one 15in sub in a civic coupe?

[syvikraicer]

would it be wise to put one 15in sub in a civic coupe? or would it sound better with like two 12s?

[dak4.7]

2 12's is more surface area than a single 15, and more often than not, will get louder, that is if you're talking about the same type of subs.

Depends on what you're goin for really. 2 12's will also take up a bit more physical space, and will require more power than a single 15 in most cases (again, comparing a 12 and 15 of the same type), so everything comes at a sacrifice.

Me, I don't think I'll ever use a 15, 12 is the biggest I'll go, more likely 10's though, but then I'm a pure sound quality person, loud is nothing to me, so that just goes right back to the questoin, what do you want it to sound like?

2 12s will sound better

[Tre']

I have one 15 now. My last subs were 2 12" Image Dynamics. Before that I had 2 10" Kicker Impulses. The two 10s sounded the best to me. Just depends on what you want.

[akaPsyco™]

I did 1 15" hx2 punch...then went to 2 12" he2 and the were louder...but plaied a different sound....I like the 15 for the sound that it made...but I couldn't get the spl I wanted...I like how the 15 would move the air...

[Slim ThuG]

get 2 IDMAX 12s...egg had some of those...and they fuckin pounded:thumb:

because??:confused:

[syvikraicer]

well i want some thump but nothing too loud...i was wondering if the thump of one 15 would equal to or be close to two twelves....i want to conserve space

[Tre']

Depends on what kind of sub and how much power you give it. I've heard a system with one 15 that would rattle the dishes inside our house when it passed by.

im a prime example, my one 15 hits harder than 2 12's ever will, and if you want a 15, im sellin 2 of em

[dak4.7]

well, you could get you three small enclosure 10's, and probly be easily as loud as 2 12's and definitely a single 15, and you could make or get made a box that contains all three in seperate chambers that maybe fits up under your rear deck, leaving you like half your trunk or more.

Plus, 3 10's should be a lot less "muddy" than the *average* 15

:roflmao: LOL...we're coming the same models aren't we? except they are just different size right?:roflmao:

Of course-- comparing different models is like domestics vs. imports all over again :)

Even with subs that I don't think sound good, (not like an only-sq sub, i just mean average market subs) the 15's always lack SQ compared to the 10 of the same model.

I bet I've told you this before, but your name looks DAMN familiar...you ever posted on elite car audio?

the diameter of the sub has nothing to do with transient response/frequency response. ;)

i posted on ECA a few times (like 5 times?LOL). i stopped because the server wouldn't let me enter the forums. each time i wanted to do something, it made me log in. after i did log in, it brings me back to the beginning page. then i click a forum and i had to log in again. i just gave up:P

[dak4.7]

Yeah that was a problem they had a while back...I think it still does it actually, I dont know.

Regardless, every same type comparison of a 10 and a 15 I've heard, the 10 sounded better.

in most cases, people don't put their 15's in the right box. they usually go with the manufactor's spec, in which case will satisfy the "average joe". box size GREATLY affect transient response. what if we putted a 10" (recommended 1.0 cubic feet) in a 1.0 cubic feet and the same sub in a 1.5 cubic feet? as you know, the qtc for the 1.5 cube is lower, resulting in a much flatter response (wonder why small boxes are boomy?). now what if we did the same with the 15"? what if we also give the sub the same alignment? with the same qtc as the 10" in the 1.5 cubic feet, it should virtually sound the SAME, except the 15 would be louder.

i have own many 15's (E15K, RE SE, etc..) and i say they do very well in SQ comps. many more people are taking the 15" route nowadays after they have been seperated from myths from facts. subs that has poor response have either one of the following:

1) improper box
2) high inductance

unfortunately we can't change the Le, but we can change the box size. it makes a world of a difference, and i know everyone here knows that.;)

[dak4.7]

Yeah, cuz everyone here knows what qtc IS :hit: :roflmao:

I've never owned one, maybe in one of my own boxes it would sound better. I dunno, I'm not a heavy pass person, a 10 or 12 is usually enough for me. Maybe I'll have to pick up an id max16 and prove you right :)

[GSteg]

a 12" is also enough for me. but when i bought my sub, i said to myself.."hell..why not spend $10 more and get way more Vd, SPL, etc." who knows...in the future, that extra cone area might help out when someone wants to compete with me.:thumb:

[syvikraicer]

if i do get one 15in sub...would it be possible to mount the sub facing up in the spare tire area while maintaining a good sound quality? again conserving space and it just looks pimp :D

this is in a 99 civic coupe

I see a new movie idea..

Air Movers--starring vin diesel, paul walker, and some hot chicks

"It don't matter if your sealed or bandpass, numbers are numbers!"

"Lengthen the port and lower the tuning freq. and you'll be pushing 170's"

"Now me and the mad scientist gotta rip apart the enclosure and resolder the tinsel leads you fried!"

:cool:

Yes ladies...I'm single :P

usually I think the differences in sound qual. with nothing changing except the direction the sub faces is pretty minimal.

I really would like to know...haven't heard a single 15 hit hard than me in this area...

can i be the first to let you experience a 15" hitting harder than your 2 12's? LOL
:roflmao:



i don't get when people say "15's hit harder than 12's" and such. louder? possibly, but i don't know about harder. kinda funny if you ask me. one of those voodoo myths floating around in the car audio world:thumbsdow

[dak4.7]

There's a shitload of voodoo myths in the audio world. JL for example :P

what does yours hit?...mine is in my sig...

[syvikraicer]

lets have a sound competition!! :thumb:

the single RE SE 15" hitted 151db on a termpro mic.

the single E15K hitted 147db on an audiocontrol mic (less power)

the Stroker 15" hitted 149db on a termpro mic

the 10W7 (yes its a 10" :( ) hitted 145db an audiocontrol mic (i know thats sad..)

pick your competitor :thumb:

and the 10 is bad ass....

i wished i had the 13W7 instead of the 10W7 though. i can't stand 10's..:(

Why? I'm hoping to get 3 10w7's soon. I dont see why a 13w7 would be any better.

more volume displacement:thumb:

instead of 3 10W7, get 2 12W7. 2 12W7 has more total linear displacement than 3 10W7. who knows, you might save money:) and you'll definitely save weight

I'm thinking three 10's would giveyou 30 inches of bass, where two 12's would give you 24 inches. What is linear displacement?

you can't just add diameters. lol. if that was true, then 2 10s (in your case 20") is more than a 15" (in your case 15") when really a single 15" has more cone area than 2 10s of the same model.

linear displacement is xmax times Sd. its the amount of air being pushed at xmax. :) more air being pushed, more SPL. 2 12W7 would have more displacement than 3 10W7

Sd is is the surface area right? Trying to get that straight, my t/s spec reading days are over, seein as how I never fully learned them to begin with, then kinda backed out of audio for a while.

[GSteg]

yup. Sd is the effective cone area.
