12" or 15" for trunk?

[TintedUp 0]

I want to do the package deal for the xcon and the sundown 1500.

This is a daily driver (300C) so I obviously want sound quality (which is why I assume the xcon is a good choice). Although my main focus is to hit the lows with some really strong output, because I listen to rap. I don't want to fold the seats down either, but there is a stock 8" in the back that I'm going to take out, which should help the sound in the cab.

There is enough space in the trunk to build the optimal sealed or ported enclosure for the 12" and but only for the optimal sealed for the 15"

So my questions are.

- is this too much for the trunk, or too little (or the best option?)

- should I run a single 12" or 15"

- will I need to do the big 3 for this setup?

- should I build a sealed or ported enclosure

- (if I build a sealed enclosure how will it sound in the cab)

Also, I have been reading the deadening thread, should I go with SDS for this?

Thanks,

Sorry if there is a similar topic, I couldn't find one addressing my concerns.

The sealed enclosure will have a flatter response then ported (unless you tuned extremely low).

If you did tune extremely low and used the 12", the 15" in a sealed optimal would likely yield more output, at least in an open environment, with a trunk

The Big 3 is simple and cheap to do and helps if your stock wiring and grounds are wimpy, so why not do it.

The owner of SDS, Don, is an awesome guy. Shoot him an email with your vehicle, budget, and he can recommend approx how much product you'll need and how to apply it. He won't sell you more then you need, at least not intentionally.

sealed or ported is a preference.. like jiggly or perky.IMO

i would do a 15'' ported seems how you listen to rap.

big 3 allways

and second skin!

reason for edit.. i got distracted thinking about jigglies

In a 300 c I'd think you could get a ported 15 in there all day and have some really good out put

This was my first thought.

honestly I like both

But back on topic, I dont see why you cant fit a 15" ported enclosure in there.

Is a ported 15" xcon gonna be too much?, I want to go as loud as I can without breaking anything.

[Freshh 11]

We don't know what "too much" is to you, to some of us it may not be enough, while to others it might be "too much".

No we can't tell you how loud you'll be, at all.

If you're worried it'll be to loud this is what I'd do... Buy the 15" xcon, make the optimal sized sealed enclosure, and go from there, if it's enough for you, woot! If not, port that mo-fo!

[jcarter1885 995]

Too much what? Flip a coin if you dont know which one to go with, either decide if you want a 12" or 15" it shouldnt be that hard of a decision. The 15" will have more output that a 12" sub of the same model due to the 15" having more cone area.

Sorry, I meant will the ported 15" shake my trunk lid apart, I was just kinda asking if anyone has done or seen this, and if it was just absurdly shaking the trunk lid. If its manageable then I'm not worried.

[MikeMartel 64]

I dont think youll be breaking anything in your car with a single 15.

[jcarter1885 995]

You are not getting a spl sub and trying to be all out loud so why are you worried about tearing things up in your car, your making this more difficult then it should be honestly. If you face the sub and port up facing the trunk lid then yes it may have potential to rattle the trunk lid but will it rip it apart, no.

Alright, Thanks everyone. I was just making sure, because I can only afford to do this once. haha

What is the "Rule of thumb" regarding a 12" xcon and a 15" xcon? Say both subs are tuned to 32Hz and are in their "optimal" ported enclosure. Should you expect the 15" to be twice as loud? We tlaking 3dB, 6dB, or even 10dB?

I am facing this same dilemma where my old accord can easily fit a single ported 15" xcon, but in a year or so I plan on getting a new car with a smaller trunk. The new cars trunk will easily fit the 12", but the 15" will be a bit tighter fit and I am debating if it will be worth it.

All things equal the 15" has the potential for approximately 4.5db more output. In subbass audibly twice as loud is around a 6db difference, so it wouldn't sound twice as loud but it would definitely be noticeably louder.

But it also depends on what you mean by a "bit tighter fit". It's possible to try to stuff too much sub and enclosure into a trunk, making the effective difference between the two options much less. If it would comfortably fit the 15" in a proper enclosure I would say go for the 15". If realistically the 15" and enclosure is just too big for the space then you would be better off going with the 12".

Ok, I'm stealing that for my signature.

Thanks for the reply. My brain is telling me to go with the 12", but the bass head in me is telling me to get the 15".

Are the models available anywhere for bassbox pro? I noticed that some of the parameters arent available on the site for Le etc.

I dont think youll be breaking anything in your car with a single 15.

It's a Chrysler. . . .

For the Xcon's? They have sufficient T/S parameters on the website to model enclosures. You don't need Le to model an enclosure. If the program you are using requires it be input, just toss something in like 2mH.

[Tirefryr 1,742]

It doesn't. BB has no use for inductance at all. Hell, it's only real point is a cut sheet. It models poorly.

What would be louder? Having a 12" in the optimal ported enclosure (2.6ish cubes), or putting the 15" in a 3.25-3.5ish cube enclosure? The optimal for the 15 is 4 cubes. I will be using a saz-1500 to power the subs. I am tihnking the 12 with the larger enclosure would be better with 1500 watts as opposed to the 15 with an enclosure a bit smaller then suggested.
