). grant it in theory you can put any size 12 inch sub in that box, can face the woofer into the box for looks. in SQ , sealed can out perform ported, in SPL, a sealed vs a ported with same equipment at same power there is no question that a ported would take it hands down.

 

my 12" and the box is barely to spec

 

exactly. ported boxes are much bigger, and are much more capable of moving alot of air. now there are small box subs like L7's so on so forth, but their boxes are still fairly large in comparison to sealed.

 

look at even the 8w7 in a H.O. box it would be the same size as my box above. 8" sub box as huge as mines!!

 

Well i know there is plenty of air space in the enclosure i have right now... If i did get new subs im sure i would have enough... if i didnt i could add a ring or two around the hole for the sub

 

not as easy as adding a ring or 2 around the hole ..

 

why make a huge box for 2 12" when you can use multiple small drivers to destroy the spl 2 12"s would make. the big ported box for big spl is only one impractical way for spl.

 

your joking right? lets see, record breaking cars, the green van who hit 180+ with 9 15's in an open ported box. the box sat bottom to top in the passenger seat and the port was the entire back of the box. but your right, multiple small speakers right?

 

spl is directly related to 2 thing xmax and surface area. the more surface area the better. at those levels there are no small drivers that can handle those power levels. at this level 3 10s would have a higher spl than 2 12s in a big box. as long as they have equal excursion and power handling capabilities. besides 9 15s pretty much proves what i'm saying, that is a lot of surface area moving.

 

ok keep one thing in mind, the size of the tc's hatch is very small. i have a ported built to spec for rockford t1's and it takes up my entire hatch. try to fit 3 10's with a spec box, its not gonna happen. and as far as spl is directly related to amount of cone yes, and amount of air moved.. so your saying 3 10's in a sealed will have more spl then 2 12's in a ported with same power, wont happen. 3 10s have more cone surface, 2 12's have more power per speaker (keep in mind this is off the same amp each car) so they in turn will move more, and have free flowing air to generate high spl levels.

 

12s do not handle more power necesarily with a lot of higher end speakers their 10s have the same xmax and power handling as the 12s. and 10s need a lot less air space to make max spl and still sound musical. also have you seen mandos 32 small speakers in the hatch that ain't just for looks. hes gonna be able to blow your eardrums out with a relativly small amont of power

 

im not saying 12 handle more power, your completely missing the point. lemme break it down. we take 1 rockford bd1000 ok? lets say it puts out 1000 watts..
2 12's theoritically will be getting 500 watts each off that amp correct?
3 10's will theoritically be getting 333 watts each off the same amp correct?
This is my point, same setup, more smaller speakers. This all goes back to the size of our trunk and the amount of space we have to work with. the 3 10's will have more cone space, but will have to compensate for the lack of air space. The 2 12's will move less cone space, but will move more (500 watts as opposed to 333) and there wont be an air space issue.

 

and what i'm saying is if those 3 10s hit xmax at 330 watts its quite possible for them to be louder than those 2 12s

 

i'm starting to think that we would need to do a controlled experiment with both of us there to settle this conversation. haha

 

it would have to be an experiment. youve had your experiences, ive had mine. remember i keep saying im new at turbos in most of my forums that ive posted in, well i started with stereos over 8 years ago . been working with them for a very long time, but ive been on the spl side of the house. as far as sound quality, thats beyond me, for as far as spl i can get a system setup to knock heads off..

 

i have had 10 years experience and would love to do a build off with you. btw i have an orion 1100 watts rms at 1 ohm pushing 2 orion hp10s and 2 orion 100 wattsx2 at 2 ohms pushing infinity perfect components in the back and the front. whats your set up (not bragging just curious).

 

pictures of my setup is on one of the previous pages, currently running a bd1500 @ 2ohm pushing 2 rf t1 4ohm dvc. click my weblink to check out old stereo installs, the one in the geo holds state record for M3 class. that was my sealed box experience, but it was also 4 15's . i dont have an amp to my highs yet, im trying to decide how im going to install it. the box came out alittle bigger then i expected and i was gonna run an 800s rockford colormatch with a link, but there is no way it would fit. so im thinking im gonna mount it on the side of the box, but i gotta be able to slide the box onto the backs of the seats in case i get a flat, so well see how that goes, i got 6 months to decide. im still breaking the speakers in, i have about 13 hours left to do on them, but its feeling like im hitting around 143 which is really good considering i have the amp 1/3 the way up. cant wait to turn the beast all the way up.
