Can you run a sealed and ported sub setup? and/or can you run two different sub sizes in the same setup?

[Upstate607]

So I have two different questions here. First off, can you have a sealed and ported sub setup? Now I see people have asked this before but Im wondering if say you make two enclosures, one sealed, and one ported and then mount them side by side, if that would work out well or not?

Second, if that isnt a good idea, then would you be able to run two different sub sizes (say a 8" and a 12") and then have a eq so that the lows go to the 12" and the highs go to the 8"? And again could these be mounted in the same box and if not, could they be run side to side in seperate enclosures?

No to all those.

No to all those.

I'm only asking because I'm trying to find the best of both worlds. I'd like to have very punchy, fast, responsive bass, but yet I'd like to be able to hit the low notes.

A properly designed and built ported box can do those things no problem. My 8 12" ported wall will play metal with double bass pedal no problem and play to 24hz as well.

What you are describing here is known as a bandpass enclosure. The sub is mounted in a sealed box with the opposite end firing into a ported box

Alot of users love the loud boominess while others opine that it is mostly a one note wonder. Meaning that it plays a small band of the spectrum very loud while lacking on the rest. I would personally advise using a sealed enclosure. You would be surprised how low it can go, and uses less space.

Please don't. The last time someone did a pos retard was elected to president.

Get rid of The Affordable Care Act. I'll give you that one. The rest, you can eat a dick.

Not just the ACA, they plan on going back to the Paris climate accord. So fuel will go up just like in the Obama era, $5 a gallon. Probably will strike a nuclear deal with Iran and close the embassy in Jerusalem just as a big ole fugk you to Isreal. Fugging up all the progress done by Trump, just out of spite.
Oh well. We'll see if the **** hits the fan and sprays us all.

First off f*ck Isreal. Wtf is wrong with u people? Everyone should be wanting nuke deals, if not then you are a f*cking moron. I can't even with that five dollar gas ****, no way you are THAT dumb.

I don't understand the first half of this sentence. The second yes. When you promise in an accord to lower your global emmissions, you must use less pollutants. The most common pollutant is transportation. So you stop renewing drilling permits, which in turn lowers the supply of crude oil and raises the demand. Low supply and high demand causes high prices. High prices lead to less cruising by most people, which in turn means less pollution.
The trucking industry will also have to pass on the diesel prices to consumers to be able to stay afloat. So product prices may rise as a result of this climate accord.

A subwoofer is only required to cover 2-3 octaves, there is absolutely no reason that needs to be split into two different speakers or speaker sizes. Also, 'punchy bass' is midbass, not subbass, and is localizable by your ears so it should be in the front stage, not your trunk.

Sorry that some people here have Trump living in their head rent free and can't seem to get thru a car audio thread without bringing him up.

Exactly what Audioholic said, if you want to expand your midbass but your doors speakers sound like ass then sound deaden your doors and upgrade the front to expand downward, don't expand the back upwards unless you want to lose the low end which they're better at. You can get into complicated enclosure designs that allow a fairly flat EQ curve that expands that 3 octave limit, but you're better off letting your subs do what they do well and midranges do what they do well.

Also there's a big misnomer in the car audio community that subwoofer size is where you get your low range from. There are 8" subs that outperform 15" subs on the low end in their ideal enclosures, it's just not that simple.

You can have a 8" tuned higher enclosure and 15" tuned lower enclosure near each other but you're going to get frustrating overlap at the crossover or deal with a gap, it's better by all accounts to invest that money into deadening. Even OEM speakers will sound good (usually) in a well deadened door compared to great speakers in a hollow tin can of a door. Also if you have a good high power 15" speaker that's tuned low then most likely you're not going to have room in your trunk opening for other enclosures.

I'm late to this one but I feel I had to give my input/experience.
I thought just like you at one point. I even bought 4 15s and 4 8s with plans to do what you're describing. I posted on a car audio page and got absolutely torn to shreds for even asking. 4 years later I have learned a lot and I have an answer along with reasoning.
In general you don't want to mix different sub sizes. Doing so produces distortion because 2 sunb will produce the sound wave at different power levels. Not watts, simply the fact that the speakers are playing the same note and the drivers aren't equally matched.
I wanted system with all the punch of small sub in a sealed box accompanied by the deep low bass bigger subs are known for.
There are a few different routes you can go to achieve the sound you're looking for but in my experience a 4th order bandpass can be designed to meet your needs. With enough cabin gain you can play down onto the 20s while simultaneously having a tight punchy response.

I can put a sealed box inside of a ported box for you. I can even put a ported box inside of a ported box for you.
