2025 f150 supercrew build?

You guys are twisting my arm into 2 12's.....
As stated, the MTI box over on the other forum has a great reputation / following, etc...
but so does the Fox box...
wonder how 2 sealed 12's would compare to 2 ported 10's....

I can do the MTI box but more money, then more money for the 12" JL's or whatever sub over the 10"....
Also the design of the fox box, will take full size non shallow subs as it has a 6.25" mounting depth with a 7" magnet.

In general characteristically sound quality & performance is better at lower volume using a sealed over ported, or amI mistaken?
Meaning a sealed box will hit harder at lower volume over a ported box?

The main difference is ported enclosure will be louder, but the ported enclosure will be peaky around 40hz. OTOH, the sealed 12s will have smoother response curve.

As a general rule of thumb ported hits harder and will sound better with rap, hip-hop, EDM, etc, but will make the bass sound overbearing and muddy with rock, metal, country, jazz, classical, blues, etc. You have to decide which works better for you tastes.

Nobody is twisting anyone's arm, go ahead and grab a dual 12 downfire sealed enclosure. Cone is kang after all they say... but others know better. The Diyma/Sq crowd and sealed enclosure nuthuggers always speak up. The last time I designed around a sealed chamber was in a 4th.

Well, there's no denying that bigger is better... right?

And there really isn't a "knows better"; there are just differing opinions, sound characteristics and preferences people have as well as applied science to get the best results, in either box design. Ported enclosures done correctly will be bigger, which is a limiting factor in some, well, many instances, such as the restricted area under a seat.

Yep
Down firing sealed
As big as possible with the lowest fs driver you can find to help dig deep

He's gotta fit this under his rear seat though and he's looking at prefabs vs spending the money for a professionally built ported enclosure tuned nice and low.

Not totally accurate.
At this point, the MTI boxes are dialed in to the subs you decide on. They not prefabbed per say.
But even you said, you prefer sound of a sealed box, you still stand behind that statement?
The MTI box is offered ported.

I had a ported box in my 00 expedition, firing back, 2 fosgate Punch p3? 12's, dont recall what series they were costly..
I do know it pounded & sounded great, I was in my mid 20's, wanted to be loud as possible.
I dont recall the SQ charecteristics of it, probably never bothered listening to it at a moderate level to take in the clarity.....

Multiple people in the box making space over spoken too at this point that offer both forward fire & down / up fire said, if it was their truck they would go down...

At this point a custom isnt much more than a prefab, depending on what youre comparing. As long as I stay away from bottom of the barrel low budget prefabs. Which im sure will sound fine in a sealed environment as long as its the correct air volume,

Ported will definitely pound harder. I'd say you'll get a good 5-6db more if you go ported with an SQL tuning (~35-37hz). If you want to go ported in a more SQ oriented system, then I'd shoot for a set-up tuned more in the 32hz range, but then the port starts eating up a lot of space and you want a sub that is more suited to low tuning (lower FS).

Right, Im sure they sound good...
Just seems like all the teenagers run kicker, atleast in my mind.
But I know they slam, in a downfire, nobody will ever see them.....
Shit im contemplating cheaping out on skarr or ct subs....

Around here, I see a lot more teens with Skar gear than Kicker. I see kicker to be a lot for popular with the older "Rocker" group. It's what was the most popular in the 90's and early 2000's.

I think it was due to budget, its all we can afford back then....
There was no skar back then...
90's & budget minded, if you had a majestic 500 you were in the game....
If you bought a hi-fonics Zues of a giant Orion from Kim at the swap meet, you were rich...

Kicker was the more popular because they had all the different box designs. They had the sub box with horn tweeters, bass reflex, ported, etc... And they came in boxes that will fit behind your truck's seat. They were not in the same price range as the China stuff. They were much more expensive. I remember, because I was working in car audio back then. Yes, the rich kids had Orion, Fosgate, JL Audio, Oz audio, PPI, just to name a few. Kicker was considered an upper brand, but not that "upper." Remember the Blue Thunders? People would put those on the same level as JL Audio. Great, now you just brought back a lot of old memories that now have me reminiscing over.

To be totally honest, Skar would be the considered as the old Jensens. Inexpensive, but gets the job done. Remember, Skar is a China brand where all the components are mass produced and assembled according to what the retailer wants. Skar equipment share the same designs as many other China brands. Some of those brands are:

• CT sounds
• Rockville
• American Bass
• DS18
• NVX

This is why those brands are so much less expensive than the well known brands. If you Google "What car audio shares the same designs as Skar Audio," you will see a list. However, Skar's upper models will be more original in design.

I had 4 10" MTX Blue thunders in both my 1972 Datsun 240 z & my 1991 ford mustang....
I miss those days & both of those cars!!!!!!

I agree, reminiscing........
The good ole days...

 

[slater]

Well, hopefully this time around the CDT's doing me better this go around than last, this time with a DSP from the get go....
Went with CDT all the way around for 3 way sound stage, cashed in on the BF sale theyre offering.
Ive been badgering Dox for weeks, Stevens Tweeter vs cdt es1200...
Sounds like the Stevens would sound better but I went with easy, I like bright.....
Can always swap them out if theyre over the top, not a huge investment there.
went with
hd-690cf 2ohm 6x9 mid woofer front doors
es1200is tweeter
es-03 3" mid range
es-6ex1 6.5" 2ohm coaxial rear doors

Still have paralysis on which downfire sub box & subs....

 

[Jimi77 Premium Member]

I'd probably go Fox for the enclosure. For subs, there are so many good subs out there now-a-days, it's hard to go wrong. If I knew you were looking at Stevens Audio, I would have tried to talk you into his HLCDs.

 

[slater]

The fox box only takes tens according to the owner and not big enough for 12s according to him.
Doc seems to think these Prodigy shallow subs are pretty good, and multiple other folks have also suggested them and they’re cheap.

 

[Jimi77 Premium Member]

I've never heard the Prodigy subs, but the specs look good, plus they'll work in ~.75cuft sealed. And because it works in smaller space, you can tune lower in ported enclosures.
