Ported or Sealed box
 

i am making a poll about sub boxes Ported, sealed or bandpass sub boxes.

i like sealed boxes better than ported.. and ive never heard a bandpass box. it can also depend on the car and where the box is actually located. for example i dont have my alero anymore and theres not seats or trunk blocking me from the box my subs are in where as in the alero the box is in the sealed off trunk

I have a sealed box with 2 12's right now but I had a ported 15 for a while. It's all about preference to be honest. Sealed boxes sound the best inside the car but if you want major bass go ported. With ported boxes though its all about the range its ported for though. At some ranges it will sound great at have mch more bass but if you have to low of a range it will fall on its face. I don't know much about bandpass but I have heard that it really hits hard and doesn't distort the sound as much as just porting.

it really depends on what the ported box is tuned at. a box tuned to 26hz would hit a lot deeper and be louder lower but not so hot on most music. a box tuned to 40 hz would sound better on most music but not so hot on the low end

33hz should be a good medium for bass and sound quality

All types are good for their applications:

Sealed - "tight precise", simple to build, may implement less space

Ported - May select desired tuning in regards to music prference, more efficient when built properly, can get louder off of less power, less forgiving when building, require more space than your typical sealed box

Bandpass - Depending on type: (4th order, 6th order, etc.) Can get loud off of less power, control over frequency response, require more space than your typical ported box

Lots of variables, it really depends on how much space you have to work with and what you plan to get out of your build.

i want to try an experimental build someday with a box tuned to 65hz purely for metal. of course it would need a special kind of sub to be able to handle that. i saw something like it on youtube but i cant find it. looks like it would be intense

People told me you always get more bass out of ported but I had two twelves and use em in a ported for a week then a sealed and the sealed sounded a lot better and seemed louder.

Chances are that your ported box was either built poorly, tuned way too high, or wasn't made to meet your musical taste.

If it were a prefab you were probably tuned at like 44Hz. I have heard a few of these magical ported prefabs and they seem to work like ****. I could build you a box for whatever setup you are running, built to woofer specs, and I guarantee you'd ditch that sealed box. ;)

or it could have been the sub was made for a sealed box. ive put a sub made for a ported in a sealed and laughed as my mids drowned it out by 20% volume and put it in a ported box and it was like 30x louder

True. What subs sleepy?

Metal, you say? A musician buddy of mine had these for sale:

Free air resonance 51 hz

I was going to try them in home as subs, but they don't reach down low enough.

:eek: 4 of those 18"s in a suv playing some winds of plaugue your brain would explode

He's got 4 of them, last I heard, mounted in large stage boxes..

edit: no, looks like he got a bid on 2 of them...

:No:

Please stop.

When I hear winds of plague all I can think of is this

it makes me laugh haha

Well, the poll didn't make that much sense, anyway. A true subsonic system will go well below 32 hz, and to do that with reasonable efficiency, a ported box is called for. I prefer passive radiator or resistive reflex (aka aperiodic).
Sealed box for 60-80 hz or above.

This.

its all about preferrence on a box designed properly.

I like ported myself ive owned and been in many different and for whatever reason I love having a ported box specially when my box with my cheap backup amp 350watt kenwood sounds just as good if not sometimes better then my buddy's sealed sub and his 2000 watt kenwood exelon amp

6Th order bandpass.

Because if you dont have a clue you will self destruct subs and seeing carnage is cool.

Different subs, different boxes. Different tastes, different boxes. Different tastes, different tuning. And it goes on.

There is no sure fire.
