Sealed or Ported Sub Box

What type of sub box will be better when the top is off? I'm wanting to put two 12" subs in the box. What brand do you recommend? Please post pics!!

I thought about that but decided it would be too expensive for what I want to pay (I'm not building the box) and I want to see the subs

My bandpass enclosure cost about 15$ and 4-5 hours of work.

My 10" sub is now way deeper and louder than my GFs 2x 12" sub.
And I still have some room for other things in my trunk.
She has only the sub in her JK trunk and its full.

Never mind on the price. I have a JKU so plenty of room. Do you have a pic of your box

I personally prefer the sound of a sealed enclosure, but in my JK I have a ported box with a single 12. Best bang for the buck ported is the way to go. Beware, just buying a premade ported box may not make you happy. I'd have the box built, air space and tuning the port come into play when determining if you sub/box will sound any good.

i think it depends on what you listen to. if you listen to rock go with a sealed enclosure, if you listen to rap go with a ported enclosure. as for what size you would need depends on the specs listed by the sub manufacturer.

Most sub enclosures you can buy are build for closed normal cars.
They will sound different in an open and loud Jeep.

That's why i built my own bandpass enclosure. I tested and had many different closed and ported enclosures in my jeep before. But I wasnt happy with them.

Does your bandpass help protect from weather? And would you build one box or two boxes for 2 12"?

as long as the ports are not facing up than the weather shouldn't be an issue damaging the sub(s), but the enclosure may need more than just carpeting if its gonna get wet. and you can build a bandpass that fits 2 subs.

Ported was not loud and deep enough for me. The engine, tire and wind was too loud for that.

In a bandpass enclosure the sub chassis is inside the box. There is only the port that's open.

And a bandpass is way louder.

Green is my sub in a ported and purple in a BP box.

You can paint the box with bedliner.
Then its water protected.

Because of the louder and better sound i installed the port on top of the box.

It has more to do with building the box to the specs of the sub than the box itself.

I really dislike the sound of a bandpass box. Entirely too peaked across the tuning band with horrible rolloff curves. Maybe I just haven't heard a BP box that's been designed correctly as most I've seen are more about having plexiglass/chrome/neon and being wired at 15Ohm!!

I personally prefer a ported enclosure. I like the amount of low end extension you can add by tuning to 28 or 30 Hz. They're easy to design, easy to build, add a little more spl (again, design specific) and have much better low frequency extension. They're not as flat as a sealed enclosure can be but I really doubt that'll be very important to anyone in a Jeep as the listening environment is far less than ideal.

I vote ported in every application for my personal preference.

I don't know how the space is in the JK's, but I know one 12" ported is gonna be a bit of a squeeze in my TJ.

If you can get enough volume for ported dual 12's, DO IT!!!!

I gave up competing about 8 years ago. Its a single pioneer flat sub with half of a MTX T1004 bridged on it. Box is 55 wide 16 tall, 2.5 inches at the top, and 4 inches at the bottom. One 3" x 16" port.

I have researched the question in the past. -Simple answer is that a Sealed enclosure will have a good flat frequency response, but is less efficient. A Ported enclosure is more efficient but has a resonant frequency based on the size of the enclosure and the size of the port, and tends to peak at this frequency.
Ported Enclosures generally are louder, but tend to be more "boomy". Sealed enclosures need more watts to drive them for the same Sound Pressure Level.
I prefer the sound of Sealed Enclosures myself, but a well designed ported enclosure can sound good also. I have had both.
If it makes any difference, I worked at McIntosh Labs while I was going to tech school in the 70's.

Bandpass enclosures have a hump at the tuning frequency and are basically a 1 octave box. To fill in the rest of the specturm you really need to add a good midbass section (like 8") crossed over around 50 -80 hz with the cut off around 120-150 hz nd then a strong
Ported enclosures are more efficient at the tuning frequency and can be eq'd well on the top side. Agood ported enclosure takes more design for building for the speaker parameters and to work correctly. They are also harder to build correctly.
Sealed enclosurers are wattage hogs but because of the vacume in the box from being sealed gives more control to the speaker. This is good for bass heavy music like rap.
The ported or sealed both work well with fullrange speakers to back them up. This is helpful because you really need less speakers and amps to fill the spectrum well.
I have always enjoyed ported myself but also use up to 4 different electronic crossover sections which also means more amps. This gives me a more efficient systrm without having to make a speaker to work in a audio section that may cause damage.
