will this box size work for a 15 inch type R? should it be smaller/tuned lower??

smaller and lower tune.

2.9 cubes, between 27-30hz

No.

Personal experience, and im SURE many other members on here will feel the same. The first box is a much better choice. IMO.

How bout this, build the box to the resonant frequency of the car. If you're not going to do that, then go by what the manufacture recommends. Don't try and guess different dimensions until you figure out what is supposedly good or after x amount of people figure out "this size is the best at this frequency."

Each ****in car is different, you can't say "this is better, than that." So unless you figure out what the resonant frequency of your car is, and then built it around that.

YOU nor I are correct. So you go eat a dick as well. //content.invisioncic.com/y282845/emoticons/wave.gif.002382ce7d7c19757ab945cc69819de1.gif

Over reaction much?

So I guess you either build a box around one peaking frequency or you do what the manufacturer says? That's pretty terrible logic. Why not build a box that suits your wants and needs? You said it yourself that each car is different so why would you listen to manufacturers that have no idea what you want or where it's going?

When you tune the enclosure to the reasonant frequency of your car, that becomes the pin-point at which the subwoofer will sound the loudest within that car (as well as having to do the least amount of work to get there). If you tune the enclosure to the exact resonant frequency of your car it will technically be louder than an enclosure that isn't. Basically, if the frequency is over the resonant frequency of your car it will be working against the car's natural flow, if it's under it will have to work harder. When its at the precise level (whatever it may be as all cars are different) it will be the loudest point in which it can and will possibly get because it won't have to work against or struggle to make whatever the natural resonance of the car is.

You're right, the manufacture isn't always correct. However, I've learned that if you don't do the whole resonant frequency thing if you don't have the tools to do so. To then built it to what the manufacture says or at least as close as you can.

Maybe 3.5 at 35hz is the ideal size for his car but who knows. What may have worked for 8 people on here may be completely wrong for his application.

Didn't mean to seem excited.

i have an SUV. The box will be sub up port back if that helps any

So what you're saying is to make the sub either as loud as you can at one frequency or just go with the manufacturer's recommendations? What if the user wants something completely different? What if they want something loud for everyday music but can still dig deep for some low stuff? Tuning to the resonant frequency would blow *** for that application. Many times, so would going with manufacturer recommendations. They almost always recommend enclosures that are either too small (to help on returns due to over driving the subs mechanically) or tuned too high (to satisfy the joe random who wants something loud and doesn't know anything about low end).

I would much rather build an enclosure to my needs and not what some random manufacturer tells me I should use. I will also not be building something to be a one note wonder.

Dude....

3.5 at 35hZ... Trust me.

not everybody has the means or the money to do this task...... there is nothing wrong with a pre-fab box if it sounds go to him...... your going deeper then the OG poster really wanted you to go

if all else fails do what alpine recomends for the sub

 

[wcarson8911 10+ year member]

im gonna go with the 3.5 at 35

So if the resonant frequency of someone's car is 65 hz, they should tune to that? Yeah, that'll work out GREAT for a daily driver enclosure. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

3.5 cubes tuned to 35 hz will work very well. That's what I would recommend to you as well.

will this box size work for a 15 inch type R? should it be smaller/tuned lower??

perfect
